>> JASON HIRSCHHORN: Karibu
CS50 sehemu, kila mtu.

3
00:00:08,650 --> 00:00:11,430
Jina langu ni Jason Hirschhorn.

00:00:11,430 --> 00:00:15,850
Nina mengi ya TFS yako, lakini mengi ya
watu hopefully kuwa kujiunga na sisi

5
00:00:15,850 --> 00:00:20,420
online, ugani wanafunzi au wanafunzi
kujaribu kuangalia kupitia sehemu kama

6
00:00:20,420 --> 00:00:22,830
amekosa sehemu zao kwamba wiki au
tu catch up kama walitaka

7
00:00:22,830 --> 00:00:24,510
kupitia upya baadhi ya vifaa.

8
00:00:24,510 --> 00:00:30,060
>> Hivyo kama kwa muhtasari, ambayo yote
wa una kusoma, sahihi?

9
00:00:30,060 --> 00:00:31,390
Mimi naona mengi ya nods kichwa.

10
00:00:31,390 --> 00:00:34,220
Sehemu kutoa kwa fursa
kuchunguza ya shaka

11
00:00:34,220 --> 00:00:37,420
nyenzo katika mazingira ionekane zaidi,
kama vile kupiga mbizi katika

12
00:00:37,420 --> 00:00:38,810
shughuli za mikono.

13
00:00:38,810 --> 00:00:41,230
>> Hivyo kwamba kimsingi nini sisi ni
kwenda kufanya kila wiki.

14
00:00:41,230 --> 00:00:45,090
Tunakwenda kupitia nini tuna
kuamua kuwa muhimu zaidi

15
00:00:45,090 --> 00:00:49,170
mada kufunikwa katika hotuba, na ndio
pengine pia muhimu sana na

16
00:00:49,170 --> 00:00:52,780
zaidi uwezekano wa kuja kwenye seti tatizo
na katika mafumbo, na katika coding yako

17
00:00:52,780 --> 00:00:53,970
maisha ya nje ya CS50.

18
00:00:53,970 --> 00:00:57,260
Hivyo sisi ni kwenda na kwenda katika mada hizo,
kujadili yao, kwenda juu yao,

19
00:00:57,260 --> 00:01:00,660
kujibu maswali yoyote unaweza guys kuwa, na
kisha tunakwenda kufanya mengi ya

20
00:01:00,660 --> 00:01:02,250
mazoezi ya matatizo katika coding.

21
00:01:02,250 --> 00:01:04,239
>> Wewe wote kuletwa Laptops,
ambayo ni ya ajabu.

22
00:01:04,239 --> 00:01:05,710
Hii ni sayansi ya kompyuta ya darasa.

23
00:01:05,710 --> 00:01:10,070
Hata hivyo, mengi ya mazoezi ya kufanya,
huwezi haja Laptops yako kwa.

24
00:01:10,070 --> 00:01:11,720
Unaweza kufanya nao juu ya karatasi.

25
00:01:11,720 --> 00:01:13,580
Kwamba ni jinsi gani wewe ni kwenda
kufanya nao juu ya Quizzes.

26
00:01:13,580 --> 00:01:16,450
Na kwa kweli, hilo ni njia kubwa ya
kweli kujua kwamba wewe jinsi ya kufanya

27
00:01:16,450 --> 00:01:19,720
kitu kama huna Angalia 50 hadi
kumtegemea au kufanya kutegemea, kuwaambia

28
00:01:19,720 --> 00:01:20,620
umefanya makosa yoyote.

29
00:01:20,620 --> 00:01:25,670
>> Hivyo wewe ni kuwakaribisha kwa kanuni ya
appliance au run.cs50.net, ambayo ni

30
00:01:25,670 --> 00:01:29,770
chombo mwingine kwamba utapata na kanuni
online, lakini mimi pia ingekuwa kupendekeza, kama

31
00:01:29,770 --> 00:01:32,280
wewe si walijaribu hivyo, kwa kutumia karatasi
ya karatasi na kujaribu haya mazoezi

32
00:01:32,280 --> 00:01:33,640
matatizo katika karatasi.

33
00:01:33,640 --> 00:01:35,330
Sababu tena, kwamba hatimaye
nini wewe kwenda kuwa

34
00:01:35,330 --> 00:01:37,430
kuombwa kufanya juu ya mafumbo.

35
00:01:37,430 --> 00:01:44,080
>> Basi hebu kuanza na yetu
ajenda kwa leo.

36
00:01:44,080 --> 00:01:47,710
Tunakwenda kwenda juu ya baadhi ya kanuni kwa
sehemu yetu, basi sisi ni kwenda kupiga mbizi

37
00:01:47,710 --> 00:01:51,180
katika arrays, kazi, na mstari amri
hoja, ambayo ni nini nyie

38
00:01:51,180 --> 00:01:56,200
na mifuniko ya wiki hii iliyopita katika hotuba
na kisha Jumatatu, na kile utakuwa kufunika

39
00:01:56,200 --> 00:01:57,330
zaidi ya kesho.

40
00:01:57,330 --> 00:01:59,060
Na kisha hatimaye, tunakwenda
kuzungumza kuhusu pset2.

41
00:01:59,060 --> 00:02:03,640
Kama mimi naweza kupata show ya mikono kama wewe
si inaonekana saa mbili kuweka tatizo

42
00:02:03,640 --> 00:02:04,890
vipimo.

43
00:02:04,890 --> 00:02:07,060

44
00:02:07,060 --> 00:02:08,120
Tutaweza kusema kila mtu.

45
00:02:08,120 --> 00:02:09,419
Ajabu.

46
00:02:09,419 --> 00:02:12,070
>> Tutaweza kuzungumzia seti tatizo katika kidogo,
lakini kama kusoma kuweka tatizo

47
00:02:12,070 --> 00:02:14,340
vipimo, hiyo ni
wote unahitaji kufanya.

48
00:02:14,340 --> 00:02:18,370
Kama unaweza kusoma kwamba kabla ya kuja
darasani na sehemu ya juu ya Jumanne, utakuwa

49
00:02:18,370 --> 00:02:19,220
kuwa na nafasi kubwa.

50
00:02:19,220 --> 00:02:21,680
Tunaweza kwenda kwa kuweka tatizo,
ambayo ni nini tunakwenda

51
00:02:21,680 --> 00:02:22,090
kufanya mwishoni.

52
00:02:22,090 --> 00:02:23,500
Tunakwenda kupitia
mantiki, kuhakikisha

53
00:02:23,500 --> 00:02:24,710
kila mtu juu ya ukurasa huo.

54
00:02:24,710 --> 00:02:28,650
>> Mimi nataka ninyi kuwa na uwezo wa kuondoka Jumanne
hisia vizuri sana na kile

55
00:02:28,650 --> 00:02:31,560
haja ya kufanya kwa ajili ya tatizo kuweka wiki hii,
na kama huna, mimi kwa furaha

56
00:02:31,560 --> 00:02:33,050
kukaa baada na kazi na wewe.

57
00:02:33,050 --> 00:02:36,850
Lakini hiyo ni jambo moja kwamba una
kufanya lakini nadhani itakuwa kweli smart,

58
00:02:36,850 --> 00:02:40,500
tu kusoma kuweka tatizo
vipimo na darasa juu ya Jumanne,

59
00:02:40,500 --> 00:02:42,640
ambayo inaonekana kama
mengi ya nyie alivyofanya.

60
00:02:42,640 --> 00:02:45,810
>> Mimi itabidi kuanza na ajenda ya kila aina ya darasa
ili kujua wapi tunakwenda.

61
00:02:45,810 --> 00:02:49,520
Hii pia ni msaada kwa ajili ya watu kuangalia
online kwa sababu kila sehemu

62
00:02:49,520 --> 00:02:53,540
ni rangi coded, hivyo kama unataka kuja
nyuma na kuangalia tu dakika 10 badala

63
00:02:53,540 --> 00:02:56,950
kuliko sehemu nzima dakika ya 90, wewe
unaweza tu kwenda sehemu ya rangi coded

64
00:02:56,950 --> 00:02:57,890
na kuangalia sehemu hiyo.

65
00:02:57,890 --> 00:03:01,510
Hivyo nimekuwa alijaribu kuvunja yao juu katika nzuri
modules kwamba itaruhusu -

66
00:03:01,510 --> 00:03:03,960
kama unataka kuja nyuma na tathmini,
au wanafunzi wengine ambao ni tu

67
00:03:03,960 --> 00:03:05,350
kuangalia sehemu ya kupitia upya -

68
00:03:05,350 --> 00:03:08,130
kupata kitu maalum wao
wanataka kwa makini na

69
00:03:08,130 --> 00:03:10,480
na kujifunza zaidi juu.

70
00:03:10,480 --> 00:03:11,390
Tamu.

71
00:03:11,390 --> 00:03:12,180
>> Kanuni.

72
00:03:12,180 --> 00:03:13,680
Mimi nina kiongozi maridadi juu ya chuo.

73
00:03:13,680 --> 00:03:14,900
Sijui kama mtu yeyote alifanya maridadi.

74
00:03:14,900 --> 00:03:16,280
Je, mtu yeyote kufanya maridadi?

75
00:03:16,280 --> 00:03:17,100
Mtu mmoja alifanya maridadi.

76
00:03:17,100 --> 00:03:18,430
Watu wawili walifanya maridadi.

77
00:03:18,430 --> 00:03:19,250
Kutisha.

78
00:03:19,250 --> 00:03:22,360
Hivyo maridadi ni mwaka wa Kwanza Nje
Mwelekeo Programu.

79
00:03:22,360 --> 00:03:27,240
Sisi kuchukua freshmen katika Woods na kufanya
uzoefu zaidi ya kichawi ya

80
00:03:27,240 --> 00:03:28,830
maisha yao, sahihi?

81
00:03:28,830 --> 00:03:29,220
Yeah.

82
00:03:29,220 --> 00:03:30,080
Sauti kuhusu haki.

83
00:03:30,080 --> 00:03:36,360
>> Hivyo mimi tu alitaka kuanza yetu ya kwanza
kifungu kwa kujadili baadhi ya kanuni

84
00:03:36,360 --> 00:03:38,860
kwa ajili ya darasa na uhusiano wetu
sababu nadhani

85
00:03:38,860 --> 00:03:40,010

00:06:53,230 --> 00:06:58,010
Mimi naenda kuwa grading kila mtu ambaye ni
katika sehemu yangu, au bao yako

156
00:06:58,010 --> 00:06:59,020
tatizo seti.

157
00:06:59,020 --> 00:07:01,240
Wewe si wamerejea tatizo
kuweka zero au moja bado.

158
00:07:01,240 --> 00:07:02,250
Tunasikitika juu ya hilo.

159
00:07:02,250 --> 00:07:04,970
Ilichukua sisi muda na hatimaye
kukaa sehemu, na sasa

160
00:07:04,970 --> 00:07:05,560
tunaweza kuanza grading.

161
00:07:05,560 --> 00:07:09,560
>> Mimi itabidi kupata yao nyuma yenu
haraka iwezekanavyo.

162
00:07:09,560 --> 00:07:11,890
Hizo ni baadhi ya yangu
advisees huko nje.

163
00:07:11,890 --> 00:07:14,150
Mimi itabidi kupata yao nyuma yenu
haraka iwezekanavyo.

164
00:07:14,150 --> 00:07:18,046
Na kwa ajili ya tatizo kuweka mbili, tutaweza kuwa juu ya
ratiba na tutaweza kuanza kupata yao

165
00:07:18,046 --> 00:07:20,440
na wewe pretty haraka baada ya
wewe kugeuka wasitoke

166
00:07:20,440 --> 00:07:24,130
>> Baada ya kupata tatizo lako kuweka nyuma, wewe
kupata alama, kama unajua kutoka

167
00:07:24,130 --> 00:07:28,150
kusoma silabasi - usahihi,
kubuni, upeo, na style alama.

168
00:07:28,150 --> 00:07:29,760
Utapata pia kupata maoni.

169
00:07:29,760 --> 00:07:32,160
maoni ni muhimu zaidi
kuliko alama.

170
00:07:32,160 --> 00:07:33,780
Nadhani ni salama kusema kwamba.

171
00:07:33,780 --> 00:07:37,930
>> Alama ni idadi tu
moja hadi tano.

172
00:07:37,930 --> 00:07:38,930
Ni vigumu kusoma katika wale.

173
00:07:38,930 --> 00:07:40,720
Ni vigumu kuboresha kutoka kwa wale.

174
00:07:40,720 --> 00:07:44,460
Lakini maoni mapenzi kumweka nje maalum
mambo walifanya vizuri au maeneo

175
00:07:44,460 --> 00:07:48,360
unaweza kuboresha na kutoa baadhi ya
mawazo kwa ajili ya baadaye au mbadala

176
00:07:48,360 --> 00:07:49,160
njia za kufanya mambo.

177
00:07:49,160 --> 00:07:52,270
>> Hivyo tafadhali, tafadhali, tafadhali soma
kupitia maoni.

178
00:07:52,270 --> 00:07:54,190
Mimi kuweka muda mwingi katika
wale maoni.

179
00:07:54,190 --> 00:07:57,190
Tafadhali soma kwa njia yao na si tu
kitabu chini kwa chini ya

180
00:07:57,190 --> 00:08:01,890
PDF, kuangalia kwa alama yako, au kwenda online
na kupata alama yako, na kisha kupuuza

181
00:08:01,890 --> 00:08:02,800
maoni.

182
00:08:02,800 --> 00:08:03,910
Si kwamba jinsi wewe ni
kwenda kupata bora.

183
00:08:03,910 --> 00:08:06,550
Hiyo si jinsi wewe ni kwenda kuongeza
yako alama hatimaye, tu

184
00:08:06,550 --> 00:08:07,340
kwa kuangalia alama.

185
00:08:07,340 --> 00:08:08,760
Tafadhali kuangalia maoni hayo.

186
00:08:08,760 --> 00:08:13,240
>> Na pamoja mstari wa matarajio ya juu,
tena, kama nilivyosema, wewe

187
00:08:13,240 --> 00:08:14,260
yanaweza alifunga kutoka moja kwa njia ya tano.

188
00:08:14,260 --> 00:08:17,120
Wawili wawili, watatu, na fours ni
kubwa wengi wa alama

189
00:08:17,120 --> 00:08:17,940
wewe ni kwenda kuwa kupata.

190
00:08:17,940 --> 00:08:20,180
Ndio na umri wa miaka mitano ni wawili kweli nadra.

191
00:08:20,180 --> 00:08:21,720
Daima kuna mambo
tunaweza kufanya vizuri zaidi.

192
00:08:21,720 --> 00:08:23,490
Kila mimi Kanuni mpango, kuna
daima kitu mimi

193
00:08:23,490 --> 00:08:24,800
wangefanya vizuri zaidi.

194
00:08:24,800 --> 00:08:28,740
>> Hivyo badala ya kusema wewe kupata tano
kila wakati juu ya kila kitu na alifanya

195
00:08:28,740 --> 00:08:31,960
kila kitu kamili, sidhani yoyote
wa kwetu kweli wanaamini kwamba sisi - au

196
00:08:31,960 --> 00:08:34,830
hopefully, hatuwezi kufanya kila kitu
kamili kila wakati.

197
00:08:34,830 --> 00:08:37,010
Hivyo si kuwa na wasiwasi kama wewe
hakuwa na kupata tano.

198
00:08:37,010 --> 00:08:40,470
tano haina ramani kwenye, nne
haina ramani kwenye B, tatu gani

199
00:08:40,470 --> 00:08:42,950
si ramani kwenye C. Hiyo si
jinsi alama kazi.

200
00:08:42,950 --> 00:08:48,140
>> Kama Daudi amesema mara nyingi, katika
mwisho wa muhula wote wa ya alama yako na

201
00:08:48,140 --> 00:08:53,390
pembejeo kutoka kwangu, TF yako, kuja pamoja
na kuamua daraja ya mwisho kwa ajili yenu.

202
00:08:53,390 --> 00:08:56,760
Lakini tena, siyo mitano,
, Nne, B, nakadhalika.

203
00:08:56,760 --> 00:09:01,150
Hivyo nina kwenda na matarajio ya juu
kwa ajili ya wewe guys.

204
00:09:01,150 --> 00:09:03,670
Mimi nina kwenda kutarajia tatizo nzuri
seti na mimi nina kwenda kutoa

205
00:09:03,670 --> 00:09:05,010
wewe maoni kama vile.

206
00:09:05,010 --> 00:09:07,430
Na si kwenda maana wewe ni
kwenda kupata daraja mbaya zaidi.

207
00:09:07,430 --> 00:09:09,760
Wewe ni hadhi katika suala la
maendeleo yako kutoka wiki

208
00:09:09,760 --> 00:09:11,260
sifuri hadi mwisho kozi ya.

