00:00:00,000 --> 00:00:09,386

2
00:00:09,386 --> 00:00:11,332
>> ZAMYLA CHAN: Hebu na
furaha na kumi na tano.

3
00:00:11,332 --> 00:00:15,680
Kumi na tano ni mchezo wa kwanza kupata
kutekeleza na ni mwingiliano.

4
00:00:15,680 --> 00:00:16,410
Sasa, si kuwa na wasiwasi.

5
00:00:16,410 --> 00:00:18,830
Huna kuandika
jambo zima mwenyewe.

6
00:00:18,830 --> 00:00:22,320
Angalia katika usambazaji code kwa sababu
mengi ya muundo mchezo ni tayari

7
00:00:22,320 --> 00:00:23,880
kuanzisha kwa ajili yenu.

8
00:00:23,880 --> 00:00:28,160
Ni anapokea na parses amri line
hoja kutoka kwa mtumiaji na inajenga

9
00:00:28,160 --> 00:00:31,230
bodi ya msingi juu ya pembejeo kwamba.

10
00:00:31,230 --> 00:00:35,570
Ni hundi ya kama mchezo ni mshindi na exits
mara moja mtumiaji alishinda mchezo.

11
00:00:35,570 --> 00:00:38,340
Na kushinda mchezo, anapata
pembejeo kutoka kwa mtumiaji na

12
00:00:38,340 --> 00:00:40,610
wito Hoja kazi.

13
00:00:40,610 --> 00:00:44,600
>> Hivyo sisi ni kwenda kwa kuwa utekelezaji nne
kazi kwa ajili ya mchezo wa kumi na tano,

14
00:00:44,600 --> 00:00:48,110
init, kuteka, hoja, na alishinda.

15
00:00:48,110 --> 00:00:50,340
Kwanza, hebu kukabiliana na init.

16
00:00:50,340 --> 00:00:55,150
Katika init, kwa initialize, sisi kuwakilisha
bodi katika P2 integer safu.

17
00:00:55,150 --> 00:01:01,070
Na hii ni variable kimataifa aitwaye
bodi na vipimo MAX, na MAX,

18
00:01:01,070 --> 00:01:03,880
vipimo upeo wa bodi.

19
00:01:03,880 --> 00:01:07,310
Sasa, mwelekeo halisi wa bodi
ni kutolewa kwa mtumiaji, kuwakilishwa katika

20
00:01:07,310 --> 00:01:10,620
integer d, ambayo inaweza
kuwa chini ya MAX.

21
00:01:10,620 --> 00:01:14,660
Lakini, katika C, huwezi resize arrays,
hivyo wewe ni kukwama kwa

22
00:01:14,660 --> 00:01:16,730
kwamba mwelekeo wa kiwango cha juu.

23
00:01:16,730 --> 00:01:19,870
>> Kazi yako katika init ni na idadi ya
maadili ya bodi

24
00:01:19,870 --> 00:01:21,860
kwa thamani sahihi.

25
00:01:21,860 --> 00:01:26,910
Sasa, tumeona arrays 1D, lakini
jinsi gani arrays P2 kazi?

26
00:01:26,910 --> 00:01:30,985
Kuna ripoti ya mstari, sifuri
indexed kama siku zote, na kisha pia ya

27
00:01:30,985 --> 00:01:32,100
safu.

28
00:01:32,100 --> 00:01:36,120
Na wewe utakuwa kujaza gridi yako katika katika
kushuka maadili, tu kama hii.

29
00:01:36,120 --> 00:01:43,260
Gridi ya taifa, 0, 0, mstari 0, safu
0, ni 8, gridi ya taifa 0, 1 ni 7.

30
00:01:43,260 --> 00:01:48,500
Hii ni kwa mfano ambapo
d, kidogo d, ni 3.

31
00:01:48,500 --> 00:01:52,690
>> Sasa, bodi katika kumi na tano lazima pia
vyenye tile tupu, kama wameweza milele

32
00:01:52,690 --> 00:01:54,280
alicheza na mchezo kimwili.

33
00:01:54,280 --> 00:01:59,210
Lakini, bodi ni integer safu, hivyo
maadili yote kuwa integers.

34
00:01:59,210 --> 00:02:06,950
Hivyo ni juu yako kuamua integer
thamani ya kuwakilisha tile tupu.

35
00:02:06,950 --> 00:02:10,460
Initialize bodi yako, unaweza kutumia
miundo kitanzi na vyenye

36
00:02:10,460 --> 00:02:16,440
kuanzia hali ya bodi, ambapo bodi
i j inawakilisha kipengele katika

37
00:02:16,440 --> 00:02:19,380
mstari i na safu j.

