146
00:06:31,230 --> 00:06:32,960
Jekk jogħġbok tieħu vantaġġ minnhom.

147
00:06:32,960 --> 00:06:35,140
Jekk int konfuż, jien aktar minn kuntenti
biex jgħinek jispjegaw lilhom

148
00:06:35,140 --> 00:06:39,290
mod ieħor, iżda mhux ġust jekk
istudenti juru up fil-ħinijiet tal-uffiċċju,

149
00:06:39,290 --> 00:06:42,530
ma bdew xejn, u huwa
Lejl il-Ħamis u dawn qed jistennew

150
00:06:42,530 --> 00:06:45,880
l-TF li jimxu minnhom permezz ta 'kull wieħed
ħaġa għall-problema stabbilita dovut

151
00:06:45,880 --> 00:06:47,140
f'nofsinhar-jum li jmiss.

152
00:06:47,140 --> 00:06:48,300
Jagħmel sens?

153
00:06:48,300 --> 00:06:50,890
Għal darb'oħra, jekk jogħġbok jiltaqa magħna fil-nofs.

154
00:06:50,890 --> 00:06:53,230
>> U fl-aħħarnett, aspettattivi għoljin.

155
00:06:53,230 --> 00:06:58,010
Jien ser tkun kulħadd gradazzjoni li l-
fis-sezzjoni tiegħi, jew skorja tiegħek

156
00:06:58,010 --> 00:06:59,020
settijiet problema.

157
00:06:59,020 --> 00:07:01,240
Inti ma marret lura problema
zero jew wieħed għadu.

158
00:07:01,240 --> 00:07:02,250
Aħna sorry dwar dan.

159
00:07:02,250 --> 00:07:04,970
Hija ħadet us awhile biex finalment
joqgħod sezzjonijiet, u issa

160
00:07:04,970 --> 00:07:05,560
nistgħu tibda gradazzjoni.

161
00:07:05,560 --> 00:07:09,560
>> I ser tingħata lura lilek
aktar fis possibbli.

162
00:07:09,560 --> 00:07:11,890
Dawk huma wħud mill tiegħi
advisees hemmhekk.

163
00:07:11,890 --> 00:07:14,150
I ser tingħata lura lilek
aktar fis possibbli.

164
00:07:14,150 --> 00:07:18,046
U għal problema sett tnejn, aħna ser tkun fuq
iskeda u aħna ser jibda jkollna minnhom

165
00:07:18,046 --> 00:07:20,440
lilek pretty malajr wara
inti jibdluhom pulzieri

166
00:07:20,440 --> 00:07:24,130
>> Meta ikollok problema tiegħek stabbilit lura, inti
se tikseb punteġġi, kif tafu minn

167
00:07:24,130 --> 00:07:28,150
qari tal-sillabu - korrettezza,
, disinn ambitu, u stil punteġġi.

168
00:07:28,150 --> 00:07:29,760
Int ser tingħata wkoll il-kummenti.

169
00:07:29,760 --> 00:07:32,160
Il-kummenti huma aktar importanti
mill-punteġġi.

170
00:07:32,160 --> 00:07:33,780
Naħseb li huwa tajjeb li jingħad li.

171
00:07:33,780 --> 00:07:37,930
>> Punteġġi huma biss numru
minn sena sa ħames.

172
00:07:37,930 --> 00:07:38,930
Huwa diffiċli biex jinqara f'dawk.

173
00:07:38,930 --> 00:07:40,720
Huwa diffiċli li jitjieb minn dawk.

174
00:07:40,720 --> 00:07:44,460
Iżda l-kummenti se tfakkar speċifiku
affarijiet li għamilt tajjeb jew f'żoni

175
00:07:44,460 --> 00:07:48,360
inti tista 'ttejjeb fuq u jagħtuk xi
ideat għall-futur jew alternattivi

176
00:07:48,360 --> 00:07:49,160
modi ta 'nagħmlu l-affarijiet.

177
00:07:49,160 --> 00:07:52,270
>> Allura jekk jogħġbok, jekk jogħġbok, jekk jogħġbok aqra
permezz tal-kummenti.

178
00:07:52,270 --> 00:07:54,190
Nressaq ħafna ħin fis
dawk il-kummenti.

179
00:07:54,190 --> 00:07:57,190
Jekk jogħġbok aqra permezz tagħhom u ma biss
iscroll sal-qiegħ tal-

180
00:07:57,190 --> 00:08:01,890
PDF, tfittex għall-punteġġ tiegħek, jew mur online
u jsibu punteġġ tiegħek, u mbagħad jinjora

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

182
00:08:02,800 --> 00:08:03,910
Li mhux kif int
se tikseb aħjar.

183
00:08:03,910 --> 00:08:06,550
Li mhux kif int ser tiżdied
punteġġi tiegħek finalment, biss

184
00:08:06,550 --> 00:08:07,340
billi tħares lejn il-punteġġi.

185
00:08:07,340 --> 00:08:08,760
Jekk jogħġbok tħares lejn dawk il-kummenti.

186
00:08:08,760 --> 00:08:13,240
>> U tul il-linja ta 'aspettattivi għoljin,
għal darb'oħra, bħal I said, inti

187
00:08:13,240 --> 00:08:14,260
jistgħu skorja minn wieħed sa ħamsa.