209
00:09:11,260 --> 00:09:17,190
>> Na hatimaye, katika suala la juu
matarajio ya darasani, mimi upendo wakati

210
00:09:17,190 --> 00:09:18,460
watu kushiriki.

211
00:09:18,460 --> 00:09:23,180
Naelewa baadhi ya watu kuhisi zaidi au
chini ya starehe ya kushiriki.

212
00:09:23,180 --> 00:09:26,050
Watu wengine wanashiriki
si kwa kunyoosha mikono yao na

213
00:09:26,050 --> 00:09:27,320
kuzungumza wakati wote.

214
00:09:27,320 --> 00:09:30,570
Lakini sisi katika darasa hili ni kwenda kuwa
kufanya mengi ya matatizo kidogo, mengi

215
00:09:30,570 --> 00:09:33,770
ya maswali ya mini, na kisha baadhi
kubwa coding matatizo.

216
00:09:33,770 --> 00:09:36,760
Hivyo dhahiri kazi mazoezi haya ya nje
wakati sisi kufanya nao kwenye kompyuta yako au juu ya

217
00:09:36,760 --> 00:09:37,900
karatasi.

218
00:09:37,900 --> 00:09:40,933
>> Lakini mimi itabidi pia kukupa muda kabla ya
mtu yeyote milele ina kujibu baadhi

219
00:09:40,933 --> 00:09:42,220
ya maswali mimi kuuliza.

220
00:09:42,220 --> 00:09:44,930
Hivyo kwa sababu nitakupa baadhi ya wakati
kufikiri juu yake, kwa sababu tunakwenda

221
00:09:44,930 --> 00:09:49,380
kufanya mambo katika washirika wakati mwingine,
Mimi kutarajia kila mtu

222
00:09:49,380 --> 00:09:52,150
kuwa wanaohusika kiasi fulani.

223
00:09:52,150 --> 00:09:56,030
Na kwa ajili ya ukosefu wa muda bora, kuna
pengine kuwa baridi wito, ambayo

224
00:09:56,030 --> 00:09:59,045
ni ambapo kila mtu atakuwa na nafasi
kufikiri juu ya jibu, na kisha

225
00:09:59,045 --> 00:10:01,150
Mimi nitakuita juu yenu, na kisha
utasikia wanasema jibu.

226
00:10:01,150 --> 00:10:05,200
>> Msiwe na wasiwasi au kuwa na hofu juu ya hilo.

227
00:10:05,200 --> 00:10:08,610
Nimekuwa kufanyika katika siku za nyuma na tumekuwa kupatikana
kwamba ni zaidi ya mafanikio,

228
00:10:08,610 --> 00:10:11,810
pia kusoma utafiti wa kielimu juu yake ili
au kuamua kama ilivyokuwa

229
00:10:11,810 --> 00:10:12,640
nzuri mbinu.

230
00:10:12,640 --> 00:10:15,790
Ni msaada sana, hasa kama wewe
kuwapa wanafunzi muda wa kufikiri juu

231
00:10:15,790 --> 00:10:20,070
majibu na wala kuwafanya kuja tu
nje na kusema ni haki mbali bat.

232
00:10:20,070 --> 00:10:22,620
Lakini kama huna kujisikia vizuri
kujibu, mimi nina pia nzuri katika

233
00:10:22,620 --> 00:10:25,370
kuhisi kwamba nje, na sisi siyo kwenda
kuweka wewe juu ya doa, hasa juu ya

234
00:10:25,370 --> 00:10:28,240
kamera, hata kama hakuna
wewe ni juu ya kamera hivi sasa.

235
00:10:28,240 --> 00:10:32,250
>> Basi hizo kanuni mimi.

236
00:10:32,250 --> 00:10:34,670
Jambo moja zaidi pamoja na mistari
mkutano wa katikati.

237
00:10:34,670 --> 00:10:36,490
Mimi naenda kukupa guys
kura ya maoni.

238
00:10:36,490 --> 00:10:38,310
Tafadhali nipe maoni pia.

239
00:10:38,310 --> 00:10:46,190
Kuna tovuti, sayat.me/cs50.

240
00:10:46,190 --> 00:10:48,380
Hivyo ni maoni ya kweli.

241
00:10:48,380 --> 00:10:50,730
Kama unataka kumpa wakati sehemu,
Mimi kupata barua pepe wakati yanapotokea.

242
00:10:50,730 --> 00:10:53,820
Tutaweza kuchukua mapumziko katika kidogo, hivyo mimi itabidi
kuangalia njia ya maoni basi.

243
00:10:53,820 --> 00:10:55,970
Kama umewahi kuwa maoni yoyote,
tafadhali unipe huko.

244
00:10:55,970 --> 00:11:01,380
>> Kama wewe nipe maoni juu ya Q, hiyo ni
ajabu, lakini hiyo ni mwongozo

245
00:11:01,380 --> 00:11:02,570
kwamba kufanya mwishoni.

246
00:11:02,570 --> 00:11:05,690
Lakini kwamba itakuwa mwisho wa muhula wa hivyo
Mimi si kuwa na uwezo wa kuchukua yoyote ya kuwa

247
00:11:05,690 --> 00:11:08,620
maoni na kugeuka ndani ya kufundisha
nyie bora.

248
00:11:08,620 --> 00:11:11,020
Hivyo tafadhali, kama una
maoni, unipe.

249
00:11:11,020 --> 00:11:12,010
Nampenda maoni.

250
00:11:12,010 --> 00:11:14,490
Nyuma na maridadi, sisi kupata maoni
wakati wote.

251
00:11:14,490 --> 00:11:18,610
>> Unaweza kunipa pluses, mambo mema,
delta, mambo naweza kuboresha juu.

252
00:11:18,610 --> 00:11:20,600
Unaweza kutoa maoni juu ya mavazi yangu.

253
00:11:20,600 --> 00:11:24,170
Ambayo si kuwa kama msaada, lakini wewe ni
welcome maoni juu ya yoyote na

254
00:11:24,170 --> 00:11:24,570
kila kitu.

255
00:11:24,570 --> 00:11:26,280
Tafadhali, tafadhali nipe maoni.

256
00:11:26,280 --> 00:11:28,740
Mimi thamani yake mengi na ni
ina maana kubwa kwangu.

257
00:11:28,740 --> 00:11:31,760

258
00:11:31,760 --> 00:11:33,280
>> Moja zaidi ya kawaida, furaha.

259
00:11:33,280 --> 00:11:34,530
Tunakwenda kuwa na mengi ya furaha.

260
00:11:34,530 --> 00:11:36,930
Hopefully katika kozi hii, utakuwa
kuwa na mengi ya furaha.

261
00:11:36,930 --> 00:11:38,780
Tutaweza kuwa pipi saa sehemu.

262
00:11:38,780 --> 00:11:40,040
Tutaweza kuwa na muziki.

263
00:11:40,040 --> 00:11:45,510
Tutakuwa hopefully kupata kujua moja
mwingine kiasi fulani vizuri, hivyo nataka

264
00:11:45,510 --> 00:11:47,690
hii kuwa furaha, walioshiriki uzoefu.

265
00:11:47,690 --> 00:11:50,890
>> Najua baadhi ya wamekufa katika
mihadhara wewe alikuwa mapema leo,

266
00:11:50,890 --> 00:11:53,750
hivyo hopefully kwamba si
kuwa kesi sasa.

267
00:11:53,750 --> 00:11:55,960
Na kama ni kesi ya sasa, tu
wala koroma kwa sababu kwamba nguvu

268
00:11:55,960 --> 00:11:57,580
kuwa hawakupata juu ya kamera.

269
00:11:57,580 --> 00:11:58,770
Tamu.

270
00:11:58,770 --> 00:12:04,020
Maswali yoyote, maoni, au wasiwasi
kabla mimi hoja juu kuhusu kitu tumekuwa

271
00:12:04,020 --> 00:12:05,270
alizungumzia kuhusu?

272
00:12:05,270 --> 00:12:08,620

273
00:12:08,620 --> 00:12:11,350
Kubwa.

274
00:12:11,350 --> 00:12:14,830
>> Hivyo sisi ni kwenda
katika arrays kwanza.

275
00:12:14,830 --> 00:12:17,140
Hii ni jinsi ya kufanya safu.

276
00:12:17,140 --> 00:12:18,410
Tumeona hili kabla.

277
00:12:18,410 --> 00:12:21,830
Una aina ya data, una
jina, na kisha una ukubwa.

278
00:12:21,830 --> 00:12:24,430
Hapa hapa, mimi kujenga arrays mbili.

279
00:12:24,430 --> 00:12:30,360
Wa kwanza ni safu ya wahusika,
na ina nafasi ya 26.

280
00:12:30,360 --> 00:12:33,790
moja ya pili ni safu ya
alama, na ina tatu

281
00:12:33,790 --> 00:12:35,390
mazingira kwa ajili ya integers tatu.

282
00:12:35,390 --> 00:12:35,827
Ndiyo?

283
00:12:35,827 --> 00:12:38,200
>> MWANAFUNZI: Je, wote ni wa slides hizi
inapatikana mahali fulani kwa ajili yetu?

284
00:12:38,200 --> 00:12:38,850
>> JASON HIRSCHHORN: Mkuu swali.

285
00:12:38,850 --> 00:12:40,650
swali lilikuwa, wote ni wa
haya slides inapatikana?

286
00:12:40,650 --> 00:12:40,920
Ndiyo.

287
00:12:40,920 --> 00:12:43,420
Wote wa slides haya itakuwa inapatikana,
na katika siku zijazo, mimi itabidi email yao kwa

288
00:12:43,420 --> 00:12:44,640
wewe kabla ya sehemu.

289
00:12:44,640 --> 00:12:47,340
Lakini leo, kwa sababu hii ni mara ya kwanza
wiki, tulikuwa na kuanza marehemu.

290
00:12:47,340 --> 00:12:49,675
Hivyo kwa kawaida, utapata slides hizi, lakini
watakuwa inapatikana online na

291
00:12:49,675 --> 00:12:52,420
Mimi itabidi email yao na wewe
haki baada ya darasa.

292
00:12:52,420 --> 00:12:54,140
Maswali yoyote nyingine?

293
00:12:54,140 --> 00:13:01,330
>> Hivyo tena, arrays ni masanduku, kwa kukosa
neno bora zaidi, yaani kushikilia nyingi

294
00:13:01,330 --> 00:13:06,420
mambo ya aina moja ya data, na wao ni
karibu na mtu mwingine katika kumbukumbu.

295
00:13:06,420 --> 00:13:11,370
Na hivyo tena, hii ni jinsi gani unaweza
kufanya aina mbili ya arrays.

296
00:13:11,370 --> 00:13:15,090
>> Hivyo baada ya kiunda safu yako na
kwamba line ya kwanza - int alama, bracket

297
00:13:15,090 --> 00:13:17,430
tatu, karibu bracket - wewe
wanataka initialize.

298
00:13:17,430 --> 00:13:19,050
Unataka kuweka baadhi ya maadili katika huko.

299
00:13:19,050 --> 00:13:24,660
Na hii ni jinsi ya kuweka maadili katika baadhi ya
huko, tu kuchagua indice na

300
00:13:24,660 --> 00:13:25,670
kuandika idadi.

301
00:13:25,670 --> 00:13:27,130
Hebu kuteka hii juu ya bodi.

302
00:13:27,130 --> 00:13:28,270
Kila mtu anaweza kuona?

303
00:13:28,270 --> 00:13:29,030
Kila mtu anaweza kuona.

304
00:13:29,030 --> 00:13:30,790
Tamu.

305
00:13:30,790 --> 00:13:36,550
>> Ili kwenda kuwa yangu
safu inayoitwa alama.

306
00:13:36,550 --> 00:13:37,730
Kama unaweza kuona, ni kawaida tatu.

307
00:13:37,730 --> 00:13:39,210
Kuna masanduku ya tatu huko.

308
00:13:39,210 --> 00:13:43,120
Kila mmoja unaweza fit nini
aina ya aina data?

309
00:13:43,120 --> 00:13:43,790
>> MWANAFUNZI: Integer.

310
00:13:43,790 --> 00:13:45,250
>> JASON HIRSCHHORN: integer
katika hii moja.

311
00:13:45,250 --> 00:13:48,790
Tuliandika alama int, na neno la kwanza
ni aina ya data kwamba kinaendelea

312
00:13:48,790 --> 00:13:50,910
kwenda katika masanduku katika safu hiyo.

313
00:13:50,910 --> 00:13:52,160
Hivyo siwezi fit tatu.

314
00:13:52,160 --> 00:13:54,880

315
00:13:54,880 --> 00:13:57,000
Kwa nini nina sifuri hadi
huko kwenye bodi?

316
00:13:57,000 --> 00:13:59,240
Kwa nini ni kusema alama sifuri sawa na 1?

317
00:13:59,240 --> 00:14:02,090

318
00:14:02,090 --> 00:14:03,180
Kuwakumbusha yangu ya jina lako.

319
00:14:03,180 --> 00:14:03,470
>> MWANAFUNZI: Kurt.

320
00:14:03,470 --> 00:14:04,070
>> JASON HIRSCHHORN: Kurt.

321
00:14:04,070 --> 00:14:04,480
>> MWANAFUNZI: Ndiyo.

322
00:14:04,480 --> 00:14:04,920
>> JASON HIRSCHHORN: Kwa nini?

323
00:14:04,920 --> 00:14:07,230
>> MWANAFUNZI: Kwa sababu ripoti ya kwanza ni
sifuri, sisi kuanza kuhesabu katika sifuri.

324
00:14:07,230 --> 00:14:08,480
>> JASON HIRSCHHORN: Hivyo sisi kuanza
kuhesabu katika sifuri.

325
00:14:08,480 --> 00:14:09,580
Hiyo ni kweli kabisa.

326
00:14:09,580 --> 00:14:12,340
Hii ni sehemu ya utata na safari mapenzi
wewe juu, hasa wakati uko

327
00:14:12,340 --> 00:14:14,900
kujaribu iterate kupitia arrays,
ambayo tutaweza kufanya katika kidogo.

328
00:14:14,900 --> 00:14:15,980
Sisi kuanza kuhesabu katika sifuri.

329
00:14:15,980 --> 00:14:19,170
Hivyo kama nataka kutaja kwanza
sanduku, siyo sanduku moja.

330
00:14:19,170 --> 00:14:22,290
Kwa bahati mbaya, ni sanduku sifuri.

331
00:14:22,290 --> 00:14:26,460
moja ya pili ni sanduku moja, na katika hii
kesi, moja ya tatu ni sanduku mbili.

332
00:14:26,460 --> 00:14:28,700
>> Nini kuhusu sanduku tatu?

333
00:14:28,700 --> 00:14:30,670
Ambapo ni sanduku tatu?

334
00:14:30,670 --> 00:14:34,750
Au kama nataka kufanya alama, bracket
tatu, karibu bracket, nini hiyo?

335
00:14:34,750 --> 00:14:37,650

336
00:14:37,650 --> 00:14:39,760
Hivyo alisema tabia null.

337
00:14:39,760 --> 00:14:41,600
Mawazo yoyote nyingine?

338
00:14:41,600 --> 00:14:44,590
Je, ni alama ya mabano mabano tatu?

339
00:14:44,590 --> 00:14:48,045
>> MWANAFUNZI: Ni kweli haina kuwepo kwa sababu
wewe tu kuelezwa kama alama,

340
00:14:48,045 --> 00:14:49,370
bracket tatu.

341
00:14:49,370 --> 00:14:51,400
>> JASON HIRSCHHORN: Hivyo unaweza kusema
haina kweli zipo.

342
00:14:51,400 --> 00:14:54,230
Katika baadhi ya matukio, wakati sisi ni kushughulika na
masharti, kwa ujumla tutaweza kuweka null

343
00:14:54,230 --> 00:14:54,790
tabia mwishoni.

344
00:14:54,790 --> 00:14:56,100
Tutaweza kupata kwamba katika pili.

345
00:14:56,100 --> 00:15:01,020
Lakini katika kesi hii, kuna
hakuna sanduku ya tatu hapa.

346
00:15:01,020 --> 00:15:06,390
Hivyo sanduku mwisho katika safu yoyote
ni ukubwa bala 1.

347
00:15:06,390 --> 00:15:11,310
Hivyo kama tuna safu ya n kawaida,
sanduku ya kwanza ni katika sifuri, moja ya mwisho ni

348
00:15:11,310 --> 00:15:12,700
saa n bala 1.

349
00:15:12,700 --> 00:15:14,970
Na katika kesi hii, haipo.

350
00:15:14,970 --> 00:15:17,970
Kuna kitu hapa katika
kumbukumbu lakini siyo yetu.

351
00:15:17,970 --> 00:15:18,460
Sisi si wenyewe yake.