38
00:02:19,380 --> 00:02:23,035
Wao kuanza ili kushuka na,
kumbuka kwamba, kama idadi ya matofali

39
00:02:23,035 --> 00:02:29,590
ni isiyo ya kawaida, basi wewe ni kwenda na
kubadilishana eneo la 2 na ya 1.

40
00:02:29,590 --> 00:02:33,790
Kwa hiyo, kuna, tuna yetu
kuanzishwa bodi.

41
00:02:33,790 --> 00:02:37,440
>> Sasa, kwamba tumekuwa kuanzishwa wetu
bodi, ni wakati wa kuteka ni.

42
00:02:37,440 --> 00:02:41,260
Draw magazeti hali ya sasa ya
bodi, lakini unahitaji kuhakikisha

43
00:02:41,260 --> 00:02:44,260
magazeti tiles katika utaratibu huo
kwamba umefanya kuanzishwa yao.

44
00:02:44,260 --> 00:02:47,300
Na wewe pia haja ya muundo
idadi yako kwa usahihi.

45
00:02:47,300 --> 00:02:51,700
Kwa sababu sisi kuwa na tarakimu moja na
tarakimu mbili, kisha unataka

46
00:02:51,700 --> 00:02:54,540
magazeti nafasi tupu kabla ya
yoyote ile moja namba za tarakimu.

47
00:02:54,540 --> 00:03:00,150
Unaweza kutumia kwa kutumia
placeholder -.

48
00:03:00,150 --> 00:03:02,550
>> Lakini kumbuka nafasi yetu tupu.

49
00:03:02,550 --> 00:03:05,970
Hatutaki magazeti idadi halisi
kwamba tumekuwa waliochaguliwa kuwakilisha

50
00:03:05,970 --> 00:03:10,410
kwamba nafasi tupu katika bodi, lakini sisi pia
hawataki magazeti kitu.

51
00:03:10,410 --> 00:03:15,310
Hivyo nini unaweza kufanya ni kufafanua ishara
au tabia ya kuwakilisha

52
00:03:15,310 --> 00:03:17,050
tupu tile.

53
00:03:17,050 --> 00:03:21,030
Katika mifano uliopita nimekuwa waliochaguliwa
kusisitiza, na kisha tu magazeti

54
00:03:21,030 --> 00:03:26,970
kwamba wakati wowote kufikia tupu
nafasi kwa sare ya kazi yako.

55
00:03:26,970 --> 00:03:29,850
>> Hivyo kuteka itakuwa Furushi kwa matanzi.

56
00:03:29,850 --> 00:03:31,150
Kitu kama hiki.

57
00:03:31,150 --> 00:03:35,660
Kwa kila safu, na kisha kwa kila thamani katika
mstari, wewe ni kwenda magazeti

58
00:03:35,660 --> 00:03:36,940
thamani katika nafasi hii.

59
00:03:36,940 --> 00:03:39,470
Mara moja umefanya kuchapishwa maadili yote
katika mstari, basi

60
00:03:39,470 --> 00:03:41,180
unaweza magazeti line mpya.

61
00:03:41,180 --> 00:03:47,730
Kumbuka kwamba ili kwa sare ya yako
kazi lazima echo au kioo ili

62
00:03:47,730 --> 00:03:48,980
katika kazi yako kuanzishwa.

63
00:03:48,980 --> 00:03:51,290

64
00:03:51,290 --> 00:03:55,160
>> Sasa kwa kuwa wewe kuanzishwa bodi na
kwamba umefanya inayotolewa, ni wakati wa basi

65
00:03:55,160 --> 00:03:58,500
user hariri na kufanya hatua yao.

66
00:03:58,500 --> 00:04:03,840
Hivyo katika kazi Fifteen.c,
mpango inachukua pembejeo kutoka kwa mtumiaji na

67
00:04:03,840 --> 00:04:07,690
kisha wito hoja kazi, kupita
idadi ya tile kwamba

68
00:04:07,690 --> 00:04:09,270
user anataka hoja.

69
00:04:09,270 --> 00:04:10,380
Sasa, kuwa makini.

70
00:04:10,380 --> 00:04:14,200
Hii ni idadi halisi ya tile
na siyo msimamo wake halisi.

71
00:04:14,200 --> 00:04:19,010
Kwa hiyo, itabidi kutafuta tile ya
nafasi ya kujua ambapo ni.

72
00:04:19,010 --> 00:04:23,440
>> Sasa, unapaswa kuruhusu tu user
kufanya hoja kama ni za kisheria.

73
00:04:23,440 --> 00:04:27,910
hoja ya kisheria ni tile yoyote ambayo ni
karibu na tile tupu.

74
00:04:27,910 --> 00:04:32,020
Hii ina maana, juu na chini, kwa
kushoto na kulia.