188
00:08:14,260 --> 00:08:17,120
Twos, threes, u fours huma l-
maġġoranza vasta ta 'punteġġi

189
00:08:17,120 --> 00:08:17,940
int ser tkun jkollna.

190
00:08:17,940 --> 00:08:20,180
Ones u livell ta 'għajxien huma kemm verament rari.

191
00:08:20,180 --> 00:08:21,720
Hemm dejjem affarijiet
nistgħu nagħmlu aħjar.

192
00:08:21,720 --> 00:08:23,490
Kulmeta I kodiċi programm, hemm
dejjem xi ħaġa I

193
00:08:23,490 --> 00:08:24,800
seta 'jsir aħjar.

194
00:08:24,800 --> 00:08:28,740
>> Hekk milli tgħid ikollok ħamsa
il-ħin kollu fuq kollox u ma

195
00:08:28,740 --> 00:08:31,960
kollox perfett, ma naħsibx kwalunkwe
minna verament nemmnu li - jew

196
00:08:31,960 --> 00:08:34,830
nisperaw, aħna ma tagħmel dak kollu
perfetta l-ħin kollu.

197
00:08:34,830 --> 00:08:37,010
Sabiex ma jkun inkwetat jekk inti
ma jiksbu ħamsa.

198
00:08:37,010 --> 00:08:40,470
A ħamsa ma iħażżu fuq l A, ta 'erba
ma map għal fuq B, ta 'tliet ma

199
00:08:40,470 --> 00:08:42,950
mhux mappa għal fuq C. Li mhux
kif il-punteġġi jaħdmu.

200
00:08:42,950 --> 00:08:48,140
>> Bħal David qal ħafna drabi, fil-
aħħar semestru tal kollha ta 'punteġġi tiegħek u

201
00:08:48,140 --> 00:08:53,390
input mill me, TF tiegħek, jingħaqdu flimkien
u tiddetermina grad finali għalik.

202
00:08:53,390 --> 00:08:56,760
Iżda għal darb'oħra, mhuwiex ħames,
A, erba, B, eċċetera.

203
00:08:56,760 --> 00:09:01,150
Hekk jien ser ikollhom aspettattivi għoljin
għalik guys.

204
00:09:01,150 --> 00:09:03,670
Jien ser tistenna problema tajba
settijiet u jien ser tagħti

205
00:09:03,670 --> 00:09:05,010
inti feedback bħala tali.

206
00:09:05,010 --> 00:09:07,430
U mhuwiex ser ifisser li int
se tikseb grad agħar.

207
00:09:07,430 --> 00:09:09,760
Inti huma ggradati f'termini ta '
progress tiegħek minn ġimgħa

208
00:09:09,760 --> 00:09:11,260
żero sat-tmiem tal-kors.

209
00:09:11,260 --> 00:09:17,190
>> U fl-aħħarnett, f'termini ta 'għoli
aspettattivi fil-klassi, I love meta

210
00:09:17,190 --> 00:09:18,460
nies jipparteċipaw.

211
00:09:18,460 --> 00:09:23,180
Nifhem xi nies iħossuhom aktar jew
inqas komdi parteċipanti.

212
00:09:23,180 --> 00:09:26,050
Nies oħra qed jipparteċipaw
mhux billi tgħolli l-idejn tagħhom u

213
00:09:26,050 --> 00:09:27,320
jitkellem il-ħin kollu.

214
00:09:27,320 --> 00:09:30,570
Iżda aħna f'din il-klassi ser ikunu
jagħmlu ħafna problemi żgħar, ħafna

215
00:09:30,570 --> 00:09:33,770
ta 'mistoqsijiet mini, u mbagħad xi
akbar kodifikazzjoni problemi.

216
00:09:33,770 --> 00:09:36,760
Allura definittivament jaħdmu dawn l-eżerċizzji out
meta nagħmlu minnhom fuq il-kompjuter tiegħek jew fuq

217
00:09:36,760 --> 00:09:37,900
folja tal-karta.

218
00:09:37,900 --> 00:09:40,933
>> Imma jien ser jagħtik ukoll xi żmien qabel
xi ħadd qatt trid tirrispondi għal ċerti

00:09:40,933 --> 00:09:42,220
mill-mistoqsijiet nistaqsi.

220
00:09:42,220 --> 00:09:44,930
Hekk minħabba I ser jagħtuk xi żmien biex
taħseb dwarha, għaliex aħna qed tmur

221
00:09:44,930 --> 00:09:49,380
biex tagħmel affarijiet fil-imsieħba kultant,
I se jistennew kulħadd

222
00:09:49,380 --> 00:09:52,150
li jiġu ingaġġati kemmxejn.

223
00:09:52,150 --> 00:09:56,030
U għal nuqqas ta 'terminu aħjar, hemm
probabbilment se jkunu sejħa kiesaħ, li

224
00:09:56,030 --> 00:09:59,045
huwa fejn kulħadd se jkollhom ċans
biex jaħsbu dwar ir-risposta, u mbagħad

225
00:09:59,045 --> 00:10:01,150
I ser sejħa fuqek, u mbagħad
inti ser jgħidu l-risposta.

226
00:10:01,150 --> 00:10:05,200
>> Tinkwetax jew jkun jibża dwar dan.