352
00:15:18,460 --> 00:15:19,570
Sisi si kuuliza kwa ajili yake.

353
00:15:19,570 --> 00:15:22,606
Hivyo kama sisi kujaribu kupata huduma hiyo, ambayo tutaweza
kufanya katika kidogo, sisi ni pengine kwenda

354
00:15:22,606 --> 00:15:24,970
kupata katika shida.

355
00:15:24,970 --> 00:15:29,180
>> Katika kesi hiyo, mimi nina initializing yangu
safu na vigezo tatu.

356
00:15:29,180 --> 00:15:36,195
Sisi ni kuweka katika sanduku moja sifuri, wawili
katika sanduku moja, na tatu katika sanduku mbili.

357
00:15:36,195 --> 00:15:39,280
Je, mtu yeyote kuwa na maswali yoyote
kuhusu initializing safu?

358
00:15:39,280 --> 00:15:44,540

359
00:15:44,540 --> 00:15:46,970
>> Hivyo sisi akaenda juu ya hii tu sasa.

360
00:15:46,970 --> 00:15:52,725
Alama, bracket tatu, karibu bracket,
kwamba haipo.

361
00:15:52,725 --> 00:15:58,130
Sisi ni sifuri indexed katika sayansi ya kompyuta,
hivyo sisi kuanza kuhesabu katika sifuri.

362
00:15:58,130 --> 00:16:01,860
sanduku mwisho inapatikana kwetu, ni
sanduku ya tatu, lakini ni kuitwa sanduku

363
00:16:01,860 --> 00:16:03,110
namba mbili.

364
00:16:03,110 --> 00:16:05,790

365
00:16:05,790 --> 00:16:09,710
>> Chini chini, hii ni mbadala
njia ya initializing arrays.

366
00:16:09,710 --> 00:16:13,410
Hivyo badala ya kujenga safu moja
line, kujaza sanduku ya kwanza, basi

367
00:16:13,410 --> 00:16:17,070
sanduku ya pili, basi sanduku ya tatu,
unaweza kufanya hivyo wote katika mstari mmoja.

368
00:16:17,070 --> 00:16:19,040
Hivyo katika mstari kwamba, wote wawili arrays.

369
00:16:19,040 --> 00:16:23,460
Hii inajenga huo halisi safu kama
nini sisi aliumba hapa hapa, lakini ni

370
00:16:23,460 --> 00:16:24,710
tu gani katika mstari mmoja.

371
00:16:24,710 --> 00:16:29,740

372
00:16:29,740 --> 00:16:31,360
>> Sasa tuna umba safu yetu.

373
00:16:31,360 --> 00:16:34,100
Kawaida mara moja kujenga safu, wewe
wanataka kufanya kitu kwa hayo, kama

374
00:16:34,100 --> 00:16:38,430
hiyo ni kujaza au kupata mambo ya nje ya ni
na magazeti yao nje kwenye screen.

375
00:16:38,430 --> 00:16:42,270
Katika kesi hii, sisi ni kwenda kupitia wetu
alama safu, ambayo sisi initialized juu ya

376
00:16:42,270 --> 00:16:44,740
mstari wa kwanza hapa katika kijivu.

377
00:16:44,740 --> 00:16:49,600
Na kisha juu ya mstari wa pili, sisi kuanza
iterating kupitia safu.

378
00:16:49,600 --> 00:16:52,640
Je, mtu yeyote una maswali yoyote kuhusu
muundo wa kwa kitanzi?

379
00:16:52,640 --> 00:16:55,250

380
00:16:55,250 --> 00:16:56,400
>> Hivyo hii ni kwa kitanzi.

381
00:16:56,400 --> 00:16:59,530
Tuna hali yetu ya awali, na kisha
hali yetu ya mwisho, na kisha sisi

382
00:16:59,530 --> 00:17:01,160
iterate, i, kila kitanzi.

383
00:17:01,160 --> 00:17:05,579
Na katika braces curly katika hii kwa
kitanzi, nini kinatokea kama ningekuwa na kukimbia

384
00:17:05,579 --> 00:17:06,290
mpango huu?

385
00:17:06,290 --> 00:17:10,410
Mtu yeyote anaweza kuniambia nini tunataka kupata?

386
00:17:10,410 --> 00:17:11,589
[? Matu? ?]

387
00:17:11,589 --> 00:17:13,819
>> Matu: Magazeti ya alama zote
juu ya kila mstari.

388
00:17:13,819 --> 00:17:14,900
Ingekuwa alama ya magazeti ya kila
juu ya line tofauti.

389
00:17:14,900 --> 00:17:16,300
>> JASON HIRSCHHORN: Ni nini hasa
itakuwa ni ya magazeti?

390
00:17:16,300 --> 00:17:19,790
>> MWANAFUNZI: Itakuwa magazeti moja,
kisha mbili, kisha tatu.

391
00:17:19,790 --> 00:17:20,235
>> JASON HIRSCHHORN: Hasa.

392
00:17:20,235 --> 00:17:23,490
Ingekuwa magazeti moja, kisha mbili, kisha
tatu, kila juu ya mistari tofauti, kwa sababu

393
00:17:23,490 --> 00:17:27,810
tunakwenda kupitia safu na utasikia
kuona kwamba pili, printf

394
00:17:27,810 --> 00:17:29,275
kauli, alama i.

395
00:17:29,275 --> 00:17:32,880
Kadhalika raundi ya kwanza kupitia yetu kwa ajili ya
kitanzi, i sawa na sifuri, ambayo ina maana sisi ni

396
00:17:32,880 --> 00:17:34,640
kupata thamani katika alama sifuri -

397
00:17:34,640 --> 00:17:36,900
ambayo kama sisi kurudi nyuma kwa
mchoro wetu, ni moja -

398
00:17:36,900 --> 00:17:38,630
na kujaza -

399
00:17:38,630 --> 00:17:39,700
oh, inasema c.

400
00:17:39,700 --> 00:17:41,680
Kwamba lazima% d.

401
00:17:41,680 --> 00:17:43,970
Nami kurekebisha kwamba katika kidogo wakati
Mimi mkono kwamba nje kwenu guys.

402
00:17:43,970 --> 00:17:48,670
Lakini sisi ni kuwasilisha integer hivyo
lazima% d haki hapa, si% c.

403
00:17:48,670 --> 00:17:50,340
Je, ni kwa ajili ya% c?

404
00:17:50,340 --> 00:17:50,790
>> MWANAFUNZI: Tabia.

405
00:17:50,790 --> 00:17:52,680
>> JASON HIRSCHHORN: Tabia, hasa.

406
00:17:52,680 --> 00:17:53,690
Je, ni mtu mwingine?

407
00:17:53,690 --> 00:17:56,260
Kama hutaki kufanya% d kwa
integer, nini kingine unaweza kufanya nini?

408
00:17:56,260 --> 00:17:57,000
>> MWANAFUNZI: i.

409
00:17:57,000 --> 00:17:59,180
>> JASON HIRSCHHORN:% i, hasa.

410
00:17:59,180 --> 00:18:01,660
Hivyo maswali yoyote kuhusu iterating
kupitia safu?

411
00:18:01,660 --> 00:18:05,500

412
00:18:05,500 --> 00:18:07,800
Hivyo kile kinachotokea kama sisi kufanya hili?

413
00:18:07,800 --> 00:18:10,290
Badala ya kufanya i ni chini ya
tatu, sisi gani i ni chini

414
00:18:10,290 --> 00:18:11,390
zaidi au sawa na tatu.

415
00:18:11,390 --> 00:18:13,420
Nini kinatokea wakati sisi kukimbia kanuni hii?

416
00:18:13,420 --> 00:18:17,510

417
00:18:17,510 --> 00:18:18,940
Ndiyo, Annie?

418
00:18:18,940 --> 00:18:22,030
>> MWANAFUNZI: Wao wanaenda magazeti nje
weird mambo kwenye mstari wa nne.

419
00:18:22,030 --> 00:18:23,850
>> JASON HIRSCHHORN: Hivyo wewe alisema, ni
kwenda magazeti nje mambo weird juu ya

420
00:18:23,850 --> 00:18:24,390
nne mstari?

421
00:18:24,390 --> 00:18:25,750
Je, mtu yeyote kuwa na jibu
kwa swali lake?

422
00:18:25,750 --> 00:18:28,940

423
00:18:28,940 --> 00:18:33,160
Hivyo ni tabia mbaya kwamba wakati
sisi kupata -

424
00:18:33,160 --> 00:18:36,700
kadhalika duru ya nne kupitia kwa wetu
kitanzi, kama wewe mawazo, Annie,

425
00:18:36,700 --> 00:18:39,430
utakuwa ni alama ya mabano ya tatu, ambayo
tumekuwa tayari figured haina

426
00:18:39,430 --> 00:18:41,990
zipo, na sisi ni kwenda kujaribu
na kupata kwamba, magazeti

427
00:18:41,990 --> 00:18:43,350
nje, kutumia baadhi ya njia.

428
00:18:43,350 --> 00:18:46,060
Hivyo kompyuta pengine
kumkasirikia sana kwetu.

429
00:18:46,060 --> 00:18:46,760
Uko sahihi kabisa.

430
00:18:46,760 --> 00:18:48,830
>> Ni wanaweza kuacha mpango kabisa.

431
00:18:48,830 --> 00:18:52,222
Huenda magazeti nje kitu
kweli weird.

432
00:18:52,222 --> 00:18:53,420
Huwezi kusema kwa uhakika.

433
00:18:53,420 --> 00:18:56,210
Ni tabia mbaya hivyo itabidi pengine kupata wazimu katika
wewe na tu kuacha mara moja.

434
00:18:56,210 --> 00:19:00,100
>> Lakini hii ni makosa ya kawaida itabidi
ambapo wewe ni mbali tu na mmoja katika

435
00:19:00,100 --> 00:19:05,110
mwisho, na hii ni mdudu kwamba mapenzi
pigo ninyi katika coding yako.

436
00:19:05,110 --> 00:19:09,350

437
00:19:09,350 --> 00:19:14,150
Moja ya njia ya mimi kama kufanya ni tu juu ya
ubao mweupe, kupitia kila iteration

438
00:19:14,150 --> 00:19:18,190
ya kitanzi kwenye mkono au kwenye karatasi ya kuona
nini kinatokea, na kisha

439
00:19:18,190 --> 00:19:20,440
ujumla kutambua, oh kusubiri, mimi lazima si
wamekwenda chini ya au

440
00:19:20,440 --> 00:19:20,870
sawa na tatu.

441
00:19:20,870 --> 00:19:24,730
Mimi lazima kusimamishwa saa mbili, ambayo ni
kile kinachotokea kama hali yako ni chini ya

442
00:19:24,730 --> 00:19:26,206
ya tatu.

443
00:19:26,206 --> 00:19:29,120
Maswali yoyote hadi sasa?

444
00:19:29,120 --> 00:19:31,010
Tamu.

445
00:19:31,010 --> 00:19:33,360
>> Hivyo wote wana kompyuta yako wazi.

446
00:19:33,360 --> 00:19:36,760
Tunakwenda kukupa 02:58
dakika kuandika mpango kwamba

447
00:19:36,760 --> 00:19:40,460
inajenga safu moja na integers
kwa njia ya tano na kisha Prints nje ya kila aina

448
00:19:40,460 --> 00:19:41,720
integer kwenye mstari mpya.

449
00:19:41,720 --> 00:19:44,330

450
00:19:44,330 --> 00:19:46,000
Na kama una maswali yoyote,
kunyanyua mkono wako.

451
00:19:46,000 --> 00:19:48,140
Mimi nina furaha kuja na.

452
00:19:48,140 --> 00:19:50,630
Kama nilivyosema, hebu kuchukua tatu
dakika ya kuandika hii.

453
00:19:50,630 --> 00:20:41,300

454
00:20:41,300 --> 00:20:45,110
Kila mtu ni sawa kama mimi kwenda
dirisha jipya na karibu hii?

455
00:20:45,110 --> 00:22:13,420

456
00:22:13,420 --> 00:22:15,520
>> Samahani kama si alikuwa na nafasi ya
kumaliza, lakini sisi ni kwenda kufanya hivyo

457
00:22:15,520 --> 00:22:17,310
pamoja hivi sasa.

458
00:22:17,310 --> 00:22:23,640
Hivyo hadi kwenye screen, mimi ni pamoja #
cs50.h, # stdio.h pamoja.

459
00:22:23,640 --> 00:22:26,090
Je, mtu kuniambia nini
wale mistari mbili kufanya?

460
00:22:26,090 --> 00:22:32,250

461
00:22:32,250 --> 00:22:33,155
Michael?

>> MWANAFUNZI: Wao ni maktaba
kwamba CS50 kufanywa na kwamba Steve ina

kuokolewa kwa wewe kutumia kwa
kufanya maisha yako rahisi.

464
00:22:44,210 --> 00:22:46,820
>> JASON HIRSCHHORN: Hivyo wewe walisema
pamoja na maktaba, mmoja kwamba CS50

465
00:22:46,820 --> 00:22:51,230
alifanya, cs50.h, na moja ambayo ni
tu ya kiwango, huja na

466
00:22:51,230 --> 00:22:53,510
C mfuko, stdio.h.

467
00:22:53,510 --> 00:22:54,890
Ni nini maana ni pamoja na
maktaba, ingawa?

468
00:22:54,890 --> 00:22:55,770

>> MWANAFUNZI: Ni hufanya hivyo kwamba unaweza
kutumia maneno ya kanuni fulani ya kuwa na

nipe mfano?

ni moja unaweza kutumia.

00:23:11,860 --> 00:23:14,680
Hivyo alisema printf ni mmoja wa wale
kazi ambapo badala ya kuwa na

475
00:23:14,680 --> 00:23:19,840
kuandika printf juu yako mwenyewe, printf ni
pamoja na kweli katika stdio.h, hivyo

476
00:23:19,840 --> 00:23:22,010
anaweza tu matumizi yake na kudhani
kwamba itakuwa kazi.

477
00:23:22,010 --> 00:23:28,270
Katika stdio.h, kama wewe kufunguliwa hadi kwamba faili,
itakuwa ni pamoja na jinsi gani printf

478
00:23:28,270 --> 00:23:31,620
matendo, wote wa kanuni kwa ajili ya printf?

479
00:23:31,620 --> 00:23:33,105
Mbona kutikisa kichwa yako?

faili header tu ni pamoja na
tamko kazi.

483
00:23:39,680 --> 00:23:42,950
Hivyo kimsingi, wakati wewe kukusanya hii,
hit kufanya Count, ambayo tutaweza kufanya katika

484
00:23:42,950 --> 00:23:48,070
pili, mkusanyaji anajua kwamba, kama
wewe kutumia printf, printf lipo.

485
00:23:48,070 --> 00:23:49,370
Ni kwenda kuelezwa mahali fulani.

486
00:23:49,370 --> 00:23:51,200
Siyo tatizo kwa wewe kutumia.

487
00:23:51,200 --> 00:23:55,490
Na kisha baadaye, utakuwa ni pamoja na
ndio na zeros kwamba kweli yana

utekelezaji printf na
kuunganisha yao na kanuni yako.

489
00:23:58,360 --> 00:24:01,935
Jinsi gani unaweza kuhakikisha ni pamoja na
ndio na zeros kwa kusema, kupata kamba?

490
00:24:01,935 --> 00:24:05,670

491

493
00:24:07,830 --> 00:24:11,110
Hivyo kwamba anasema kupata kamba lipo,
tamko kazi.

494
00:24:11,110 --> 00:24:15,410
Lakini basi ndio na zeros, binary
faili kwamba kweli ni pamoja na

495

utekelezaji wa kamba wa kupata?

496
00:24:17,370 --> 00:24:19,310

628
00:28:59,880 --> 00:29:02,240
>> MWANAFUNZI: Kwa sababu doa tano
ni kwa ajili ya tabia null.

629
00:29:02,240 --> 00:29:04,070
>> JASON HIRSCHHORN: Hivyo doa tano
ni kwa ajili ya tabia null.

630
00:29:04,070 --> 00:29:07,130
Hivyo kama ningekuwa na kukimbia strlen juu ya
hii, ingekuwa nipe nne.

631
00:29:07,130 --> 00:29:07,850
Kusahihisha.

632
00:29:07,850 --> 00:29:11,640
Na safu, ingawa, kama ningekuwa
initialize safu hii, jinsi wengi nafasi

633
00:29:11,640 --> 00:29:13,444
ingekuwa mimi kuwa na kuomba?

634
00:29:13,444 --> 00:29:13,821
>> MWANAFUNZI: Tano.

635
00:29:13,821 --> 00:29:14,200
>> JASON HIRSCHHORN: Tano.

