1
00:00:00,000 --> 00:00:00,330

2
00:00:00,330 --> 00:00:03,230
>> SPIKA: Hadi sasa, katika programu tumekuwa
imeandikwa, tumekuwa alitangaza kuu kama

3
00:00:03,230 --> 00:00:04,940
int utupu kuu.

4
00:00:04,940 --> 00:00:07,600
Na muda wote huu, kwamba utupu ina
tu kuwa kubainisha kwamba

5
00:00:07,600 --> 00:00:10,870
haina mpango wa kuchukua yoyote
hoja mstari amri.

6
00:00:10,870 --> 00:00:14,180
Kwa maneno mengine, wakati mtumiaji anaendesha
mpango, anaweza kutoa amri

7
00:00:14,180 --> 00:00:18,130
line hoja kwa kuandika ziada
maneno au misemo baada ya mpango wa

8
00:00:18,130 --> 00:00:19,420
jina katika haraka.

9
00:00:19,420 --> 00:00:22,980
>> Naam, ikiwa unataka mpango wako kwa
kuchukua hoja mstari amri moja au

10
00:00:22,980 --> 00:00:26,960
maneno zaidi hiyo, tunahitaji kuchukua nafasi ya
utupu na michache ya hoja.

11
00:00:26,960 --> 00:00:28,630
Basi hebu kufanya hivyo.

12
00:00:28,630 --> 00:00:32,170
Ni pamoja na CS50.h.

13
00:00:32,170 --> 00:00:35,760
Pamoja na kiwango io.h.

14
00:00:35,760 --> 00:00:40,830
Int, kuu, na sasa badala ya batili,
Mimi nina kwenda bayana int aitwaye

15
00:00:40,830 --> 00:00:45,800
argc, na safu ya
masharti aitwaye argv.

16
00:00:45,800 --> 00:00:48,240
>> Sasa, argc na argv ni
tu mikataba.

17
00:00:48,240 --> 00:00:50,530
Tunaweza wameweza simu hoja hizi
wengi chochote tunataka.

18
00:00:50,530 --> 00:00:54,050
Lakini jambo muhimu ni kwamba argc ni
int, kwa sababu kwa ufafanuzi, ni

19
00:00:54,050 --> 00:00:57,810
kwenda vyenye hoja makosa,
idadi ya maneno katika jumla kwamba

20
00:00:57,810 --> 00:00:59,830
mtumiaji typed katika yake haraka.

21
00:00:59,830 --> 00:01:04,310
>> Argv, wakati huo huo, hoja vector, ni
kwenda kweli kuwa safu ya kuhifadhi

22
00:01:04,310 --> 00:01:08,460
maneno yote kwamba mtumiaji ina
typed katika yake haraka.

23
00:01:08,460 --> 00:01:10,920
Hebu kuendelea kufanya kitu sasa
kwa moja au zaidi ya haya

24
00:01:10,920 --> 00:01:12,090
hoja mstari amri.

25
00:01:12,090 --> 00:01:16,440
Hasa, hebu kwenda mbele na magazeti
chochote neno aina ya mtumiaji

26
00:01:16,440 --> 00:01:20,380
baada ya jina mpango wa
katika haraka.

27
00:01:20,380 --> 00:01:26,940
>> Open bracket, kufungwa bracket, magazeti
f, asilimia s, backslash n, comma.

28
00:01:26,940 --> 00:01:30,930
Na sasa mimi haja ya kuwaambia magazeti f nini
thamani kuziba ndani ya kwamba placeholder.

29
00:01:30,930 --> 00:01:35,030
Nataka neno la kwanza kwamba mtumiaji ina
typed baada ya jina mpango huo.

30
00:01:35,030 --> 00:01:39,550
Na hivyo mimi nina kwenda kwa kutaja
argv bracket 1, imefungwa

31
00:01:39,550 --> 00:01:41,250
mabano, semicolon.

32
00:01:41,250 --> 00:01:43,710
>> Sasa, kwa nini bracket 1 na si bracket 0?

33
00:01:43,710 --> 00:01:47,410
Naam, ni zamu nje, moja kwa moja kuhifadhiwa
katika argv 0 ni kwenda kuwa

34
00:01:47,410 --> 00:01:49,040
mpango wa jina halisi.

35
00:01:49,040 --> 00:01:52,600
Hivyo neno la kwanza kwamba aina user
baada ya jina mpango wa ni, kwa

36
00:01:52,600 --> 00:01:55,410
mkataba huo, kwenda kuwa
kuhifadhiwa katika argv 1.

37
00:01:55,410 --> 00:01:58,800
>> Hebu sasa kukusanya na
kuendesha mpango huu.

38
00:01:58,800 --> 00:02:08,080
Kufanya argv 0 dot slash argv 0, na
sasa neno kama hello, kuingia.

39
00:02:08,080 --> 00:02:09,330
Na huko sisi kuwa nayo, hello.

40
00:02:09,330 --> 00:02:11,332