227
00:10:05,200 --> 00:10:08,610
I ghamilt fil-passat u aħna ħadthom misjuba
li huwa ħafna aktar ta 'suċċess,

228
00:10:08,610 --> 00:10:11,810
taqra wkoll ir-riċerka edukattiva fuqha biex
jiddeterminaw jekk jew le li kienet

229
00:10:11,810 --> 00:10:12,640
tattika tajba.

230
00:10:12,640 --> 00:10:15,790
Huwa utli ħafna, speċjalment jekk inti
jagħtu lill-istudenti ħin biex jaħsbu dwar il-

231
00:10:15,790 --> 00:10:20,070
tweġibiet u ma jagħmluhom biss jiġu
out u jgħidu dan id-dritt barra l-BAT.

232
00:10:20,070 --> 00:10:22,620
Imma jekk ma tħossokx komdu
tweġib, jien ukoll pjuttost tajba fil

233
00:10:22,620 --> 00:10:25,370
sensing li minn, u aħna ma tkunx qed tmur biex
tpoġġi lilek fuq il-post, speċjalment fuq

234
00:10:25,370 --> 00:10:28,240
il-camera, minkejja li ebda waħda
inti fuq camera dritt issa.

235
00:10:28,240 --> 00:10:32,250
>> Għalhekk dawn huma l-normi I jkollhom.

236
00:10:32,250 --> 00:10:34,670
Ħaġa waħda aktar fuq il-linji
tal-laqgħa fin-nofs.

237
00:10:34,670 --> 00:10:36,490
Jien ser jagħtuk guys
ħafna ta 'feedback.

238
00:10:36,490 --> 00:10:38,310
Jekk jogħġbok agħtini feedback ukoll.

Hemm website, sayat.me/cs50.

00:10:46,190 --> 00:10:48,380
Allura huwa ta 'feedback onest.

241
00:10:48,380 --> 00:10:50,730
Jekk inti tixtieq li tagħti lilha matul it-taqsima,
I nikseb email kull meta dan jiġri.

242
00:10:50,730 --> 00:10:53,820
Aħna ser jieħu pawża fil-daqsxejn, so I ser
tfittex permezz tal-feedback imbagħad.

243
00:10:53,820 --> 00:10:55,970
Jekk qatt ikollok xi feedback,
jekk jogħġbok agħti lili hemm.

244
00:10:55,970 --> 00:11:01,380
>> Jekk inti tagħti me feedback fuq il-Q, li
wunderbare, iżda li l-gwida

245
00:11:01,380 --> 00:11:02,570
li inti tagħmel fl-aħħar.

246
00:11:02,570 --> 00:11:05,690
Iżda dan se jkun fl-aħħar semestru hekk
I mhux se jkunu jistgħu jieħdu xi li

I imħabba feedback.

Lura għall FOP, irridu jiksbu feedback
il-ħin kollu.

00:11:18,610 --> 00:11:20,600
Tista 'tikkummenta fuq ħwejjeġ tiegħi.

253
00:11:20,600 --> 00:11:24,170
Li mhux se jkun utli, imma int
merħba lill jikkummentaw dwar kwalunkwe u

00:11:33,280 --> 00:11:34,530
Aħna ser ikollhom ta 'gost.

00:11:34,530 --> 00:11:36,930
Nisperaw f'dan il-kors, inti ser
għandhom ħafna gost.

261
00:11:36,930 --> 00:11:38,780
Aħna ser ikollhom kandju fit-taqsima.

00:11:38,780 --> 00:11:40,040
Aħna ser ikollhom mużika.

263
00:11:40,040 --> 00:11:45,510
Aħna se nisperaw jkollna jafu lil
ieħor kemmxejn ukoll, so I jridu

jkun il-każ issa.

267
00:11:53,750 --> 00:11:55,960
U jekk huwa l-każ issa, biss
ma snore minħabba li jistgħu

268
00:11:55,960 --> 00:11:57,580
tkun maqbuda fuq camera.

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

Kwalunkwe mistoqsijiet, kummenti, jew tħassib
qabel I jimxu fuq dwar xi ħaġa konna

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

>> Allura aħna qed tmur biex jmorru
fis arrays ewwel.

Din hija kif inti tagħmel firxa.

276
00:12:17,140 --> 00:12:18,410
Rajna dan qabel.

277
00:12:18,410 --> 00:12:21,830
Għandek tip data, inti għandek
isem, u allura inti jkollhom daqs.

278
00:12:21,830 --> 00:12:24,430
Dritt hawn, I joħolqu żewġ arrays.

279
00:12:24,430 --> 00:12:30,360
L-ewwel waħda hija firxa ta 'karattri,
u għandha 26-kmamar.

280
00:12:30,360 --> 00:12:33,790
It-tieni waħda hija firxa ta '
punteġġi, u għandu tliet

281
00:12:33,790 --> 00:12:35,390
spazji għal tliet numri interi.

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

Il-kwistjoni kienet, huma kollha ta '

Iva.

287

Kollha ta 'dawn slides ser ikunu disponibbli,

289
00:12:44,640 --> 00:12:47,340
Imma llum, għaliex dan huwa l-ewwel
ġimgħa, kellna bidu tard.

290
00:12:47,340 --> 00:12:49,675
Allura normalment, int ser tingħata dawn slides, iżda
dawn se jkunu disponibbli online u

291
00:12:49,675 --> 00:12:52,420
I ser email lilek
dritt wara klassi.