636
00:29:14,200 --> 00:29:17,650
Ningependa kuuliza kwa ajili ya tano, lakini siwezi
tu kuweka herufi nne katika hapa

637
00:29:17,650 --> 00:29:19,750
kwa sababu mimi haja ya kuweka kwamba null
Terminator ya mwisho.

638
00:29:19,750 --> 00:29:25,260
Hivyo sisi ni kwenda kuandika katika "ohai" na
kuweka Terminator null katika mwishoni.

639
00:29:25,260 --> 00:29:31,820

640
00:29:31,820 --> 00:29:34,940
Tutaweza kusema hii ni kamba
s sawa na hii.

641
00:29:34,940 --> 00:29:36,610
Je, ni s mabano sifuri?

642
00:29:36,610 --> 00:29:40,210

643
00:29:40,210 --> 00:29:41,550
s mabano sifuri, Annie?

644
00:29:41,550 --> 00:29:41,950
>> MWANAFUNZI: O.

645
00:29:41,950 --> 00:29:45,400
>> JASON HIRSCHHORN: O, hasa.
s mabano moja?

646
00:29:45,400 --> 00:29:48,200
s mabano tano?

647
00:29:48,200 --> 00:29:52,670

648
00:29:52,670 --> 00:29:53,955
s mabano tano?

649
00:29:53,955 --> 00:29:54,740
>> MWANAFUNZI: Je, si zipo.

650
00:29:54,740 --> 00:29:55,040
>> JASON HIRSCHHORN: Je, si zipo.

651
00:29:55,040 --> 00:29:57,050
Hasa haki.

652
00:29:57,050 --> 00:29:57,940
Baridi.

653
00:29:57,940 --> 00:30:03,120
Maswali yoyote kuhusu uelewa
masharti kama arrays ya wahusika?

654
00:30:03,120 --> 00:30:03,870
OK, basi.

655
00:30:03,870 --> 00:30:05,440
Moja zaidi ya mpango kwa nyie.

656
00:30:05,440 --> 00:30:09,190
Kuandika mpango kwamba anauliza mtumiaji
kwa kamba kisha Prints nje ya kila aina

657
00:30:09,190 --> 00:30:11,880
tabia kwenye mstari mpya.

658
00:30:11,880 --> 00:30:14,160
Basi hebu chukua dakika tatu ya kuandika
mpango huu, na kisha tutaweza kanuni ni

659
00:30:14,160 --> 00:30:15,410
kama kundi.

660
00:30:15,410 --> 00:31:04,730

661
00:31:04,730 --> 00:31:04,830
>> Sorry.

662
00:31:04,830 --> 00:31:06,470
Je, unahitaji kuona hii?

663
00:31:06,470 --> 00:31:07,410
>> MWANAFUNZI: Hapana

664
00:31:07,410 --> 00:31:08,660
>> JASON HIRSCHHORN: OK.

665
00:31:08,660 --> 00:31:36,390

666
00:31:36,390 --> 00:31:40,605
Hebu kuchukua dakika moja zaidi na kanuni hii,
au angalau kupata kuanza juu yake.

667
00:31:40,605 --> 00:32:13,900

668
00:32:13,900 --> 00:32:17,020
>> Hivyo unaweza kuendelea kufanya kazi, lakini nina kwenda
kuanza kwenda kwa njia hiyo.

669
00:32:17,020 --> 00:32:22,560
Hivyo kama kabla, nina juu ya screen
# Pamoja cs50.h, # stdio.h pamoja.

00:32:24,020 --> 00:32:28,880
Ndani ya braces kuu ya curly, nina
mbili maoni, pseudocode.

672
00:32:28,880 --> 00:32:30,980
Moja ni kuomba kwa ajili ya kamba kutoka mtumiaji.

673
00:32:30,980 --> 00:32:33,900
pili ni magazeti nje ya kila aina
tabia kwenye mstari mpya.

674
00:32:33,900 --> 00:32:39,780
Hivyo Anna, unaweza kunipa kuuliza
kwa kamba kutoka kwa mtumiaji?

675
00:32:39,780 --> 00:32:41,970
>> MWANAFUNZI: printf.

676

Hivyo nina kwenda kupata kamba na
Mimi nina kwenda kuokoa ni katika nini?

695
00:33:19,000 --> 00:33:21,830
Nini kutofautiana kuitwa

Hasa.

700
00:33:27,200 --> 00:33:30,080
Next kitu tunataka ni magazeti nje
kila tabia kwenye mstari mpya.

701

Ambaye anaweza nipe kwamba kanuni?

702

Kwa bahati mbaya, nina
kusema ni juu yenu.

kurekebisha jambo moja kwanza, na kisha kukimbia
yake, na kisha kuona makosa sisi kupata.

785

Inatarajiwa semicolon.

789

Na mimi bado kupata
makosa katika mstari huu.

790

Hivyo hakunipa kosa kusema ni
haelewi nini strlen ni,

791
00:36:25,270 --> 00:36:28,980
lakini ni kunipa makosa juu ya hii
line, hivyo kile kingine ni kosa?

792
00:36:28,980 --> 00:36:29,690
Alama ya?

793
00:36:29,690 --> 00:36:30,940
Marcus.

794
00:36:30,940 --> 00:36:32,570
>> MWANAFUNZI: Je, una kuondoa
pili int tamko?

795
00:36:32,570 --> 00:36:34,990
>> JASON HIRSCHHORN: Ondoa
int pili.

796
00:36:34,990 --> 00:36:35,710
Hebu jaribu hii.

797
00:36:35,710 --> 00:36:37,600
Sasa wazi terminal.

798
00:36:37,600 --> 00:36:40,130
Kufanya uchawi.

799
00:36:40,130 --> 00:36:40,490
Makosa.

800
00:36:40,490 --> 00:36:42,890
Inamuunga kutangaza maktaba
kazi strlen.

801
00:36:42,890 --> 00:36:44,270
Hivyo sasa hatuwezi kuona kwamba makosa.

802
00:36:44,270 --> 00:36:45,760
Tunahitaji nini kwa pamoja?

803
00:36:45,760 --> 00:36:46,660
>> MWANAFUNZI: String.h.

804
00:36:46,660 --> 00:36:51,880
>> JASON HIRSCHHORN: Ni pamoja string.h,
tutaweza kufanya ni pamoja # string.h kwa juu

805
00:36:51,880 --> 00:36:52,920
ya screen.

806
00:36:52,920 --> 00:36:55,450
Hebu kuokoa, kufanya uchawi.

807
00:36:55,450 --> 00:36:56,970
Sasa ulioandaliwa.

808
00:36:56,970 --> 00:37:01,970
Hivyo tena, mambo ya sisi zinahitajika
kumbuka mstari 12 katika kitanzi wetu kwa wakati

809
00:37:01,970 --> 00:37:08,010
sisi ni kuiandaa, int i = 0,
urefu = strlen (s).

810
00:37:08,010 --> 00:37:09,350
>> Huu ni mkakati wa ajabu.

811
00:37:09,350 --> 00:37:12,590
mtindo wa hii ni kubwa,
mpango wa hii ni kubwa.

812
00:37:12,590 --> 00:37:15,620
Tunaweza kwenda katika sababu hizo baadaye,
lakini njia hii tu haja ya simu

813
00:37:15,620 --> 00:37:19,040
strlen mara moja badala ya kila moja
wakati wewe kukimbia kwa njia ya kitanzi.

814
00:37:19,040 --> 00:37:22,255
Hata hivyo, unahitaji kutumia comma kuna
na huna haja ya int tena.

815
00:37:22,255 --> 00:37:24,180
Kama wewe ni kutangaza wote wale
vigezo pamoja, ninyi

816
00:37:24,180 --> 00:37:26,850
hawana haja int tena.

817
00:37:26,850 --> 00:37:29,820
Na kisha kama wewe ni kwenda kutumia strlen,
ambayo ni mwingine maktaba

818
00:37:29,820 --> 00:37:33,560
Kazi si pamoja katika
stdio.h au cs50.h, kufanya

819
00:37:33,560 --> 00:37:35,310
uhakika ni pamoja string.h.

820
00:37:35,310 --> 00:37:35,900
Kurt?

821
00:37:35,900 --> 00:37:39,085
>> MWANAFUNZI: Hivyo basi kama wewe hawana haja ya
kusema nini aina urefu ni, je, hiyo

822
00:37:39,085 --> 00:37:40,290
maana ina kuwa int?

823
00:37:40,290 --> 00:37:41,930
Unaweza kuwa na mbili tofauti
aina huko?

824
00:37:41,930 --> 00:37:43,290
>> JASON HIRSCHHORN: Hivyo unaweza
na aina mbili tofauti.

825
00:37:43,290 --> 00:37:45,730
Urefu ni int hapa, ingawa.

826
00:37:45,730 --> 00:37:48,590
Urefu ni int sababu ni comma
na kisha kitu kimoja.

827
00:37:48,590 --> 00:37:50,460
>> MWANAFUNZI: Hivyo inadhaniwa kwamba ni kwenda
kuwa sawa kama moja ya kwanza?

828
00:37:50,460 --> 00:37:52,423
>> JASON HIRSCHHORN: Hasa.

829
00:37:52,423 --> 00:37:54,970
Sisi siyo kwenda kufanya hili sasa, lakini
unaweza ni pamoja na vigezo mbili juu ya

830
00:37:54,970 --> 00:37:57,080
huo line kutumia data aina moja.

831
00:37:57,080 --> 00:38:01,415
Hivyo int x, y ingekuwa kujenga
mbili vigezo.

832
00:38:01,415 --> 00:38:05,830

833
00:38:05,830 --> 00:38:10,770
Hivyo int x, y, kama sisi kufanya kwamba, ni inatoa
mimi isiyotumika kutofautiana x na y kwa sababu

834
00:38:10,770 --> 00:38:12,020
hatuwezi kutumia yao.

835
00:38:12,020 --> 00:38:17,950

836
00:38:17,950 --> 00:38:21,650
Hivyo kuweka utupu kabla ni
dhana hila kama huna kutumia

837
00:38:21,650 --> 00:38:22,810
kitu, kwa matumizi yake.

838
00:38:22,810 --> 00:38:26,300
Lakini kama unaweza kuona, mimi kuunda x na y
juu ya mstari huo na comma.

839
00:38:26,300 --> 00:38:28,450
Ni kujenga integers mbili
haki huko.

840
00:38:28,450 --> 00:38:31,560
Hivyo ndiyo, inawezekana kabisa kujenga
mambo mawili juu ya mstari huo

841
00:38:31,560 --> 00:38:33,720
kutengwa kwa koma.

842
00:38:33,720 --> 00:38:35,470
Hebu kujikwamua wale, ingawa.

843
00:38:35,470 --> 00:38:36,370
>> Hivyo kuna Spell.

844
00:38:36,370 --> 00:38:39,200
Asante kwa guys coding ni kwa ajili yetu.

845
00:38:39,200 --> 00:38:43,040
Hebu kufanya hivyo ni moja muda zaidi, kukimbia.

846
00:38:43,040 --> 00:38:44,580
Nipe kamba.

847
00:38:44,580 --> 00:38:45,580
[Inaudible], alifanya zaidi ya hayo.

848
00:38:45,580 --> 00:38:47,910
Nini kamba?

849
00:38:47,910 --> 00:38:48,250
>> MWANAFUNZI: Hello.

850
00:38:48,250 --> 00:38:50,110
>> JASON HIRSCHHORN: Hello.

851
00:38:50,110 --> 00:38:52,810
H-E-L-L-O, kila tabia kwenye mstari mmoja.

852
00:38:52,810 --> 00:38:53,700
Inaonekana ni kubwa.

853
00:38:53,700 --> 00:38:54,750
Hebu kukimbia tena.

854
00:38:54,750 --> 00:38:56,050
Daima kwenda kuangalia
kwa kona ya kesi.

855
00:38:56,050 --> 00:38:57,750
Nini nzuri kona kesi kuangalia?

856
00:38:57,750 --> 00:39:00,250

857
00:39:00,250 --> 00:39:00,890
>> MWANAFUNZI: idadi?

858
00:39:00,890 --> 00:39:02,240
>> JASON HIRSCHHORN: idadi.

859
00:39:02,240 --> 00:39:06,580
Hivyo mimi itabidi kuweka katika 1, na ni Prints nje 1.

860
00:39:06,580 --> 00:39:08,970
Siyo kuuliza kwa barua, hivyo
inaonekana kama kazi ya namba.

861
00:39:08,970 --> 00:39:09,890
Nzuri kona kesi ya kuangalia.

862
00:39:09,890 --> 00:39:11,740
Nini mwingine kona nzuri
kesi ya kuangalia?

863
00:39:11,740 --> 00:39:12,420
>> MWANAFUNZI: kamba tupu.

864
00:39:12,420 --> 00:39:12,910
>> JASON HIRSCHHORN: Hm?

865
00:39:12,910 --> 00:39:13,880
>> MWANAFUNZI: Kama kamba tupu.

866
00:39:13,880 --> 00:39:14,400
>> JASON HIRSCHHORN: Tupu kamba.

867
00:39:14,400 --> 00:39:16,730
Hivyo basi si kuweka kitu chochote.

868
00:39:16,730 --> 00:39:18,660
Na nini anapata kuchapishwa nje?

869
00:39:18,660 --> 00:39:19,090
>> MWANAFUNZI: Hakuna.

870
00:39:19,090 --> 00:39:19,870
>> JASON HIRSCHHORN: Hakuna.

871
00:39:19,870 --> 00:39:20,555
Inaonekana kama ni kazi.

872
00:39:20,555 --> 00:39:23,790
Unaweza kujaribu kesi kona zaidi, lakini
ujumla idadi, data tofauti ni

873
00:39:23,790 --> 00:39:26,160
kubwa ya kujaribu, kama vile ni kitu.

874
00:39:26,160 --> 00:39:29,180
Chochote, sifuri, negatives ni daima
mambo makubwa ya kujaribu na mambo

875
00:39:29,180 --> 00:39:33,140
lazima mtihani, mambo hakika tutaweza mtihani
Angalia kwa ajili na 50 kwa ajili ya mtihani.

876
00:39:33,140 --> 00:39:34,720
Maswali yoyote kuhusu spell.c?

877
00:39:34,720 --> 00:39:37,752

878
00:39:37,752 --> 00:39:39,310
>> OK, hebu kichwa nyuma.

879
00:39:39,310 --> 00:39:42,420
Mimi moja zaidi ya mpango
kwa nyie kuandika.

880
00:39:42,420 --> 00:39:44,700
Ni wito students.c.

881
00:39:44,700 --> 00:39:49,020
Hii ni programu ambayo anauliza mtumiaji kwa ajili ya
tano majina, kisha nasibu akiamua

882
00:39:49,020 --> 00:39:51,600
na Prints nje moja ya majina.

883
00:39:51,600 --> 00:39:54,840
Mpango huu ni kidogo zaidi
kushiriki kuliko mawili ya mwisho sisi aliandika,

884
00:39:54,840 --> 00:39:58,080
hivyo kwa nini sisi kuchukua dakika tano
Kanuni ni mmoja mmoja, na basi tutaweza

885
00:39:58,080 --> 00:40:00,130
kanuni ni kama kundi.

886
00:40:00,130 --> 00:40:03,795
>> Mpango huu pia kuhusisha baadhi ya mambo
unaweza kuwa na kuona mbele, hivyo kama

887
00:40:03,795 --> 00:40:06,390
una swali kuhusu, jinsi ya kufanya
Mimi kufanya hivyo, kuinua mkono wako.

888
00:40:06,390 --> 00:40:08,530
Mimi itabidi kuja juu na kumweka wewe
katika mwelekeo sahihi.

889
00:40:08,530 --> 00:40:10,820
Lakini sisi ni pia kufanya hivyo kwa sababu hii
itakuwa njia nzuri ya kuanzisha baadhi ya

890
00:40:10,820 --> 00:40:12,070
mada ambazo ni gumu.

891
00:40:12,070 --> 00:44:14,600

892
00:44:14,600 --> 00:44:15,560
>> Hivyo ni kazi, haki?

893
00:44:15,560 --> 00:44:17,580
>> MWANAFUNZI: Yeah.

894
00:44:17,580 --> 00:44:19,180
>> JASON HIRSCHHORN: Kila wewe kurejea katika
tatizo kuweka, kuna njia nyingi za kufanya

895
00:44:19,180 --> 00:44:20,790
hilo, lakini baadhi ni zaidi
kifahari zaidi kuliko wengine.

896
00:44:20,790 --> 00:44:29,000

897
00:44:29,000 --> 00:44:31,110
Hebu dive in

898
00:44:31,110 --> 00:44:32,880
# Pamoja cs50.h.

899
00:44:32,880 --> 00:44:34,250
# Stdio.h pamoja.

