00:00:06,972 --> 00:00:08,870
[Powered by Google Translate] Christopher BARTHOLOMEW: Karibu tena.

2
00:00:08,870 --> 00:00:12,730
Katika video mwingine, tulijadili data Char aina katika C ambayo

3
00:00:12,730 --> 00:00:16,570
inaweza kutumika kwa kushikilia herufi, nambari na herufi maalum

4
00:00:16,570 --> 00:00:19,420
vile kama swali au alama Moderators.

5
00:00:19,420 --> 00:00:22,660
Sisi tunajua kwamba mtu ana thamani Char ASCII, ambayo

6
00:00:22,660 --> 00:00:25,280
ni uwakilishi integer wa tabia.

7
00:00:25,280 --> 00:00:29,690
Kwa mfano, mji mkuu wa barua ya A thamani ASCII ni 65.

8
00:00:29,690 --> 00:00:34,570
Lakini katika C, je, sisi kutumia kwa ajili ya maneno halisi au sentensi vile

9
00:00:34,570 --> 00:00:37,940
kama programu, au "C ni mzuri?"

10
00:00:37,940 --> 00:00:39,550
Jibu ni string -

11
00:00:39,550 --> 00:00:42,340
lakini kwa kuwa maalumu zaidi, ni string tabia.

12
00:00:44,850 --> 00:00:48,250
string tabia, au kamba, ni mlolongo wa moja

13
00:00:48,250 --> 00:00:50,210
Byte chars kwamba ni kuhifadhiwa sambamba

14
00:00:50,210 --> 00:00:52,000
kila mmoja katika kumbukumbu.

15
00:00:52,000 --> 00:00:55,000
Na mwishoni mwa yoyote string tabia katika C

16
00:00:55,000 --> 00:00:57,190
lugha, kuna mmoja ziada Byte kwamba ni

17
00:00:57,190 --> 00:00:59,410
zilizotengwa kwa ajili ya tabia maalum -

18
00:00:59,410 --> 00:01:03,565
backslash 0, ambayo ni null kuondoa tabia.

19
00:01:03,565 --> 00:01:07,290
null kuondoa tabia ni Char 1 Byte ambaye bits

20
00:01:07,290 --> 00:01:10,900
wote ni 0 na ni kutumika kuashiria mwisho

21
00:01:10,900 --> 00:01:12,860
ya kamba katika kumbukumbu.

22
00:01:12,860 --> 00:01:16,370
Hii ina maana kama unakusudia initialize string yako kama

23
00:01:16,370 --> 00:01:22,610
sentensi ya "C ni kujifurahisha," au tu neno "kujifurahisha," katika

24
00:01:22,610 --> 00:01:26,100
mwisho siku zote kutakuwa null kuondoa tabia

25
00:01:26,100 --> 00:01:29,420
kuonyesha kwamba string ina kumalizika.

26
00:01:29,420 --> 00:01:32,200
Kutumia kamba katika mpango wako, inashauriwa

27
00:01:32,200 --> 00:01:34,440
kwamba wewe initialize variable yako kama hii -

28
00:01:38,050 --> 00:01:46,720
chati nyota S sawa quote wazi, kamba yako, karibu

29
00:01:46,720 --> 00:01:50,220
quote, semicolon.

30
00:01:50,220 --> 00:01:54,880
Katika ufafanuzi huu variable, variable S pointi ya kwanza

31
00:01:54,880 --> 00:02:01,040
tabia katika kamba yetu, ambayo ni C. Unaweza kuona, kwa sababu sisi sasa

32
00:02:01,040 --> 00:02:04,500
kujua string nzima ni kuhifadhiwa sequentially katika kumbukumbu,

33
00:02:04,500 --> 00:02:08,009
tunaweza retrieve string na hakuna matatizo kama sisi pia

34
00:02:08,009 --> 00:02:09,919
kujua ambapo ni mwisho, pia -

35
00:02:09,919 --> 00:02:12,060
null kuondoa tabia.

36
00:02:12,060 --> 00:02:13,350
Hivyo kuwa na furaha.

37
00:02:13,350 --> 00:02:16,750
Mimi nina Christopher Bartholomayo, hii ni cs50.