292
00:12:52,420 --> 00:12:54,140
Kwalunkwe mistoqsijiet oħra?

293
00:12:54,140 --> 00:13:01,330
>> Għalhekk għal darb'oħra, arrays huma kaxxi, għal nuqqas ta '
aħjar kelma, li jżommu multipli

294
00:13:01,330 --> 00:13:06,420
elementi ta 'dejta tat-tip waħda, u dawn qed
li jmiss ma 'xulxin fil-memorja.

295
00:13:06,420 --> 00:13:11,370
U għalhekk għal darb'oħra, dan huwa kif inti tista '
jagħmlu żewġ tipi ta 'arrays.

296
00:13:11,370 --> 00:13:15,090
>> Allura wara li tkun ħadthom magħmula firxa tiegħek ma
li l-ewwel linja - punteġġi int, parentesi

297
00:13:15,090 --> 00:13:17,430
tlieta, parentesi magħluqa - inti
tixtieq li initialize dan.

298
00:13:17,430 --> 00:13:19,050
Inti tixtieq li tqiegħed xi valuri fil hemmhekk.

299
00:13:19,050 --> 00:13:24,660
U dan huwa kif inti tpoġġi xi valuri fil
hemm, biss jagħżlu l-indice u

300
00:13:24,660 --> 00:13:25,670
jitniżżel in-numru.

301
00:13:25,670 --> 00:13:27,130
Ejja tiġbed fuq il-bord.

302
00:13:27,130 --> 00:13:28,270
Jista 'jara kulħadd?

303
00:13:28,270 --> 00:13:29,030
Kulħadd jista 'jara.

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

305
00:13:30,790 --> 00:13:36,550
>> Allura li għaddej biex tkun tiegħi
array imsejħa Scores.

306
00:13:36,550 --> 00:13:37,730
Kif tistgħu taraw, huwa daqs tlieta.

307
00:13:37,730 --> 00:13:39,210
Hemm tliet kaxxi fil hemmhekk.

308
00:13:39,210 --> 00:13:43,120
Kull wieħed jistgħu joqogħdu liema
tip ta 'tip ta' dejta?

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

310
00:13:43,790 --> 00:13:45,250
>> JASON Hirschhorn: Integer
f'dan il-wieħed.

311
00:13:45,250 --> 00:13:48,790
Aħna kiteb punteġġi int, u l-ewwel kelma
hija t-tip data li għaddej biex

312
00:13:48,790 --> 00:13:50,910
jmorru fil-kaxxi f'dak array.

313
00:13:50,910 --> 00:13:52,160
So I jistgħu joqogħdu tlieta.

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

315
00:13:54,880 --> 00:13:57,000
Għaliex għandi zero up
hemm fuq il-bord?

316
00:13:57,000 --> 00:13:59,240
Għaliex ma jgħidu punteġġ żero daqs 1?

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

318
00:14:02,090 --> 00:14:03,180
Ifakkru lili ta 'ismek.

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

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

321
00:14:04,070 --> 00:14:04,480
>> STUDENT: Iva.

322
00:14:04,480 --> 00:14:04,920
>> JASON Hirschhorn: Għaliex?

323
00:14:04,920 --> 00:14:07,230
>> STUDENT: Minħabba li l-ewwel indiċi
żero, nibdew jingħaddu żero.

324
00:14:07,230 --> 00:14:08,480
>> JASON Hirschhorn: Allura nibdew
għadd żero.

325
00:14:08,480 --> 00:14:09,580
Dan huwa eżattament id-dritt.

326
00:14:09,580 --> 00:14:12,340
Dan huwa l-parti konfuża u vjaġġ rieda
inti up, speċjalment meta int

327
00:14:12,340 --> 00:14:14,900
jippruvaw jtenni permezz arrays,
li aħna ser nagħmlu fi ftit.

328
00:14:14,900 --> 00:14:15,980
Nibdew jingħaddu żero.

329
00:14:15,980 --> 00:14:19,170
Mela jekk jien tixtieq li jirreferu għall-ewwel
kaxxa, mhuwiex kaxxa waħda.

330
00:14:19,170 --> 00:14:22,290
Sfortunatament, huwa kaxxa żero.

331
00:14:22,290 --> 00:14:26,460
It-tieni waħda hija kaxxa waħda, u f'dan il-
każ, it-tielet wieħed huwa kaxxa tnejn.

332
00:14:26,460 --> 00:14:28,700
>> What about kaxxa tliet?

333
00:14:28,700 --> 00:14:30,670
Fejn hi kaxxa tliet?

334
00:14:30,670 --> 00:14:34,750
Jew jekk nixtieq do punteġġi, parentesi
tlieta, parentesi magħluqa, dak li?

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

336
00:14:37,650 --> 00:14:39,760
Allura inti qal li l-karattru null.

337
00:14:39,760 --> 00:14:41,600
Kwalunkwe ħsibijiet oħra?

338
00:14:41,600 --> 00:14:44,590
X'inhu bracket score tliet bracket?

339
00:14:44,590 --> 00:14:48,045
>> STUDENT: Hija ma verament jeżistu minħabba
inti biss definiti bħala punteġġi,

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

341
00:14:49,370 --> 00:14:51,400
>> JASON Hirschhorn: Allura inti tgħidli
ma verament jeżistu.