900
00:44:34,250 --> 00:44:37,240
int kuu utupu, curly braces.

901
00:44:37,240 --> 00:44:39,430
Ndani ya braces curly,
Nina maoni mawili.

902
00:44:39,430 --> 00:44:41,500
moja ya kwanza, kuuliza
mtumiaji kwa ajili ya majina matano.

903
00:44:41,500 --> 00:44:46,580
moja ya pili ni, nasibu kuchagua
na magazeti nje moja ya majina.

904
00:44:46,580 --> 00:44:50,250
Basi hebu kufanya moja ya kwanza, kuuliza
mtumiaji kwa ajili ya majina matano.

905
00:44:50,250 --> 00:44:53,730
Ambaye aliuliza mtumiaji kwa ajili ya majina matano
na inaweza kuniambia jinsi ya kufanya hivyo?

906
00:44:53,730 --> 00:44:56,760

907
00:44:56,760 --> 00:44:58,570
Watu wawili tu alifanya sehemu ya kwanza.

908
00:44:58,570 --> 00:45:00,150
Watu watatu alifanya sehemu ya kwanza.

909
00:45:00,150 --> 00:45:00,670
Nne, tano.

910
00:45:00,670 --> 00:45:03,140
Tom, jinsi gani unaweza kufanya hivyo?

911
00:45:03,140 --> 00:45:09,940
>> MWANAFUNZI: Wewe ingekuwa kutangaza kamba
na kisha jina, bracket tano.

912
00:45:09,940 --> 00:45:12,070
>> JASON HIRSCHHORN: Kamba
jina mabano tano.

913
00:45:12,070 --> 00:45:15,350
Hivyo ni nini mstari huu kufanya,
kamba jina mabano tano?

914
00:45:15,350 --> 00:45:17,800
>> MWANAFUNZI: Wewe ingekuwa kutangaza
safu ya masharti.

915
00:45:17,800 --> 00:45:19,000
>> JASON HIRSCHHORN: Hii ni
safu ya masharti.

916
00:45:19,000 --> 00:45:21,590
Wangapi masharti ni kwenda
walionao katika hapa?

917
00:45:21,590 --> 00:45:22,010
>> MWANAFUNZI: Tano.

918
00:45:22,010 --> 00:45:22,320
>> JASON HIRSCHHORN: Tano.

919
00:45:22,320 --> 00:45:22,660
Bora.

920
00:45:22,660 --> 00:45:26,360
Tunakwenda kuiita Majina sababu
tunakwenda kupata wale nyingi.

921
00:45:26,360 --> 00:45:27,790
OK, ijayo?

922
00:45:27,790 --> 00:45:29,270
>> MWANAFUNZI: Na kisha
kuwa kwa kitanzi -

923
00:45:29,270 --> 00:45:30,060
>> JASON HIRSCHHORN: Kwa kitanzi.

924

Ndani ya braces curly?

937
00:45:50,050 --> 00:45:51,423
>> MWANAFUNZI: Na kisha printf.

>> JASON HIRSCHHORN: i + 1.

955
00:46:29,400 --> 00:46:31,600
>> MWANAFUNZI: Ndiyo.

956
00:46:31,600 --> 00:46:36,440
Na kisha slide ijayo
ni majina mabano i.

957
00:46:36,440 --> 00:46:39,000
>> JASON HIRSCHHORN: Next line
ni majina mabano i.

958
00:46:39,000 --> 00:46:41,360
>> MWANAFUNZI: = kupata kamba.

959
00:46:41,360 --> 00:46:43,460
>> JASON HIRSCHHORN: = Kupata -

960
00:46:43,460 --> 00:46:44,510
mji mkuu wa G-E-T -

961
00:46:44,510 --> 00:46:45,530
kamba.

962
00:46:45,530 --> 00:46:47,800
Oops, sorry.

963
00:46:47,800 --> 00:46:49,050
>> MWANAFUNZI: Open, imefungwa mabano
na kisha -

964
00:46:49,050 --> 00:46:50,940
>> JASON HIRSCHHORN: Open, imefungwa paren.

965
00:46:50,940 --> 00:46:51,030
>> MWANAFUNZI: semicolon.

966
00:46:51,030 --> 00:46:52,500
>> JASON HIRSCHHORN: semicolon.

967
00:46:52,500 --> 00:46:57,545
OK, hivyo initialize safu ya
masharti, majina, na kisha kwenda kwa njia ya

968
00:46:57,545 --> 00:47:02,720
kwa kitanzi, na mara tano magazeti nje ya baadhi ya
haraka kwa mtumiaji na kisha kuhifadhi

969
00:47:02,720 --> 00:47:03,360
tano masharti.

970
00:47:03,360 --> 00:47:08,090
Je, mtu yeyote yoyote
marekebisho ya hili?

971
00:47:08,090 --> 00:47:10,030
Tom, nadhani kila mtu
anakubaliana na wewe.

972
00:47:10,030 --> 00:47:10,880
Inaonekana pretty nzuri.

973
00:47:10,880 --> 00:47:11,660
OK.

974
00:47:11,660 --> 00:47:14,830
Kwa nini wewe kufanya i 1, ingawa?

975
00:47:14,830 --> 00:47:18,000
>> MWANAFUNZI: I mean, hana
kuwa, lakini i 1 hivyo kwamba ni

976
00:47:18,000 --> 00:47:19,700
jina moja kwa jina tano.

977
00:47:19,700 --> 00:47:21,930
Vinginevyo, itakuwa ni jina
sifuri kwa jina nne.

978
00:47:21,930 --> 00:47:24,400
>> JASON HIRSCHHORN: Hivyo wewe alifanya i 1
kwa sababu vinginevyo ingekuwa

979
00:47:24,400 --> 00:47:27,060
kuchapishwa sifuri kwa njia ya nne kwa sababu
kwamba ni jinsi kompyuta kufikiri, lakini binadamu

980
00:47:27,060 --> 00:47:28,530
si kweli kusoma kama hiyo.

981
00:47:28,530 --> 00:47:30,190
Hiyo ni kitu kingine
utasikia kukutana.

982
00:47:30,190 --> 00:47:33,210
Wakati mwingine wakati magazeti nje kitu
kwa mtumiaji, utasikia wanataka kufanya hivyo

983
00:47:33,210 --> 00:47:35,733
kidogo kidogo prettier, na kufanya
i 1 katika kesi hii ni

984
00:47:35,733 --> 00:47:37,430
njia ya kufanya hivyo prettier.

985
00:47:37,430 --> 00:47:41,380
>> Mimi pia kuona mitano mara mbili, kamba jina
ni tano, i ni chini ya miaka mitano.

986
00:47:41,380 --> 00:47:42,430
Najua wapi got tano.

987
00:47:42,430 --> 00:47:44,890
Wewe got ni kutoka kwangu kuwaambia
wewe tano majina.

988
00:47:44,890 --> 00:47:49,000
Lakini kama tulitaka kufanya kanuni
kidogo kidogo imara zaidi, jambo moja sisi

989
00:47:49,000 --> 00:47:53,110
inaweza kufanya ni nje hapa, nje ya int,
tunaweza kufanya kitu kama hii,

990
00:47:53,110 --> 00:47:57,070
# Define, na tunaweza kufanya MAJINA 5.

991
00:47:57,070 --> 00:48:01,580

992
00:48:01,580 --> 00:48:05,390
>> Hivyo kimsingi, popote mimi kuandika mji mkuu
N, mji mkuu wa A, mji mkuu wa M, mji mkuu wa E,

993
00:48:05,390 --> 00:48:08,890
mji mkuu S, kwamba kamba, itakuwa nafasi
kwamba pamoja na 5 katika kanuni.

994
00:48:08,890 --> 00:48:11,530

995
00:48:11,530 --> 00:48:13,445
Au hebu tu kuiita - tutaweza
tu kuiita NUMBER.

996
00:48:13,445 --> 00:48:17,190
Hivyo mimi nina kofia kufafanua kila
NUMBER kuwa 5.

997
00:48:17,190 --> 00:48:22,830
>> Hivyo sasa popote mimi kuwa na idadi 5, mimi
unaweza badala yake pamoja na wote NUMBER kofia.

998
00:48:22,830 --> 00:48:26,880
Na sasa, kama nataka mabadiliko ya idadi ya
ya majina, wote mimi haja ya kufanya ni

999
00:48:26,880 --> 00:48:31,350
line hii moja, line nne, ambapo nina
# Define namba 5, mabadiliko ya kwamba hadi 10,

1000
00:48:31,350 --> 00:48:34,340
au mabadiliko ya kwamba hadi 4.

1001
00:48:34,340 --> 00:48:37,400
Wakati kanuni wako anapata tena, wewe si
kwenda kukumbuka maeneo yote

1002
00:48:37,400 --> 00:48:41,630
kuweka ngapi majina alitaka, na katika
ili kwa wewe si miss mmoja, hii ni

1003
00:48:41,630 --> 00:48:45,490
Njia nzuri ya kufanya hivyo, kupata kitu
juu juu na kisha kutumia tu kwamba maneno

1004
00:48:45,490 --> 00:48:46,400
kila mahali katika kanuni yako.

1005
00:48:46,400 --> 00:48:46,780
Marcus?

1006
00:48:46,780 --> 00:48:49,780
>> MWANAFUNZI: Ni kwamba stylistically preferred
kuliko kimataifa kufafanua

1007
00:48:49,780 --> 00:48:51,270
mara kwa mara n?

1008
00:48:51,270 --> 00:48:53,760
>> JASON HIRSCHHORN: Hivyo ni kwamba
stylistically preferred kuliko kimataifa

1009
00:48:53,760 --> 00:48:54,980
kufafanua n mara kwa mara?

1010
00:48:54,980 --> 00:48:59,036
Hivyo ni kusema unaweza
kufanya, int idadi = 5?

1011
00:48:59,036 --> 00:49:01,300
>> MWANAFUNZI: Je, wana konsonanti
katika C au hakuna?

1012
00:49:01,300 --> 00:49:02,720
>> JASON HIRSCHHORN: Au const - katika sawa.

1013
00:49:02,720 --> 00:49:04,275
Hivyo ni kusema tu
variable kimataifa?

1014
00:49:04,275 --> 00:49:04,990
>> MWANAFUNZI: Yeah.

1015
00:49:04,990 --> 00:49:08,670
>> JASON HIRSCHHORN: Hivyo stylistically,
hakuna lazima haki ya mmoja

1016
00:49:08,670 --> 00:49:12,050
kujibu, lakini wote wawili hao ni bora
kuliko tu kutupa hizi random

1017
00:49:12,050 --> 00:49:12,960
idadi katika kanuni yako.

1018
00:49:12,960 --> 00:49:14,650
Sisi kuwaita uchawi namba.

1019
00:49:14,650 --> 00:49:16,450
Wakati mimi kuangalia code yako au wakati
mtu yeyote ni kusoma kwa njia ya hayo,

1020
00:49:16,450 --> 00:49:18,790
hawataki tu namba hizi random
kwamba si mantiki.

1021
00:49:18,790 --> 00:49:22,420
Hata namba 26, ambayo kwa ujumla ni
idadi ya herufi katika alfabeti,

1022
00:49:22,420 --> 00:49:28,870
ni bora kufafanua ALPHABET juu juu
na kuokoa namba 26 katika kamba kwamba,

1023
00:49:28,870 --> 00:49:29,550
kama kwamba hufanya akili.

1024
00:49:29,550 --> 00:49:33,210
>> Au juu ya tatizo kuweka moja, badala ya -
tena, hatukuwa na majadiliano kuhusu hili katika

1025
00:49:33,210 --> 00:49:37,020
muda, lakini badala ya kutupa tu
25 katika kila mahali au 10, unaweza

1026
00:49:37,020 --> 00:49:41,860
kuokoa namba 25 kama QUARTER au 10 kama
DIME, na kwamba inafanya kuwa rahisi kwa

1027
00:49:41,860 --> 00:49:44,140
yeyote ni kusoma kwa njia ya kanuni yako
kuelewa kwa nini alichagua kwamba idadi.

1028
00:49:44,140 --> 00:49:46,540
Na pia kwa ajili yenu, kama wewe milele unataka
update ya kanuni yako, inafanya kuwa ni kidogo

1029
00:49:46,540 --> 00:49:47,290
imara zaidi.

1030
00:49:47,290 --> 00:49:48,070
Yeah?

1031
00:49:48,070 --> 00:49:50,830
>> MWANAFUNZI: Je kanuni hii pia kwenda
kwa kuwa inapatikana kwa ajili yetu baada ya?

1032
00:49:50,830 --> 00:49:52,453
>> JASON HIRSCHHORN: All wa kanuni hizi
kwamba sisi wameandika pamoja ni

1033
00:49:52,453 --> 00:49:54,620
kwenda kuwa Emailed na wewe
guys na inapatikana.

1034
00:49:54,620 --> 00:49:55,740
Ndiyo.

1035
00:49:55,740 --> 00:49:58,040
Ili kuuliza mtumiaji kwa ajili ya majina matano.

1036
00:49:58,040 --> 00:50:00,280
Nasibu kuchagua na magazeti
moja ya majina.

1037
00:50:00,280 --> 00:50:00,940
Ambaye alifanya mstari huu?

1038
00:50:00,940 --> 00:50:02,230
Hii ni line trickiest hapa.

1039
00:50:02,230 --> 00:50:02,450
Samahani, Tom.

1040
00:50:02,450 --> 00:50:05,510
Wewe alifanya kazi nzuri kwa kweli, lakini
hii ni kidogo trickier.

1041
00:50:05,510 --> 00:50:06,600
Marcus, kwenda mbele.

1042
00:50:06,600 --> 00:50:10,180
>> MWANAFUNZI: Naam kwanza, wewe ni kwenda
haja ya pamoja na stdlib.h time.h.

1043
00:50:10,180 --> 00:50:13,200
>> JASON HIRSCHHORN: Hivyo ni kusema katika
juu, pamoja na mbili maktaba zaidi.

1044
00:50:13,200 --> 00:50:18,830
Unataka mimi ni pamoja na S-T-D-L-I-B
dot H, Standard Library, na nini

1045
00:50:18,830 --> 00:50:19,760
alikuwa mtu mwingine?

1046
00:50:19,760 --> 00:50:21,010
>> MWANAFUNZI: Time.h.

1047
00:50:21,010 --> 00:50:25,130

1048
00:50:25,130 --> 00:50:27,840
>> JASON HIRSCHHORN: # pamoja time.h.

1049
00:50:27,840 --> 00:50:29,470
Basi hizi ni mbili zaidi maktaba.

1050
00:50:29,470 --> 00:50:31,790
Mimi kudhani sasa tunakwenda kuwa na kutumia
kazi ambayo ni zilizomo katika haya

1051
00:50:31,790 --> 00:50:34,240
mbili, ambayo ni kwa nini unahitajika
pamoja nao?

1052
00:50:34,240 --> 00:50:36,980
>> MWANAFUNZI: Hivyo basi, kwanza wewe ni
kwenda kutaka kuandika srand.

1053
00:50:36,980 --> 00:50:38,770
>> JASON HIRSCHHORN: Srand.

Mimi nina kwenda tu kuchukua nafasi ya
sifuri yako na null.

1063
00:50:53,610 --> 00:50:55,980
Hivyo itabidi kufanya kuhusu jambo moja, lakini
ujumla, utaona NULL, ambayo

1064
00:50:55,980 --> 00:50:57,720
tutaweza kuzungumzia hii
mstari katika pili.

00:52:08,480 --> 00:52:11,630
Si. / Mwanafunzi. . / Wanafunzi.

1112
00:52:11,630 --> 00:52:12,870
Jina moja.

1113
00:52:12,870 --> 00:52:15,490
Tutaweza kusema Daudi.

1114
00:52:15,490 --> 00:52:18,070
Jina mbili, RJ.

1115
00:52:18,070 --> 00:52:20,561
Jina tatu, Rob.

1116
00:52:20,561 --> 00:52:22,490
Jina nne, Lucas.

1117
00:52:22,490 --> 00:52:26,060
Jina tano, Yusufu.

1118
00:52:26,060 --> 00:52:28,850
Na kisha Prints nje Joseph tena.

1119
00:52:28,850 --> 00:52:31,730
>> Hivyo basi mimi kukimbia hii tena.

1120
00:52:31,730 --> 00:52:32,460
Basi mimi kufanya majina sawa.

1121
00:52:32,460 --> 00:52:39,760
Daudi, RJ, Rob, Lucas, Yusufu.

1122
00:52:39,760 --> 00:52:41,070
Na alinipa Daudi wakati huu.

1123
00:52:41,070 --> 00:52:43,030
Hivyo sikuwa kitu kimoja, lakini lilitoa
mimi kitu tofauti, na kwamba

1124
00:52:43,030 --> 00:52:45,410
kwa sababu, bila shaka, sisi ni kuuliza
kwa jina random.

