1
00:00:00,000 --> 00:00:00,366

2
00:00:00,366 --> 00:00:01,830
>> SPIKA: Tutaweza kuiita kamba.

3
00:00:01,830 --> 00:00:03,510
Ni tu mlolongo wa wahusika.

4
00:00:03,510 --> 00:00:05,790
Hakika, ni tu
safu ya wahusika.

5
00:00:05,790 --> 00:00:09,730
Na hata kama sisi kupata kamba kutoka
user katika njia ya kawaida na CS50 ya

6
00:00:09,730 --> 00:00:13,550
GetString, tunaweza kisha kuendelea na
iterate juu ya chars katika kamba kwamba

7
00:00:13,550 --> 00:00:17,110
moja kwa wakati mmoja kama kwamba ingawa
kamba ni kweli safu.

8
00:00:17,110 --> 00:00:18,660
Hebu jaribu hii katika kanuni.

9
00:00:18,660 --> 00:00:21,470
>> Ni pamoja na cs50.h.

10
00:00:21,470 --> 00:00:24,440
Ni pamoja na stdio.h.

11
00:00:24,440 --> 00:00:27,960
Na hebu pia ni pamoja na string.h
hivyo kwamba tuna kupata

12
00:00:27,960 --> 00:00:29,500
kwa StringLen kazi.

13
00:00:29,500 --> 00:00:33,220
Hebu sasa kutangaza kuu
kama int kuu ni batili.

14
00:00:33,220 --> 00:00:36,740
Na hebu sasa kuendelea na kupata
kamba kutoka kwa mtumiaji.

15
00:00:36,740 --> 00:00:39,480
Printf pembejeo.

16
00:00:39,480 --> 00:00:45,180
Hebu sasa kutangaza kamba kuiita
s, na kuwaita rafiki yetu GetString.

17
00:00:45,180 --> 00:00:49,570
>> Hebu sasa kuendelea na kuangalia, je, user
kweli nipe kamba kwa sababu

18
00:00:49,570 --> 00:00:53,370
ni zamu nje kwa GetString ya mwenyewe
nyaraka, GetString inaweza juu ya

19
00:00:53,370 --> 00:00:56,830
tukio kurudi NULL, mwangalizi maalum
thamani kwamba kimsingi

20
00:00:56,830 --> 00:00:59,630
inaonyesha kwamba mtumiaji hakuwa
kushirikiana na kwa namna fulani alifanya

21
00:00:59,630 --> 00:01:01,150
si kutoa kamba.

22
00:01:01,150 --> 00:01:03,190
Hivyo hebu angalia kwa kuwa
na hali hiyo.

23
00:01:03,190 --> 00:01:09,300
>> IF s haina NULL sawa, basi tunaweza
kudhani kwamba s ni kweli kamba,

24
00:01:09,300 --> 00:01:14,580
safu ya wahusika, na kuendelea na
iterate juu ya wahusika hao.

25
00:01:14,580 --> 00:01:22,240
YA int i anapata 0, hebu pia kutangaza n
kama sawa na kamba urefu wa s hivyo

26
00:01:22,240 --> 00:01:27,900
muda mrefu kama i ni chini ya n, na kila
iteration, hebu nyongeza i.

27
00:01:27,900 --> 00:01:35,200
Ndani ya kitanzi hii basi, hebu piga printf
ya% c backslash n na kisha kuziba

28
00:01:35,200 --> 00:01:41,140
ndani ya thamani hii s bracket i na hivyo
uchapishaji tabia ya moja kwa wakati mmoja kila

29
00:01:41,140 --> 00:01:42,420
ya magari katika s.

30
00:01:42,420 --> 00:01:45,210
>> Hebu sasa kukusanya na
kuendesha mpango huu.

31
00:01:45,210 --> 00:01:47,140
Kufanya kamba.

32
00:01:47,140 --> 00:01:52,500
. / String pembejeo yangu itakuwa "hello."
Na huko sisi kuwa nayo.

33
00:01:52,500 --> 00:01:55,410
H-E-L-L-O, kila char juu ya line yake mwenyewe.

34
00:01:55,410 --> 00:01:56,727