342
00:14:51,400 --> 00:14:54,230
F'xi każijiet, meta aħna qed jittrattaw ma '
kordi, ġeneralment aħna ser ipoġġi null

343
00:14:54,230 --> 00:14:54,790
karattru fl-aħħar.

344
00:14:54,790 --> 00:14:56,100
Aħna ser jiksbu għal dak fit-tieni.

345
00:14:56,100 --> 00:15:01,020
Iżda f'dan il-każ, hemm
ebda tielet kaxxa hawn.

346
00:15:01,020 --> 00:15:06,390
Allura l-aħħar kaxxa fi kwalunkwe firxa
huwa d-daqs minus 1.

347
00:15:06,390 --> 00:15:11,310
Hekk jekk għandna firxa ta 'n daqs, il-
ewwel kaxxa hija żero, l-aħħar wieħed huwa

348
00:15:11,310 --> 00:15:12,700
fi n minus 1.

349
00:15:12,700 --> 00:15:14,970
U f'dan il-każ, dan ma jeżistix.

350
00:15:14,970 --> 00:15:17,970
Hemm xi ħaġa hawn
memorja iżda mhux tagħna.

351
00:15:17,970 --> 00:15:18,460
Aħna ma stess dan.

352
00:15:18,460 --> 00:15:19,570
Aħna ma jistaqsu għaliha.

353
00:15:19,570 --> 00:15:22,606
Hekk jekk nippruvaw li jkollhom aċċess għaliha, li aħna ser
jagħmlu fi ftit, aħna qed probabbilment se

354
00:15:22,606 --> 00:15:24,970
jsibu rwieħhom trouble.

355
00:15:24,970 --> 00:15:29,180
>> F'dan il-każ, jien initializing tiegħi
array bi tliet varjabbli.

356
00:15:29,180 --> 00:15:36,195
Aħna qed tqegħid waħda fil-kaxxa żero, ta 'żewġ
f'kaxxa waħda, u tlieta fil-kaxxa tnejn.

357
00:15:36,195 --> 00:15:39,280
Ħadd ma jkollu xi mistoqsijiet
dwar initializing firxa?

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

359
00:15:44,540 --> 00:15:46,970
>> Allura aħna marru fuq dan biss issa.

360
00:15:46,970 --> 00:15:52,725
Punteġġi, parentesi tlieta, parentesi qrib,
li ma teżistix.

361
00:15:52,725 --> 00:15:58,130
Aħna żero indiċjati fix-xjenza tal-kompjuter,
hekk nibdew jingħaddu żero.

362
00:15:58,130 --> 00:16:01,860
L-aħħar kaxxa disponibbli lilna, huwa
it-tielet kaxxa, iżda huwa msejjaħ kaxxa

363
00:16:01,860 --> 00:16:03,110
numru tnejn.

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

365
00:16:05,790 --> 00:16:09,710
>> Stabbiliti hawn taħt, din hija alternattiva
mod ta 'initializing arrays.

366
00:16:09,710 --> 00:16:13,410
Allura minflok ma jinħolqu l-array fuq waħda
linja, timla l-ewwel kaxxa, imbagħad

367
00:16:13,410 --> 00:16:17,070
it-tieni kaxxa, imbagħad it-tielet kaxxa,
inti tista 'tagħmel dan kollu f'linja waħda.

368
00:16:17,070 --> 00:16:19,040
Allura f'dak il-linja, iż-żewġ arrays.

369
00:16:19,040 --> 00:16:23,460
Dan joħloq l-istess firxa eżatt bħal
dak li ħloqna dritt hawn, iżda

370
00:16:23,460 --> 00:16:24,710
biss ma huwa f'linja waħda.

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

372
00:16:29,740 --> 00:16:31,360
>> Issa ħloqna firxa tagħna.

373
00:16:31,360 --> 00:16:34,100
Normalment ladarba inti toħloq firxa, inti
trid tagħmel xi ħaġa ma 'dan, jekk

374
00:16:34,100 --> 00:16:38,430
thats imla jew tikseb affarijiet minnha
u tipprintjahom fuq l-iskrin.

375
00:16:38,430 --> 00:16:42,270
F'dan il-każ, aħna qed tmur permezz tagħna
punteġġi array, li aħna initialized fuq

376
00:16:42,270 --> 00:16:44,740
l-ewwel linja up hawn fil-griż.

377
00:16:44,740 --> 00:16:49,600
U mbagħad fit-tieni linja, nibdew
iterazzjoni permezz tal-firxa.

378
00:16:49,600 --> 00:16:52,640
Ħadd ma jkollu xi mistoqsijiet dwar
l-istruttura ta 'għall-loop?

dan il-programm?

385
00:17:06,290 --> 00:17:10,410
Jista 'xi ħadd tell me dak li aħna se tikseb?

Stylistically, huwa ġeneralment inqas minn,
u tkun taf tara fit-tieni meta

594
00:27:44,780 --> 00:27:48,160
aħna kordi, inti tista 'tuża xi ħaġa
imsejħa strlen, li inti stajt tidher

595
00:27:48,160 --> 00:27:50,380
qabel, biex jiksbu l-tul
tas-sekwenza.

596
00:27:50,380 --> 00:27:54,090
U inti ma tistax tagħmel inqas minn
jew ugwali strlen.