1125
00:52:45,410 --> 00:52:50,950
Hivyo nadhani, msingi mbali ya mimi Mabedui
kuzunguka chumba, kwamba watu wengi

1126
00:52:50,950 --> 00:52:55,960
pengine got kwanza sehemu ya haki,
kuanzisha kwamba safu na kisha kupata

1127
00:52:55,960 --> 00:52:56,430
majina yote.

1128
00:52:56,430 --> 00:52:59,320
Mimi kuzungumza juu ya mistari ya 10 kupitia 16.

1129
00:52:59,320 --> 00:53:02,150
Lakini mistari 18 kupitia 21 pengine ni
baadhi ya mambo hawajaona kabla,

1130
00:53:02,150 --> 00:53:03,750
hivyo hebu kwenda kwa njia hizo.

1131
00:53:03,750 --> 00:53:10,390
>> Mstari huu, srand wakati NULL
kimsingi ni -

1132
00:53:10,390 --> 00:53:14,300
sorry, basi turuke
mstari, rand ().

1133
00:53:14,300 --> 00:53:17,320
Kwamba anatoa simu random,
integer random.

1134
00:53:17,320 --> 00:53:19,630
Na kama wewe hit rand mtu, ambayo
mengi ya alivyofanya -

1135
00:53:19,630 --> 00:53:21,530
M-A-N nafasi R-A-N-D -

1136
00:53:21,530 --> 00:53:25,910
katika terminal kama hii, M-A-N
nafasi ya R-A-N-D, hit kuingia.

1137
00:53:25,910 --> 00:53:30,490
Ungependa kuja na mwongozo na
itakuwa na uwezo wa kusoma kwamba rand

1138
00:53:30,490 --> 00:53:34,260
amri matokeo num Pseudo random ka
baada ya mbegu idadi random

1139
00:53:34,260 --> 00:53:35,510
jenereta moja.

1140
00:53:35,510 --> 00:53:38,450

1141
00:53:38,450 --> 00:53:39,700
>> Hivyo kwamba ni maelezo.

1142
00:53:39,700 --> 00:53:43,860

1143
00:53:43,860 --> 00:53:46,800
Hiyo ni nini rand gani, anatoa
wewe idadi random wakati

1144
00:53:46,800 --> 00:53:48,610
wewe piga kwamba kazi.

1145
00:53:48,610 --> 00:53:53,140
Kwa bahati mbaya, si kweli random
kwa sababu kama wewe piga tu random

1146
00:53:53,140 --> 00:53:55,970
bila kupata ni baadhi ya mbegu, baadhi ya
kuanzia, itakuwa daima kuchagua

1147
00:53:55,970 --> 00:53:59,100
moja moja na anatumia formula
kuamua moja ijayo.

1148
00:53:59,100 --> 00:54:01,730
Hivyo kama wewe piga rand, ni itabidi tu
kukupa kitu kimoja.

1149
00:54:01,730 --> 00:54:02,610
Itakuwa sana kutabirika.

1150
00:54:02,610 --> 00:54:03,790
Ni kweli si kuwa random.

1151
00:54:03,790 --> 00:54:09,610
>> Hivyo nini tunahitaji kufanya, per ya Marcus
maelekezo na mimi, walikuwa mbegu ya rand

1152
00:54:09,610 --> 00:54:13,810
na kitu kingine, ambayo ni nini
kazi srand gani.

1153
00:54:13,810 --> 00:54:18,055
Ni mbegu rand na kitu kidogo zaidi
random kuliko kitu kimoja, na

1154
00:54:18,055 --> 00:54:23,360
yeye ni pamoja na mbegu NULL muda, ambayo
ni, tu kwa mkataba, sasa

1155
00:54:23,360 --> 00:54:24,650
wakati katika sekunde.

1156
00:54:24,650 --> 00:54:29,790
>> Hivyo wewe ni kuchukua kwamba kila mtu si
kwenda kukimbia katika kanuni halisi

1157
00:54:29,790 --> 00:54:33,620
pili huo, hivyo ni bet salama kwamba
wakati NULL ni kwenda kuwa tofauti

1158
00:54:33,620 --> 00:54:35,250
kila wakati kanuni hii ni kukimbia.

1159
00:54:35,250 --> 00:54:39,020
Salama bet kuwa hivyo, srand mapenzi mbegu rand
na kitu tofauti kila

1160
00:54:39,020 --> 00:54:39,990
moja wakati.

1161
00:54:39,990 --> 00:54:44,110
Hivyo kwa mkataba, wakati sisi kufanya unataka
idadi random, sisi kuandika mstari huu,

1162
00:54:44,110 --> 00:54:50,540
srand wakati null, kutupatia kiasi
zaidi random mbegu, na kisha sisi kukimbia

1163
00:54:50,540 --> 00:54:52,080
rand, ambayo inatupa simu random.

1164
00:54:52,080 --> 00:54:52,840
Yeah?

1165
00:54:52,840 --> 00:54:54,140
>> MWANAFUNZI: Je, unaweza kusema nini
maana ya mbegu?

1166
00:54:54,140 --> 00:54:55,630
>> JASON HIRSCHHORN: Mbegu kama katika -

1167
00:54:55,630 --> 00:54:58,730
hivyo rand ni kwenda kuchukua baadhi ya idadi
na ni kwenda kutumia baadhi

1168
00:54:58,730 --> 00:55:00,060
formula ya kufika huko.

1169
00:55:00,060 --> 00:55:03,250
Hivyo ni kwenda kuanza na kitu
na kisha kurejea ndani kitu ya msingi

1170
00:55:03,250 --> 00:55:03,890
mbali ya formula kwamba.

1171
00:55:03,890 --> 00:55:06,090
Kama wewe daima kuwapa kitu kimoja,
ni daima kwenda kugeuka ndani

1172
00:55:06,090 --> 00:55:06,790
kitu kimoja.

1173
00:55:06,790 --> 00:55:08,450
Ili kwamba jambo la kwanza
kutoa ni mbegu.

1174
00:55:08,450 --> 00:55:10,880
Hivyo unataka kumpa kitu
tofauti na kuanza nje na, na hivyo

1175
00:55:10,880 --> 00:55:12,610
hajaigeuza kuwa kitu tofauti.

1176
00:55:12,610 --> 00:55:15,840
>> Na kisha hatimaye, line 20,
% hii inaitwa

1177
00:55:15,840 --> 00:55:17,470
modulo, na kwamba ni utata.

1178
00:55:17,470 --> 00:55:19,850
Hiyo ni kitu ambacho ni kidogo
mbalimbali hapa kwamba wewe si kweli

1179
00:55:19,850 --> 00:55:22,240
kuwa katika math halisi ya maisha.

1180
00:55:22,240 --> 00:55:27,430
Lakini kimsingi, wakati wewe kuchukua kubwa
idadi na kugawanya katika C, nini

1181
00:55:27,430 --> 00:55:29,482
kinachotokea kwa salio?

1182
00:55:29,482 --> 00:55:30,510
>> MWANAFUNZI: Ni anapata truncated.

1183
00:55:30,510 --> 00:55:31,220
>> HIRSCHHORN JASON: Ni anapata truncated.

1184
00:55:31,220 --> 00:55:35,200
Hivyo 20 kugawanywa na 3 ni nini?

1185
00:55:35,200 --> 00:55:37,950
Je, hiyo kurudi
wewe, 20 kugawanywa na 3.

1186
00:55:37,950 --> 00:55:39,260
Samahani, 10 kugawanywa na 3.

1187
00:55:39,260 --> 00:55:41,062
Je, hiyo kurudi kwenu?

1188
00:55:41,062 --> 00:55:41,540
>> MWANAFUNZI: [inaudible].

1189
00:55:41,540 --> 00:55:45,170
>> JASON HIRSCHHORN: 10 kugawanywa na 3 tu
anarudi 3, si 3 salio 1.

1190
00:55:45,170 --> 00:55:51,490
Hivyo kile 10 modulo 3 anarudi
ni tu salio, 1.

1191
00:55:51,490 --> 00:55:54,020
Hivyo kama alitaka kujua nini 10 kugawanywa
na 3 kweli alikuwa, ungekuwa

1192
00:55:54,020 --> 00:55:58,950
kufanya 10 kugawanywa na 3, utaweza kupata 3 yako,
na kisha wewe d kufanya 10 modulo 3, na

1193
00:55:58,950 --> 00:55:59,860
Ningependa kupata 1.

1194
00:55:59,860 --> 00:56:04,630
Hivyo d kutambua kwamba 10 kugawanywa
na 3 ni 3, salio 1.

1195
00:56:04,630 --> 00:56:07,990
>> Na katika mstari huu, rand inaweza kuwa
yoyote integer, kimsingi.

1196
00:56:07,990 --> 00:56:12,660
Hivyo modulo ni kusema, kuigawanya na
simu, ambayo ni katika kesi hii 5.

1197
00:56:12,660 --> 00:56:16,420
Na kama wewe milele kugawanya na posta,
integer daima ina kuwa chini ya

1198
00:56:16,420 --> 00:56:17,590
idadi hiyo.

1199
00:56:17,590 --> 00:56:22,200
Hivyo kama wewe ni kugawa na idadi 5,
salio ni daima itakuwa

1200
00:56:22,200 --> 00:56:23,396
sifuri kwa njia ya nne.

1201
00:56:23,396 --> 00:56:25,520
Hiyo tu jinsi math kazi nje.

1202
00:56:25,520 --> 00:56:29,700
>> Hivyo idadi kubwa moduloed na ndogo
idadi daima kurudi

1203
00:56:29,700 --> 00:56:33,530
salio na daima kurudi baadhi
idadi hiyo ni chini ya idadi wewe

1204
00:56:33,530 --> 00:56:34,693
kugawanywa na.

1205
00:56:34,693 --> 00:56:37,920
Je, mtu yeyote una maswali yoyote kuhusu
modulo, kwa sababu atakuja katika sana,

1206
00:56:37,920 --> 00:56:41,450
Handy sana, hivyo mimi nataka kuhakikisha
kila mtu anaelewa hivyo?

1207
00:56:41,450 --> 00:56:43,710
Baridi.

1208
00:56:43,710 --> 00:56:46,000
Na tuliona kwamba mpango huu kazi.

1209
00:56:46,000 --> 00:56:50,280
OK, kuhama.

1210
00:56:50,280 --> 00:56:52,970
>> Hivyo ijayo, tunakwenda kwenda katika
kazi, na tunakwenda kwenda

1211
00:56:52,970 --> 00:56:55,580
njia ya mapumziko ya mambo haya pretty
haraka kwa sababu nataka kupata

1212
00:56:55,580 --> 00:56:57,150
amri line mabishano.

1213
00:56:57,150 --> 00:57:00,330
Hivyo kazi ni kimsingi,
kama wameweza kuona, nyeusi masanduku.

1214
00:57:00,330 --> 00:57:04,290
Wao kuchukua mambo katika vigezo kuitwa,
wao kufanya kitu kwao, ama

1215
00:57:04,290 --> 00:57:06,990
mabadiliko yao au kuunda baadhi ya madhara,
na hatimaye, wakamtemea mate

1216
00:57:06,990 --> 00:57:09,530
kitu nje, ambayo ni
thamani ya kurudi.

1217
00:57:09,530 --> 00:57:12,495
Mtu yeyote anaweza kunipa sababu moja
nini tunataka kutumia kazi?

1218
00:57:12,495 --> 00:57:15,870

1219
00:57:15,870 --> 00:57:16,360
Mtu yeyote?

1220
00:57:16,360 --> 00:57:19,360
Sababu moja kwa nini tunatarajia kutumia kazi?

1221
00:57:19,360 --> 00:57:21,280
Mtu yeyote?

1222
00:57:21,280 --> 00:57:22,700
Nikaona mikono miwili.

1223
00:57:22,700 --> 00:57:23,590
Nini sababu nzuri?

1224
00:57:23,590 --> 00:57:24,930
Marcus?

1225
00:57:24,930 --> 00:57:27,730
>> MWANAFUNZI: Kama una kuwaita huo
chunk ya kanuni mara nyingi.

1226
00:57:27,730 --> 00:57:29,150
>> JASON HIRSCHHORN: Sawa, kama unahitaji
kuwaita chunk hiyo ya

1227
00:57:29,150 --> 00:57:30,040
kanuni mara nyingi.

1228
00:57:30,040 --> 00:57:32,470
Jeff, je una sababu tofauti?

1229
00:57:32,470 --> 00:57:34,230
>> MWANAFUNZI: Tu ili
unaweza kanuni chini.

1230
00:57:34,230 --> 00:57:35,070
>> JASON HIRSCHHORN: Unaweza kanuni chini.

1231
00:57:35,070 --> 00:57:35,320
Haki.

1232
00:57:35,320 --> 00:57:38,720
Kama unataka kufanya kitu mengi -

1233
00:57:38,720 --> 00:57:41,720
katika kanuni uliopita, mimi nilikuwa na
imeandikwa kupata kamba mara tano, lakini

1234
00:57:41,720 --> 00:57:44,620
kwa kitanzi inafanya kuangalia nicer na
una kuandika chini ya kanuni.

1235
00:57:44,620 --> 00:57:45,760
Kazi ni wazo sawa.

1236
00:57:45,760 --> 00:57:48,720
Kama mimi nataka kufanya kitu kimoja mengi,
hoja hiyo kwa kazi na wito kwamba

1237
00:57:48,720 --> 00:57:49,610
kazi kila wakati.

1238
00:57:49,610 --> 00:57:51,190
Kwamba kufanya jambo kwa ajili yenu.

1239
00:57:51,190 --> 00:57:53,740
Hiyo ni sababu kubwa
kutumia kazi.

1240
00:57:53,740 --> 00:57:54,870
>> Hivyo anatomy ya kazi.

1241
00:57:54,870 --> 00:57:56,670
kazi mapenzi kwa ujumla
kuangalia kama hii.

1242
00:57:56,670 --> 00:57:59,280
Hivyo itabidi kuanza na aina ya kurudi,
kisha utapata jina.

1243
00:57:59,280 --> 00:58:02,935
Ni itabidi kuchukua hoja, vinginevyo
inayojulikana kama vigezo, na ndani ya

1244
00:58:02,935 --> 00:58:05,290
wale braces curly, itabidi
kuandika code yako.

1245

>> Tumeona moja ya kazi mengi.

1246
00:58:07,150 --> 00:58:09,160
Hiyo ni kuu.

1247
00:58:09,160 --> 00:58:13,820
Hapa ni kuu superimposed kwenye
kwamba anatomy nilishawahi.

1248
00:58:13,820 --> 00:58:15,525
Je int haki hapa yanamaanisha?

1249
00:58:15,525 --> 00:58:18,534

1250
00:58:18,534 --> 00:58:19,450
Je int maana?

1251
00:58:19,450 --> 00:58:21,026
Wakati mimi kuandika int kuu (batili).

1252
00:58:21,026 --> 00:58:21,740

1257
00:58:25,870 --> 00:58:28,678
Je, ni kuu?

1258
00:58:28,678 --> 00:58:29,510
>> MWANAFUNZI: Kazi jina.

00:58:31,510 --> 00:58:31,840
Na batili?

1262
00:58:31,840 --> 00:58:33,190
Je, ni utupu ndani ya mabano?

1263
00:58:33,190 --> 00:58:36,650

1264

1266
00:58:42,930 --> 00:58:43,240
haki.

1267
00:58:43,240 --> 00:58:45,940
Ndani ya mabano, sisi kuweka
vigezo au hoja

1268
00:58:45,940 --> 00:58:48,480
kazi inachukua, yale yanayoendelea
ndani ya boksi nyeusi.

1269
00:58:48,480 --> 00:58:50,760
Wakati kuandika batili, wewe ni kusema
hii inachukua kitu in

1270
00:58:50,760 --> 00:58:53,802
Hivyo int utupu kuu ina maana kuu ya
si kuchukua kitu in

1271
00:58:53,802 --> 00:58:56,950
>> Ndani ya braces curly, tuna baadhi ya
kanuni, na kisha tunaona mwishoni

1272
00:58:56,950 --> 00:58:57,640
kurudi sifuri.

1273
00:58:57,640 --> 00:59:01,220
Je kurudi sifuri maana?

1274
00:59:01,220 --> 00:59:02,470
Naam, sisi aliyesema kuhusu aina ya kurudi.

1275
00:59:02,470 --> 00:59:03,780
Kuu ya mahitaji ya kurudi int.

1276
00:59:03,780 --> 00:59:04,960
Hiyo ni nini mstari huu gani.

1277
00:59:04,960 --> 00:59:07,330
Kuirudisha int, sifuri.