75
00:04:32,020 --> 00:04:34,680
Hivyo itabidi haja ya kujua ambapo
tile tupu ni kama vizuri.

76
00:04:34,680 --> 00:04:39,720
Sasa, kwa kila hoja wewe ni kwa ajili ya kutafuta
watumiaji tile, lakini pengine

77
00:04:39,720 --> 00:04:43,030
si bora kutafuta tile tupu
kila wakati kwa sababu wewe kufanya hivyo

78
00:04:43,030 --> 00:04:45,270
kila wakati
user anataka hoja.

79
00:04:45,270 --> 00:04:50,300
Hivyo, badala yake, ni bora kukumbuka ambapo
tile tupu ni kutumia baadhi

80
00:04:50,300 --> 00:04:52,650
vizuri jina lake vigezo.

81
00:04:52,650 --> 00:04:55,970
Hivyo mara moja kuruhusu user kufanya wao
hatua, wao ni vizuri juu yao

82
00:04:55,970 --> 00:04:59,700
njia ya kushinda mchezo wa kumi na tano.

83
00:04:59,700 --> 00:05:03,940
>> Kushinda mchezo wa kumi na tano, tiles
kuwa katika utaratibu maalum, na

84
00:05:03,940 --> 00:05:06,970
kazi alishinda hundi kama
mchezo ni alishinda.

85
00:05:06,970 --> 00:05:10,290
Kuirudisha kweli kama mchezo ni mshindi na
tiles ni katika mpangilio sahihi,

86
00:05:10,290 --> 00:05:12,210
na uongo vinginevyo.

87
00:05:12,210 --> 00:05:15,830
Hivyo kushinda mchezo wa kumi na tano, tiles
kuwa kuongeza ili, kwa

88
00:05:15,830 --> 00:05:19,230
tupu tile chini kona ya kulia.

89
00:05:19,230 --> 00:05:23,630
Hivyo ni jinsi gani kuangalia kama user
ina wakiongozwa bodi katika haki

90
00:05:23,630 --> 00:05:25,010
Mwelekeo?

91
00:05:25,010 --> 00:05:29,200
>> Naam, wewe utakuwa iterate juu ya bodi na
kuangalia maadili kuhakikisha kwamba

92
00:05:29,200 --> 00:05:30,550
wao uko katika mahali pa haki.

93
00:05:30,550 --> 00:05:33,910
Kwa kufanya hivyo, unaweza kutumia Furushi
kwa loops tu kama alivyofanya

94
00:05:33,910 --> 00:05:36,520
katika kuteka na katika init.

95
00:05:36,520 --> 00:05:40,430
Kuna michache ya njia ya kuangalia
na kuhalalisha kama bodi ni

96
00:05:40,430 --> 00:05:42,860
sahihi na kushinda
malezi, ingawa.

97
00:05:42,860 --> 00:05:47,330
Kama kwenda kutoka kushoto kwenda kulia, kuanzia
kutoka safu ya juu chini, kisha kila

98
00:05:47,330 --> 00:05:50,590
Idadi ya lazima kuwa kubwa kuliko
mmoja uliopita.

99
00:05:50,590 --> 00:05:54,530
Kuwa makini katika yale thamani wameweza
waliochaguliwa kwa ajili ya tile yako tupu ingawa.

100
00:05:54,530 --> 00:05:59,250
>> Au unaweza kutumia kukabiliana na kutofautiana kwa
kuhakikisha kuwa kila thamani ni katika mahali, kama

101
00:05:59,250 --> 00:06:03,660
wewe kuja na aina fulani ya
formula kuwakilisha hii.

102
00:06:03,660 --> 00:06:06,250
Hivyo kuwa na furaha majaribio
na math.

103
00:06:06,250 --> 00:06:10,930
Mara moja umefanya kuja na njia, kurudi
Kweli mara moja user ameshinda mchezo.

104
00:06:10,930 --> 00:06:15,950
Lakini kama thamani yoyote ni sahihi, kurudi
Uongo, user ina kuendelea kusonga

105
00:06:15,950 --> 00:06:18,440
kwa sababu wao si alishinda mchezo.

106
00:06:18,440 --> 00:06:23,030
Mara baada ya kutekeleza hii kuangalia, pamoja
na initialize, kuchora, na hoja,

107
00:06:23,030 --> 00:06:25,110
kumaliza ya mchezo wa kumi na tano.

108
00:06:25,110 --> 00:06:27,620
Hongera na kuwa na furaha kucheza.

109
00:06:27,620 --> 00:06:30,600
Jina langu ni Zamyla na hii ni CS50.

110
00:06:30,600 --> 00:06:37,632