597
00:27:54,090 --> 00:27:56,500
Inti tista 'tagħmel inqas minn jew
ugwali strlen barra wieħed.

598
00:27:56,500 --> 00:27:59,260
Allura huwa biss nicer li
tagħmel inqas minn strlen.

599
00:27:59,260 --> 00:28:00,240
Iva?

600
00:28:00,240 --> 00:28:03,270

għandhom jipprovdu l-kummenti?

604
00:28:07,760 --> 00:28:12,050
Allura aħna ser nitkellmu aktar dwar kwizzijiet meta
dawn jiġu, iżda ġeneralment, tajba

605
00:28:12,050 --> 00:28:14,530
regola ġenerali hija meta int
kodiċi miktub, tipprovdi kummenti.

606
00:28:14,530 --> 00:28:18,130
Jekk ikollok l-kodiċi ħażin, iżda l-
jikkummentaw dritt, inti tista 'tikseb xi

607
00:28:18,130 --> 00:28:22,280
kreditu kemm mill me jekk I kien gradazzjoni
inti fuq sett problema jew fuq kwizz.

608
00:28:22,280 --> 00:28:24,660
Allura kummenti huma dejjem
tajba biex jipprovdu.

Rajna dan qabel fil lecture.

616
00:28:31,730 --> 00:28:33,390
Dan nefaħ my mind meta I
ewwel jinstab dan out.

617
00:28:33,390 --> 00:28:37,240
Huwa probabbilment ma blow l ħadd

huwa dan il-karattru / 0.

620
00:28:45,710 --> 00:28:47,740
Jekk aħna qed tmur biex jiġbed string fuq il-

622
00:28:53,080 --> 00:28:56,420

623
00:28:56,420 --> 00:28:56,680
Jiddispjacini.

624
00:28:56,680 --> 00:28:57,660

Għaliex huwa erba?

628

huwa għall-karattru null.

huwa għall-karattru null.

630
00:29:04,070 --> 00:29:07,130
Mela jekk jien kienu li jimxu fuq strlen
dan, dan jagħti me erbgħa.

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

632
00:29:07,850 --> 00:29:11,640

>> JASON Hirschhorn: ħames.

636
00:29:14,200 --> 00:29:17,650
I jkollhom jistaqsu għal ħames, iżda nista '
biss jitqiegħdu erba 'karattri fil hawn

minħabba I bżonn li titqiegħed li null
terminatur fuq l-aħħar.

638
00:29:19,750 --> 00:29:25,260
Allura aħna qed tmur biex jiktbu fil-"ohai" u
tpoġġi l-terminatur null fl-aħħar.

762
00:35:13,660 --> 00:35:13,770
>> JASON Hirschhorn: virgola.

763
00:35:13,770 --> 00:35:14,380
Fantastic.

764
00:35:14,380 --> 00:35:16,890
Mela ejja Ħlief dan.

765
00:35:16,890 --> 00:35:19,770
Jagħmlu jespliċitaw.

766
00:35:19,770 --> 00:35:20,040
Oh boy.

767
00:35:20,040 --> 00:35:22,275
Stajt ltqajna koppja ta 'żbalji.

768
00:35:22,275 --> 00:35:33,120
Ewwel żball fuq il-linja 11, li jgħid,
espressjoni mistennija, u huwa jagħti

769
00:35:33,120 --> 00:35:36,910
me żball li t-tieni
int, hemm l-iżball.

770
00:35:36,910 --> 00:35:38,430
Hemm xi żball madwar hemmhekk.

771
00:35:38,430 --> 00:35:41,060
Ħadd ma jaf dak iżball li hu?

772
00:35:41,060 --> 00:35:41,640
Kurt?

773
00:35:41,640 --> 00:35:44,108
>> STUDENT: Naħseb huwa suppost
jkun virgola u mhux punto virgola.

774
00:35:44,108 --> 00:35:46,010
>> JASON Hirschhorn: OK, comma
minflok virgola.

775
00:35:46,010 --> 00:35:47,340
Allura hija li aħna lkoll jeħtieġ li jiffissaw?

776
00:35:47,340 --> 00:35:47,655
>> STUDENT: Le

777
00:35:47,655 --> 00:35:48,930
>> JASON Hirschhorn: X'iktar
għandna bżonn biex jiffissaw?

778
00:35:48,930 --> 00:35:50,920
>> STUDENT: Irridu jinkludu string.h.

779
00:35:50,920 --> 00:35:51,680
>> JASON Hirschhorn: Inkludi string.h.

780
00:35:51,680 --> 00:35:53,730
Fejn għandi bżonn biex tinkludi li?

781
00:35:53,730 --> 00:35:57,085
>> STUDENT: L-istess post int inklużi
l-għalf ieħor, id-dritt

782
00:35:57,085 --> 00:35:59,560
wara jinkludu stdio.h.

783
00:35:59,560 --> 00:36:01,610
>> JASON Hirschhorn: Ejja naraw jekk dan imur
ewwel għaliex ġeneralment, I simili

784
00:36:01,610 --> 00:36:06,360
li tiffissa ħaġa waħda ewwel, u mbagħad għaddi
dan, u mbagħad tara l-iżbalji nikbru.

785
00:36:06,360 --> 00:36:11,620
Allura aħna qed tmur biex ċar-terminal
mal-kontroll n, ejja do jagħmlu jespliċitaw.