1278
00:59:07,330 --> 00:59:13,600
>> Bila shaka, hatujaona kwamba mengi
kwa sababu katika programu sisi kufanya na

1279
00:59:13,600 --> 00:59:16,070
mashine sisi kufanya na watunzi
sisi kutumia siku hizi, wewe

1280
00:59:16,070 --> 00:59:16,990
hawana haja ya kuwa mstari.

1281
00:59:16,990 --> 00:59:20,070
Kuu ni maalum kutosha kwamba anajua
wakati wewe kufikia mwisho wa kuu, tu

1282
00:59:20,070 --> 00:59:22,060
kurudi sifuri kama kila kitu akaenda vizuri.

1283
00:59:22,060 --> 00:59:25,560
Kwa kweli, kama kitu haina kwenda vizuri,
kuu mara nyingi kurudi tofauti

1284
00:59:25,560 --> 00:59:28,500
idadi akionyesha kwamba kitu
potoka na programu yako.

1285
00:59:28,500 --> 00:59:32,470
>> Hivyo kwa ujumla wakati unaweza kuona kanuni, wewe
wala kuandika kurudi sifuri, lakini ni vizuri

1286
00:59:32,470 --> 00:59:34,770
kujua kwamba kinatokea nyuma ya
pazia kwa sababu wakati wewe kuandika

1287
00:59:34,770 --> 00:59:36,370
aina nyingine ya kazi,
wewe ni kwenda haja ya

1288
00:59:36,370 --> 00:59:37,400
ni pamoja na mstari kurudi.

1289
00:59:37,400 --> 00:59:39,710
Kama wewe ni kusema mimi nina kwenda
kurudi int, una

1290
00:59:39,710 --> 00:59:41,250
kuandika kurudi kitu.

1291
00:59:41,250 --> 00:59:45,160
Kama kusema utupu hadi hapa katika
mwanzo, utupu kuu batili, kwa

1292
00:59:45,160 --> 00:59:48,670
mfano, basi ni si kurudi
kitu chochote - utupu maana kitu -

1293
00:59:48,670 --> 00:59:50,320
hivyo huna haja ya kuwa mstari wa kurudi.

1294
00:59:50,320 --> 00:59:53,610
Lakini wewe milele kuandika kitu ambacho si
utupu kwa aina ya kurudi, unahitaji

1295
00:59:53,610 --> 00:59:55,950
Mpya kwamba anasema kurudi na wewe
haja ya kuweka kitu pale

1296
00:59:55,950 --> 00:59:57,650
kwamba mechi aina.

1297
00:59:57,650 --> 00:59:58,900
Maswali yoyote kuhusu hilo?

1298
00:59:58,900 --> 01:00:03,110

1299
01:00:03,110 --> 01:00:04,680
Tamu.

1300
01:00:04,680 --> 01:00:05,930
>> Upeo.

1301
01:00:05,930 --> 01:00:07,360
Hii ni kitu tumekuwa
kuguswa juu pia.

1302
01:00:07,360 --> 01:00:10,720
Kutofautiana kila, kama tujuavyo, ina
baadhi ya upeo, na kwamba kimsingi

1303
01:00:10,720 --> 01:00:14,160
kuzungumza juu ambapo kutofautiana
au anaweza kuwa referenced.

1304
01:00:14,160 --> 01:00:16,310
Na mimi kama kusema nini kinatokea
katika braces curly anakaa

1305
01:00:16,310 --> 01:00:18,000
ndani ya braces curly.

1306
01:00:18,000 --> 01:00:21,490
Hivyo kwa mfano, kama sisi kuangalia kanuni hii,
sisi ni kufafanua variable kimataifa

1307
01:00:21,490 --> 01:00:24,510
nje ya kuu, int a,
hapa juu kwa juu.

1308
01:00:24,510 --> 01:00:27,380
Sisi ni wito mwingine
int ndani kuu.

1309
01:00:27,380 --> 01:00:29,760
Tuna braces baadhi ya zaidi curly, na
sisi ni wito mwingine a int.

1310
01:00:29,760 --> 01:00:31,690
>> Tuna tatu katika kanuni.

1311
01:00:31,690 --> 01:00:32,550
Haya si kitu kimoja.

1312
01:00:32,550 --> 01:00:34,880
Nimekuwa umba tatu vigezo tofauti.

1313
01:00:34,880 --> 01:00:39,370
Basi ndani ya hizi curly ndani
braces, nasema 4 =.

1314
01:00:39,370 --> 01:00:44,130
Ambayo ni kwamba kuzungumza juu,
kwanza moja, moja ya pili,

1315
01:00:44,130 --> 01:00:47,045
au moja ya tatu?

1316
01:00:47,045 --> 01:00:47,920
>> MWANAFUNZI: moja ya tatu.

1317
01:00:47,920 --> 01:00:49,320
>> JASON HIRSCHHORN: Ni kuzungumza
juu ya theluthi moja.

1318
01:00:49,320 --> 01:00:52,850
Wote wa wale kweli unaweza kuwa
kuongelea katika hili hasa

1319
01:00:52,850 --> 01:00:58,660
mfano kwa sababu upeo wao wote huenda
katika haya yaliyomo braces curly.

1320
01:00:58,660 --> 01:01:02,360
Hata hivyo, wakati wewe piga mambo sawa
jina, kuna kitu kinachoitwa mafichoni.

1321
01:01:02,360 --> 01:01:09,670
Hivyo tu kuhusika na au kurekebisha au kutumia
karibuni zaidi kutofautiana, au mmoja

1322
01:01:09,670 --> 01:01:11,090
karibu na wewe.

1323
01:01:11,090 --> 01:01:14,760
Hivyo ndani ya hapa, a hii ya tatu ni karibu
na mstari huo, = 4, hivyo

1324
01:01:14,760 --> 01:01:16,550
huathiri moja ya tatu.

1325
01:01:16,550 --> 01:01:19,890
Na mstari wa mwisho, = 2, ambayo ni
kwamba kuzungumza juu, kwanza, pili,

1326
01:01:19,890 --> 01:01:20,805
au tatu?

1327
01:01:20,805 --> 01:01:22,530
>> MWANAFUNZI: Pili.

1328
01:01:22,530 --> 01:01:24,430
>> JASON HIRSCHHORN: Ni kuzungumza
kuhusu a pili.

1329
01:01:24,430 --> 01:01:27,970
Bila shaka, ya tatu ni karibu na
katika kanuni, lakini wa tatu

1330
01:01:27,970 --> 01:01:30,200
haipo nje
wale braces curly.

1331
01:01:30,200 --> 01:01:32,650
Mara baada ya kupata na kwamba curly kufungwa
brace, ni kama ni gone,

1332
01:01:32,650 --> 01:01:33,570
kimsingi.

1333
01:01:33,570 --> 01:01:36,150
Hivyo wawili tu una kushoto ni wale
mbili za kwanza, na bila shaka, sasa

1334
01:01:36,150 --> 01:01:37,960
ni karibu na moja ya pili.

1335
01:01:37,960 --> 01:01:39,410
>> Hivyo kwamba ni jambo zuri
kukumbuka juu ya upeo.

1336
01:01:39,410 --> 01:01:42,900
Kwa mfano, mimi nina uhakika umefanya wamekutana
hii katika kufanya wakati kitanzi.

1337
01:01:42,900 --> 01:01:46,680
Kama wewe initialize ndani ya kutofautiana
wala wakati kitanzi na kisha wewe kujaribu

1338
01:01:46,680 --> 01:01:50,360
kupata huduma hiyo nje, pengine
got baadhi ya onyo kama, hii

1339
01:01:50,360 --> 01:01:51,680
kutofautiana haipo.

1340
01:01:51,680 --> 01:01:54,370
Hiyo ni kwa sababu ya wazo upeo,
kwamba mambo tu kuwepo

1341
01:01:54,370 --> 01:01:55,320
ndani ya wale braces curly.

1342
01:01:55,320 --> 01:01:59,320
Curly braces ni kama kumkumbatia kubwa kwamba
wewe ni kutoa na kanuni yako, ni mwingine

1343
01:01:59,320 --> 01:02:01,380
njia ya kufikiri juu yake.

1344
01:02:01,380 --> 01:02:05,280
>> Hivyo hii ni kazi nyingine, kitu
kwa nyie na kanuni, hellofunction.c.

1345
01:02:05,280 --> 01:02:08,240
Tunakwenda ruka kwamba kwa sasa, lakini
hii ni kitu Mimi moyo

1346
01:02:08,240 --> 01:02:09,740
mazoezi ya juu yako mwenyewe.

1347
01:02:09,740 --> 01:02:12,510
Kuandika mpango katika ambayo kuu wito
kazi nyingine kwamba Prints nje

1348
01:02:12,510 --> 01:02:13,750
salamu kwa mtumiaji.

1349
01:02:13,750 --> 01:02:17,750
Ni kimsingi kuchukua dunia hujambo
na abstracting kwamba printf katika

1350
01:02:17,750 --> 01:02:18,680
kazi nyingine.

1351
01:02:18,680 --> 01:02:22,360
Lakini sisi siyo kwenda kufanya kwamba hivi sasa
kwa sababu hatuna kama muda mwingi

1352
01:02:22,360 --> 01:02:23,350
kushoto kama napenda kuwa walipenda.

1353
01:02:23,350 --> 01:02:26,250
>> Hivyo kazi ya tamko.

1354
01:02:26,250 --> 01:02:28,080
Tumeona hii kabla vilevile.

1355
01:02:28,080 --> 01:02:31,180
Kama unataka kuandika kazi nyingine,
unahitaji basi kompyuta kujua na

1356
01:02:31,180 --> 01:02:32,600
kuu kujua kwamba ipo.

1357
01:02:32,600 --> 01:02:37,140
Basi nini hatuwezi ni juu kuu, sisi kuandika
aina ya kurudi, jina, na

1358
01:02:37,140 --> 01:02:42,970
vigezo, na kisha chini chini kuu,
hapa chini, sisi kweli nakala kuwa mstari

1359
01:02:42,970 --> 01:02:45,080
na kisha kuandika kanuni halisi.

1360
01:02:45,080 --> 01:02:50,990
Hivyo njia hii, kama wewe piga kazi
katika kuu saa ya juu, kuu anajua kwamba

1361
01:02:50,990 --> 01:02:54,650
hujambo ipo, kwa mfano, kama ningekuwa
kuwaita hello, na kisha inaonekana kwa

1362
01:02:54,650 --> 01:02:56,710
utekelezaji chini chini.

1363
01:02:56,710 --> 01:02:59,680
Kile kinachotokea kama mimi si pamoja na hii
line up ya juu, utupu hujambo (batili)?

1364
01:02:59,680 --> 01:03:03,820

1365
01:03:03,820 --> 01:03:06,560
>> Kama mimi si ni pamoja na line hii
na wito kuu hello, mimi nina

1366
01:03:06,560 --> 01:03:07,640
kwenda kupata hitilafu.

1367
01:03:07,640 --> 01:03:10,090
Mimi naenda kupata kosa kwa sababu
mkusanyaji hajui

1368
01:03:10,090 --> 01:03:13,070
kwamba jambo hili lipo.

1369
01:03:13,070 --> 01:03:16,680
Hii ni sawa na kwa nini sisi
wala # pamoja cs50.h.

1370
01:03:16,680 --> 01:03:21,390
Nini kimsingi cs50.h ni kufanya
ni kuweka kupata kamba hadi hapo.

1371
01:03:21,390 --> 01:03:23,120
Ni kuweka kupata int hadi huko.

1372
01:03:23,120 --> 01:03:26,570
Ni kuweka wote wa kazi hizo
prototypes juu kabla kuu ili wakati

1373
01:03:26,570 --> 01:03:29,900
wewe kuwaita katika kuu, kuu anajua
kuwa mambo haya zipo.

1374
01:03:29,900 --> 01:03:31,630
Hiyo ni nini wale h. Files kufanya.

1375
01:03:31,630 --> 01:03:33,850
Na hivyo kama wewe ni kwenda kufanya yako mwenyewe
kazi, nimepata kuhakikisha

1376
01:03:33,850 --> 01:03:36,690
kuweka kwamba mfano hadi huko.

1377
01:03:36,690 --> 01:03:38,380
Maswali yoyote kuhusu hii hadi sasa?

1378
01:03:38,380 --> 01:03:41,630

1379
01:03:41,630 --> 01:03:42,490
>> Amri line mabishano.

1380
01:03:42,490 --> 01:03:44,780
Hii ni nini tunakwenda kumaliza
juu, na kisha hopefully tutaweza

1381
01:03:44,780 --> 01:03:46,180
itapunguza katika pset baadhi.

1382
01:03:46,180 --> 01:03:48,700
Mimi sijui kama tutaweza kuwa na uwezo wa itapunguza
kwamba kwa sababu ya muda, lakini

1383
01:03:48,700 --> 01:03:51,560
na wewe guys ambao ni hapa, na kama wewe
guys wanataka kusema baada kwa kidogo, sisi

1384
01:03:51,560 --> 01:03:54,290
wanaweza kwenda juu yake nje.

1385
01:03:54,290 --> 01:03:56,020
Lakini sisi ni kwenda kumaliza na
amri line hoja

1386
01:03:56,020 --> 01:03:58,510
kwa ajili ya mwisho dakika 15.

1387
01:03:58,510 --> 01:03:59,930
Sisi ari, Michael?

1388
01:03:59,930 --> 01:04:01,180
Wewe macho?

1389
01:04:01,180 --> 01:04:01,660
Nzuri.

1390
01:04:01,660 --> 01:04:03,760
Sijui kama wewe kulala
kwa macho yako imefungwa.

1391
01:04:03,760 --> 01:04:05,800
Itakuwa ni gumu.

1392
01:04:05,800 --> 01:04:07,180
>> Amri line mabishano.

1393
01:04:07,180 --> 01:04:10,430
Wale ni moja ya njia ya kupita habari
katika mpango.

1394
01:04:10,430 --> 01:04:12,780
Hatimaye, tutaweza kukutana wengine.

1395
01:04:12,780 --> 01:04:15,600
Lakini kimsingi, tunakwenda na kuacha
kuandika int kuu (utupu) kama tunataka

1396
01:04:15,600 --> 01:04:16,720
kuchukua baadhi ya hoja mstari amri.

1397
01:04:16,720 --> 01:04:19,850
Sisi ni kwenda kuandika jambo hili
kuitwa int kuu (int argc,

1398
01:04:19,850 --> 01:04:22,430
kamba argv, mabano.

1399
01:04:22,430 --> 01:04:23,710
Kwamba ni utata.

1400
01:04:23,710 --> 01:04:26,070
Hiyo mengi ya barua ambayo si katika
binadamu Kiingereza, hivyo tunakwenda

1401
01:04:26,070 --> 01:04:27,680
kinafafanua haki yao sasa.

1402
01:04:27,680 --> 01:04:30,450
>> Argc anasimama kwa kuhesabu hoja -

1403
01:04:30,450 --> 01:04:32,600
na tena, yote haya mapenzi
kuwa inapatikana online -

1404
01:04:32,600 --> 01:04:34,280
na kwamba idadi ya hoja.

1405
01:04:34,280 --> 01:04:37,940
Argv anasimama kwa vector hoja, na
wale ni hoja wenyewe.

1406
01:04:37,940 --> 01:04:38,830
Ni safu ya masharti.

1407
01:04:38,830 --> 01:04:40,880
Tumekuwa kweli kuonekana safu
ya masharti kabla ya leo.

1408
01:04:40,880 --> 01:04:44,390
Sisi aliumba moja katika mwisho
mpango sisi coded.

1409
01:04:44,390 --> 01:04:45,720
>> Hivyo hapa ni mfano.

1410
01:04:45,720 --> 01:04:50,230
Mimi kuandika. / Ohai cs50 sehemu
juu ya mstari amri yangu.

1411
01:04:50,230 --> 01:04:54,090
Argc katika kesi hii ni sawa 3.

1412
01:04:54,090 --> 01:05:01,170
Argv mabano 0 ni ohai, argv mabano 1
ni cs50, argv mabano 2 ni sehemu.

1413
01:05:01,170 --> 01:05:05,160
Tena, argc ni idadi ya hoja,
na safari wewe juu kidogo

1414
01:05:05,160 --> 01:05:08,710
kidogo, sisi daima kuhesabu jina la
kazi kama hoja ya kwanza.

1415
01:05:08,710 --> 01:05:12,350
Hivyo katika kesi hii, kuna mambo matatu
hoja, jina la kazi

1416
01:05:12,350 --> 01:05:14,590
na kisha wale mbili kwamba mimi typed in

1417
01:05:14,590 --> 01:05:18,900
>> Ijayo, sisi ni kwenda kuwaokoa wale
hoja wenyewe katika argv.