786
00:36:11,620 --> 00:36:15,190

787
00:36:15,190 --> 00:36:18,770
Allura żball ieħor fuq il-linja 11.

788
00:36:18,770 --> 00:36:20,540
Virgola mistenni.

789
00:36:20,540 --> 00:36:22,640
U jien xorta jkollna
żbalji fuq din il-linja.

790
00:36:22,640 --> 00:36:25,270
Għalhekk ma tatx me żball li tgħid li huwa
ma jifhimx dak strlen hi,

791
00:36:25,270 --> 00:36:28,980
iżda qed tagħti me żbalji fuq dan
linja, hekk x'iktar hu ħażin?

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

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

794
00:36:30,940 --> 00:36:32,570
>> STUDENT: Għandek biex jitneħħew
it-tieni dikjarazzjoni int?

795
00:36:32,570 --> 00:36:34,990
>> JASON Hirschhorn: Neħħi
it-tieni int.

796
00:36:34,990 --> 00:36:35,710
Ejja nippruvaw dan.

797
00:36:35,710 --> 00:36:37,600
Issa ċar l-terminal.

798
00:36:37,600 --> 00:36:40,130
Jagħmlu jespliċitaw.

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

800
00:36:40,490 --> 00:36:42,890
Impliċitament tiddikjara librerija
funzjoni strlen.

801
00:36:42,890 --> 00:36:44,270
Allura issa aħna ma tara dan l-iżball.

802
00:36:44,270 --> 00:36:45,760
What do we bżonn li jinkludu?

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

804
00:36:46,660 --> 00:36:51,880

tal-iskrin.

806
00:36:52,920 --> 00:36:55,450
Ejja ħlief, jagħmlu jespliċitaw.

807
00:36:55,450 --> 00:36:56,970
Issa miġbura.

808
00:36:56,970 --> 00:37:01,970
Għalhekk għal darb'oħra, l-affarijiet aħna meħtieġa biex
ftakar linja 12 fil loop għall tagħna meta

809
00:37:01,970 --> 00:37:08,010
aħna qed istabbiliment tiegħu, i int = 0,
tul = strlen (i).

810
00:37:08,010 --> 00:37:09,350
>> Din hija strateġija meraviljuż.

811
00:37:09,350 --> 00:37:12,590
L-istil ta 'dan huwa kbir, il-
disinn ta 'dan huwa kbir.

812
00:37:12,590 --> 00:37:15,620
Aħna tista 'tmur fil dawn ir-raġunijiet aktar tard,
iżda dan il-mod inti għandek bżonn biss sabiex jikkonfutaw

813
00:37:15,620 --> 00:37:19,040
strlen darba minflok kull waħda
ħin inti tmexxi permezz tal-linja.

814
00:37:19,040 --> 00:37:22,255
Madankollu, jeħtieġ li tuża comma hemm
u inti m'għandekx bżonn int ġdid.

815
00:37:22,255 --> 00:37:24,180
Jekk int tiddikjara kemm dawk
varjabbli flimkien, inti

816
00:37:24,180 --> 00:37:26,850
m'għandhomx bżonn int ġdid.

817
00:37:26,850 --> 00:37:29,820
U mbagħad jekk int ser tuża strlen,
li hija librerija ieħor

818
00:37:29,820 --> 00:37:33,560
jiffunzjonawx mhux inklużi fl-
stdio.h jew cs50.h, jagħmlu

819
00:37:33,560 --> 00:37:35,310
ruħek li jinkludu string.h.

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

821
00:37:35,900 --> 00:37:39,085
>> STUDENT: Mela allura jekk inti m'għandekx bżonn li
jgħidu dak tul tip huwa, ma li

822
00:37:39,085 --> 00:37:40,290
jfissirx li għandu jkun hemm int?

823
00:37:40,290 --> 00:37:41,930
Inti ma jista 'jkollha żewġ differenti
tipi hemmhekk?

824
00:37:41,930 --> 00:37:43,290
>> JASON Hirschhorn: Allura inti tista
għandhom żewġ tipi differenti.

825
00:37:43,290 --> 00:37:45,730
Tul huwa int hawn, għalkemm.

826
00:37:45,730 --> 00:37:48,590
Tul huwa int għaliex dan huwa comma
u allura l-istess ħaġa.

827
00:37:48,590 --> 00:37:50,460
>> STUDENT: Allura li jassumi li huwa se
jkun l-istess bħall-ewwel waħda?

828
00:37:50,460 --> 00:37:52,423
>> JASON Hirschhorn: Eżattament.

829
00:37:52,423 --> 00:37:54,970
Aħna mhux se tagħmel dan issa, imma int
jistgħu jinkludu żewġ varjabbli fuq il-

830
00:37:54,970 --> 00:37:57,080
istess linja jużaw tip ta 'data waħda.

831
00:37:57,080 --> 00:38:01,415
X Allura int, y toħloq
żewġ varjabbli.

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

833
00:38:05,830 --> 00:38:10,770
Allura x int, y, jekk nagħmlu dan, tagħti
me x varjabbli mhux użati uy minħabba

834
00:38:10,770 --> 00:38:12,020
aħna ma jużawhom.

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

836
00:38:17,950 --> 00:38:21,650
Allura tqegħid null qabel hija biss
trick fancy jekk inti ma tuża

837
00:38:21,650 --> 00:38:22,810
xi ħaġa, li jużawh.

838
00:38:22,810 --> 00:38:26,300
Imma kif tara, I joħolqu xuy
fuq l-istess linja b'virgola.

839
00:38:26,300 --> 00:38:28,450
Huwa ħolqien ta 'żewġ numri interi
hemm dritt.

840
00:38:28,450 --> 00:38:31,560
Allura iva, totalment possibbli li jinħolqu
żewġ affarijiet fuq l-istess linja

841
00:38:31,560 --> 00:38:33,720
separati b'virgola.

00:38:39,200 --> 00:38:43,040
Ejjew nagħmluha waħda aktar ħin, run.

846
00:38:43,040 --> 00:38:44,580
Agħti me string.

852
00:38:52,810 --> 00:38:53,700
Jistenna kbira.

853
00:38:53,700 --> 00:38:54,750
Ejja run mill-ġdid.

854
00:38:54,750 --> 00:38:56,050
Dejjem se jiċċekkja
għal każijiet kantuniera.

855
00:38:56,050 --> 00:38:57,750
X'hemm każ kantuniera tajba biex jiċċekkjaw?

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

So I ser jitqiegħdu fil-1, u tistampa 1.

860
00:39:06,580 --> 00:39:08,970
Huwa ma talbitx għal ittri, hekk
jidher li huwa simili numri xogħol.

861
00:39:08,970 --> 00:39:09,890
Każ kantuniera tajba biex jiċċekkjaw.

862
00:39:09,890 --> 00:39:11,740
X'hemm kantuniera tajjeb ieħor
fajl sabiex tiġi vverifikata?

863
00:39:11,740 --> 00:39:12,420
>> STUDENT: A string vojt.

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

865
00:39:12,910 --> 00:39:13,880
>> STUDENT: Bħal string vojt.

866
00:39:13,880 --> 00:39:14,400
>> JASON Hirschhorn: string vojta.

867
00:39:14,400 --> 00:39:16,730
Mela ejja ma jitqiegħdu fil-xejn.

868
00:39:16,730 --> 00:39:18,660
U dak gets stampata?

869
00:39:18,660 --> 00:39:19,090

Tidher bħal taħdem.

872
00:39:20,555 --> 00:39:23,790
Inti tista 'tipprova każijiet kantuniera aktar, iżda
ġeneralment numri, a data differenti hija

873
00:39:23,790 --> 00:39:26,160
kbira li jippruvaw, kif ukoll xejn.

874
00:39:26,160 --> 00:39:29,180
Xejn, żero, negattivi huma dejjem
affarijiet kbar li tipprova affarijiet li inti

875
00:39:29,180 --> 00:39:33,140
Għandu test, l-affarijiet żgur aħna ser test
għal u Iċċekkja 50 se tittestja għal.

876
00:39:33,140 --> 00:39:34,720
Kwalunkwe mistoqsijiet dwar spell.c?

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

Huwa sejjaħ students.c.

881
00:39:44,700 --> 00:39:49,020
Dan huwa programm li jitlob lill-utent għall-
ħames ismijiet, allura jagħżel bl-addoċċ

882
00:39:49,020 --> 00:39:51,600
u tistampa wieħed mill-ismijiet.

883
00:39:51,600 --> 00:39:54,840
Dan il-programm huwa ftit aktar
involuti mill-aħħar tnejn aħna kiteb,

884
00:39:54,840 --> 00:39:58,080
hekk għaliex ma nieħdu ħames minuti biex
kodiċi hija individwalment, u mbagħad aħna ser

885
00:39:58,080 --> 00:40:00,130
kodiċi minnu bħala grupp.

886
00:40:00,130 --> 00:40:03,795

inti tista 'ma raw qabel, hekk jekk

887
00:40:03,795 --> 00:40:06,390
għandek xi mistoqsija dwar, kif jagħmlu
I tagħmel dan, jgħollu naħa tiegħek.

888
00:40:06,390 --> 00:40:08,530
I ser jiġi maż u punt inti
fid-direzzjoni t-tajba.

889
00:40:08,530 --> 00:40:10,820
Iżda aħna wkoll qed tagħmel dan għaliex dan
se tkun mod tajjeb biex jintroduċu xi

890
00:40:10,820 --> 00:40:12,070
suġġetti li huma delikata.

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

problema sett, hemm ħafna modi biex tagħmel

895
00:44:19,180 --> 00:44:20,790
dan, iżda xi wħud huma aktar
eleganti minn oħrajn.

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

897
00:44:29,000 --> 00:44:31,110
Let us adsa pulzieri

Ġewwa l-ċingi kaboċċi,
Għandi żewġ kummenti.

902
00:44:39,430 --> 00:44:41,500
L-ewwel wieħed huwa, titlob lill-
utent għal ħames ismijiet.

903
00:44:41,500 --> 00:44:46,580
It-tieni wieħed huwa, jagħżlu saltwarjament
u jistampa wieħed mill-ismijiet.

904
00:44:46,580 --> 00:44:50,250
Mela ejja jagħmlu l-ewwel waħda, staqsi
l-utent għall-ħames ismijiet.

905
00:44:50,250 --> 00:44:53,730
Li jkun staqsa l-utent għall-ħames ismijiet
u tista 'tgħidli kif għandek tagħmel dan?

906