1418
01:05:18,900 --> 01:05:22,690
Na tena, kama tuliona kabla, sisi alifanya
hii katika programu ya mwisho sisi coded.

1419
01:05:22,690 --> 01:05:27,110
Unaweza hoja kupitia safu ya
argv na kupata masharti hayo.

1420
01:05:27,110 --> 01:05:28,830
Hiyo ni kimsingi sisi alivyofanya katika
mwisho wa programu yetu ya mwisho.

1421
01:05:28,830 --> 01:05:33,190
Sisi ilichukua jina random na kisha akaenda
majina mabano chochote na kuchapishwa

1422
01:05:33,190 --> 01:05:34,580
nje kamba iko huko.

1423
01:05:34,580 --> 01:05:39,870

1424
01:05:39,870 --> 01:05:43,670
>> Juu ya safu moja tu, kwa sababu
masharti wenyewe ni arrays, kama

1425
01:05:43,670 --> 01:05:46,320
kuongelea, unaweza kuwa na arrays
ya arrays, ambayo ni

1426
01:05:46,320 --> 01:05:48,530
kimsingi ni nini argv ni.

1427
01:05:48,530 --> 01:05:51,370
Njia moja unaweza kufikiri juu ya
hii ni safu na nguzo.

1428
01:05:51,370 --> 01:05:54,750
Siwezi kuteka kwamba hivi sasa.

1429
01:05:54,750 --> 01:05:57,370
Hivyo argv -

1430
01:05:57,370 --> 01:05:58,630
si kwamba kufutwa.

1431
01:05:58,630 --> 01:05:59,880
Hebu kuteka chini ya ohai.

1432
01:05:59,880 --> 01:06:09,320

1433
01:06:09,320 --> 01:06:12,490
>> Hivyo kama mimi aliandika katika, ohai sehemu cs50,
Mimi nina kwenda butu

1434
01:06:12,490 --> 01:06:14,520
sehemu kwa ajili ya mfano huu.

1435
01:06:14,520 --> 01:06:29,026
Lakini kimsingi, yangu multi-dimensional
safu, ohai cs50,

1436
01:06:29,026 --> 01:06:32,200
tunakwenda kufanya dhehebu.

1437
01:06:32,200 --> 01:06:34,610
Hivyo hapa, mimi wanaweza kupata -

1438
01:06:34,610 --> 01:06:40,930

1439
01:06:40,930 --> 01:06:45,710
kama mimi tu kutoa argv namba moja -

1440
01:06:45,710 --> 01:06:46,390
hii ni sahihi.

1441
01:06:46,390 --> 01:06:49,020
Nini kibaya katika mchoro huu?

1442
01:06:49,020 --> 01:06:49,690
>> MWANAFUNZI: Anza katika sifuri.

1443
01:06:49,690 --> 01:06:50,350
>> JASON HIRSCHHORN: Ni lazima
kuanza na sifuri.

1444
01:06:50,350 --> 01:06:52,940
Mimi lazima pengine pia mzunguko yake, lakini
tangu nimekuwa tayari inayotolewa juu, mimi nina

1445
01:06:52,940 --> 01:06:54,120
ataondoka juu huko kwa sasa.

1446
01:06:54,120 --> 01:06:55,160
Lakini kuanza saa sifuri.

1447
01:06:55,160 --> 01:06:56,410
Hiyo ni haki.

1448
01:06:56,410 --> 01:06:58,980

1449
01:06:58,980 --> 01:07:00,120
Samahani kama hii ni ndogo.

1450
01:07:00,120 --> 01:07:01,370
Unaweza guys aina ya kuona?

1451
01:07:01,370 --> 01:07:03,620

1452
01:07:03,620 --> 01:07:06,670
Hivyo kama mimi kufanya argv 0, mimi itabidi
kupata yote ya ohai.

1453
01:07:06,670 --> 01:07:08,555
Kama mimi kufanya argv 1, mimi itabidi kupata yote ya cs50.

1454
01:07:08,555 --> 01:07:10,720
Kama mimi kufanya argv 2, mimi itabidi kupata yote ya dhehebu.

1455
01:07:10,720 --> 01:07:13,370
>> Lakini sasa, kama tulivyosema, masharti
ni arrays wenyewe.

1456
01:07:13,370 --> 01:07:19,740
Hivyo nini siwezi kufanya ni naweza kutibu hii
kama safu multi-dimensional, na mimi

1457
01:07:19,740 --> 01:07:24,190
wanaweza kufanya kitu pamoja na mistari ya
argv 0, 0, ambayo inatoa mimi tu

1458
01:07:24,190 --> 01:07:25,400
tabia 0.

1459
01:07:25,400 --> 01:07:28,760
Argv 0, 1, ambayo inatoa mimi tu h.

1460
01:07:28,760 --> 01:07:33,960
Argv 1, 3, ambayo inatoa mimi tu
hii 0 chini hapa katika cs50.

1461
01:07:33,960 --> 01:07:37,690
>> Hivyo kwa sababu masharti wenyewe
ni arrays, sisi ni kuweka

1462
01:07:37,690 --> 01:07:38,540
kwamba katika safu nyingine.

1463
01:07:38,540 --> 01:07:42,850
Sisi sasa kuwa na safu ya arrays, na sisi
unaweza index katika safu yetu ya kwanza na

1464
01:07:42,850 --> 01:07:44,840
kisha index katika safu yetu ya pili.

1465
01:07:44,840 --> 01:07:48,650
Na kama ungependa kutarajia, sisi kufanya hivyo
na kuweka tu hizo mbili -

1466
01:07:48,650 --> 01:07:51,760
sisi kufanya mabano mraba tu
haki ya karibu na mtu mwingine.

1467
01:07:51,760 --> 01:07:58,930
Hivyo katika mfano huu, argv 1 ni cs50 na
argv 1, 2, kama sisi alisema, ni 5 tu.

1468
01:07:58,930 --> 01:08:02,120
Je, mtu yeyote una maswali yoyote kuhusu
multi-dimensional arrays?

1469
01:08:02,120 --> 01:08:05,090

1470
01:08:05,090 --> 01:08:06,380
Nyie ni kufanya kutisha.

1471
01:08:06,380 --> 01:08:07,750
Tamu.

1472
01:08:07,750 --> 01:08:11,980
>> Hivyo tuna mpango mwingine hapa hapa,
na hili ni jambo la mwisho tuko

1473
01:08:11,980 --> 01:08:13,690
kwenda kufanya hivi sasa.

1474
01:08:13,690 --> 01:08:18,160
Hivyo mimi nataka wewe uandike mpango kwamba
inachukua mtumiaji jina kamili, wawili tu

1475
01:08:18,160 --> 01:08:21,649
mbili amri line hoja, na hatimaye,
magazeti nje salamu kwa

1476
01:08:21,649 --> 01:08:24,180
user kuwa ni pamoja na majina yao ya kwanza.

1477
01:08:24,180 --> 01:08:27,800
Hivyo kwa nini wewe si kuchukua tatu au nne
dakika ya kufanya hili, na kisha tutaweza kwenda

1478
01:08:27,800 --> 01:08:29,870
juu yake kama kikundi, na
basi tutaweza wrap up?

1479
01:08:29,870 --> 01:09:44,189

1480
01:09:44,189 --> 01:09:48,084
>> Na tena, hapa, wakati sisi kusema kuchukua
mtumiaji jina kamili kwa maelezo

1481
01:09:48,084 --> 01:09:54,473
wa tatizo hili, ni lazima kuwa amri
line hoja, si kutumia kupata kamba.

1482
01:09:54,473 --> 01:09:55,450
Yeah, Marcus?

1483
01:09:55,450 --> 01:09:58,260
>> MWANAFUNZI: Hivyo unaposema mbili amri
line hoja, ni kwamba kwa kuongeza

1484
01:09:58,260 --> 01:10:00,000
. / Kukimbia, au -

1485
01:10:00,000 --> 01:10:02,980
>> JASON HIRSCHHORN: Good swali.

1486
01:10:02,980 --> 01:10:05,995
Je, ikiwa ni pamoja /. Kukimbia, tatu
amri line mabishano.

1487
01:10:05,995 --> 01:10:08,550

1488
01:10:08,550 --> 01:10:11,320
Au ikiwa ni pamoja /. Msako, katika
kesi hii, kwa sababu hiyo ni

1489
01:10:11,320 --> 01:10:12,360
jina la faili hii.

1490
01:10:12,360 --> 01:10:13,300
Hivyo argc itakuwa tatu.

1491
01:10:13,300 --> 01:10:19,480
Lakini nataka hoja mbili tu
kutolewa kwa mpango.

1492
01:10:19,480 --> 01:10:20,400
Mimi lazima bayana kwamba.

1493
01:10:20,400 --> 01:10:23,380
Mimi itabidi kufanya mabadiliko kabla mimi baada ya
haya na kuwatuma nyie.

1494
01:10:23,380 --> 01:10:32,747

1495
01:10:32,747 --> 01:10:34,740
>> MWANAFUNZI: Je, kama wewe
kuwa na jina kati?

1496
01:10:34,740 --> 01:10:36,800
>> JASON HIRSCHHORN: Kama una katikati
jina, uko nje ya bahati.

1497
01:10:36,800 --> 01:10:38,050
Samahani.

1498
01:10:38,050 --> 01:10:40,320

1499
01:10:40,320 --> 01:10:43,744
Au kama wewe tu kwenda na Shakira,
wewe ni pia nje ya bahati.

1500
01:10:43,744 --> 01:10:55,672

1501
01:10:55,672 --> 01:10:56,425
Yeah?

1502
01:10:56,425 --> 01:11:00,760
>> MWANAFUNZI: Hivyo wakati watu hawana
cs50.h, je, wao kufafanua argv

1503
01:11:00,760 --> 01:11:03,450
kama Char nyota argv?

1504
01:11:03,450 --> 01:11:05,160
Au ni bado alimwita kamba argv?

1505
01:11:05,160 --> 01:11:07,430
>> JASON HIRSCHHORN: Ndiyo.

1506
01:11:07,430 --> 01:11:10,480
Hivyo kamba, tena, sisi kufunika juu ya kile
hasa kinachotokea huko.

1507
01:11:10,480 --> 01:11:14,040
Hiyo kwenda unpacked labda
Jumatano, lakini hivi karibuni.

1508
01:11:14,040 --> 01:11:16,380
Ni kama magurudumu mafunzo.

1509
01:11:16,380 --> 01:11:18,370
Kwa sababu kimsingi, ni
kitu kimoja.

1510
01:11:18,370 --> 01:11:37,040

1511
01:11:37,040 --> 01:11:42,560
>> Basi hebu kuchukua mwingine dakika ya mpango
hii, na kisha sisi kwenda juu ya

1512
01:11:42,560 --> 01:11:45,130
ni kama kundi, na kisha
kama nilivyosema, wrap up.

1513
01:11:45,130 --> 01:11:47,770
Na nadhani wao ni bado ziada pipi,
hivyo nyie lazima hopefully kuchukua

1514
01:11:47,770 --> 01:11:49,790
kwamba, au tafadhali kuchukua hiyo.

1515
01:11:49,790 --> 01:12:20,380

1516
01:12:20,380 --> 01:12:22,560
>> Pole kama wewe bado kuandika,
lakini nataka kupiga mbizi katika na sisi

1517
01:12:22,560 --> 01:12:24,010
unaweza kumaliza kwa pamoja.

1518
01:12:24,010 --> 01:12:30,470
Hivyo nimeandika katika, # ni pamoja na
cs50.h, # stdio.h pamoja.

1519
01:12:30,470 --> 01:12:33,970
int kuu (utupu), curly brace, curly
brace, ndani ya mistari mitatu ya

1520
01:12:33,970 --> 01:12:38,760
pseudocode, kuchukua mtumiaji jina kamili,
mbili na mbili tu mstari amri

1521
01:12:38,760 --> 01:12:42,670
hoja, magazeti nje salamu kwa
user kuwa ni pamoja na majina yao ya kwanza.

1522

>> Hivyo moja ya kwanza, kuchukua
mtumiaji jina kamili.

mtumiaji jina kamili?

1524
01:12:47,290 --> 01:12:50,882

1525
01:12:50,882 --> 01:12:52,780
Jinsi gani mimi kufanya kuwa sehemu?

01:12:52,780 --> 01:12:57,685

1527
01:12:57,685 --> 01:12:59,500
Je, guys kufanya kwamba sehemu ya kwanza?

1528
01:12:59,500 --> 01:13:02,587

01:13:02,587 --> 01:13:03,894
Kuchukua user jina kamili la.

1530
01:13:03,894 --> 01:13:05,860
Naam, kwa kuwa moja ya mstari amri
hoja, nini anatakiwa kuandika?

1531
01:13:05,860 --> 01:13:09,624
Nifanye kubadilisha juu
kazi yangu tamko?

1532
01:13:09,624 --> 01:13:11,140
>> MWANAFUNZI: Wewe hawataki
kuwa ni batili tena.

1533

>> JASON HIRSCHHORN: Hasa.

1534
01:13:11,410 --> 01:13:12,385
Mimi sitaki kuwa ni batili.

1535
01:13:12,385 --> 01:13:13,630
Nini mimi nataka kuwa?

1536
01:13:13,630 --> 01:13:14,650
>> MWANAFUNZI: Int argc.

1537
01:13:14,650 --> 01:13:15,720
>> JASON HIRSCHHORN: Int argc.

1538

>> JASON HIRSCHHORN: Bracket, bracket.

1542
01:13:20,070 --> 01:13:21,780
Hiyo ni kweli kabisa, na kwamba
kweli jinsi mimi nina kwenda kupata

1543
01:13:21,780 --> 01:13:22,820
mtumiaji jina kamili.

1544
01:13:22,820 --> 01:13:24,070
Wao wanaenda kuiweka katika huko.

1546
01:13:27,720 --> 01:13:28,780
Hivyo moja hiyo kufanyika.

1547
01:13:28,780 --> 01:13:30,780
Hivyo sasa nataka mbili na mbili tu
amri line mabishano.

1548
01:13:30,780 --> 01:13:35,065
Basi Nuhu, nini ni njia moja naweza
kuangalia idadi ya amri

1549
01:13:35,065 --> 01:13:36,315
line hoja mimi?

1550
01:13:36,315 --> 01:13:39,676

1551

taarifa, hasa.

1553
01:13:42,270 --> 01:13:44,830
Je, mimi nataka kama hali?

1554
01:13:44,830 --> 01:13:48,370
>> MWANAFUNZI: Kama argc mkuu zaidi kuliko 3.

1557
01:13:58,430 --> 01:13:59,400
>> MWANAFUNZI: Rejea 1.

1558
01:13:59,400 --> 01:14:01,856
>> JASON HIRSCHHORN: Kurudi 1.

1559
01:14:01,856 --> 01:14:04,050
Je kwamba kuhakikisha nina
mbili na mbili tu?

1560
01:14:04,050 --> 01:14:07,280

1561
01:14:07,280 --> 01:14:07,820
>> MWANAFUNZI: Hapana

Nini njia moja naweza kuandika hii katika tu
mstari mmoja, au bila ya kutumia

1565
01:14:21,540 --> 01:14:23,890
na Boolean operator?

1566
01:14:23,890 --> 01:14:25,942

Hasa.

1569
01:14:29,260 --> 01:14:34,890
Hivyo kama argc si sawa na 2, kwamba
atanipa mpango huu,

1570
01:14:34,890 --> 01:14:37,250
Msako, wakati mimi kukimbia, na
kwamba atanipa ngapi

1571
01:14:37,250 --> 01:14:38,740
amri line hoja?

1572
01:14:38,740 --> 01:14:42,110
Jinsi wengi mimi kuangalia kwa?

1573
01:14:42,110 --> 01:14:42,370
>> Sorry.

1574
01:14:42,370 --> 01:14:43,400
Hebu reword kwamba.

1575
01:14:43,400 --> 01:14:46,620
Kama argc = 2, jinsi mambo mengi alifanya
mtumiaji kuandika katika upinzani?

1576
01:14:46,620 --> 01:14:47,500
>> MWANAFUNZI: Moja.

1577
01:14:47,500 --> 01:14:49,120
>> JASON HIRSCHHORN: Tu moja.

1578
01:14:49,120 --> 01:14:50,430
Hivyo kabla, walikuwa sahihi, Nuhu.

1579
01:14:50,430 --> 01:14:52,192
Nini mimi kweli haja ya kuweka huko?

1580
01:14:52,192 --> 01:14:53,640

Wale ni mbili muhimu
mambo ya kukumbuka.

Hivyo katika mwisho wetu dakika mbili kabla ya sisi
kuondoka, sisi si kupata pset mbili, lakini

1632
01:16:29,250 --> 01:16:33,585
kama nilivyosema, kama unataka kukaa baada ya
kwa dakika 10, napenda yeye furaha kwenda
