00:00:00,000 --> 00:00:10,180
>> [Halisi kucheza]

2
00:00:10,180 --> 00:00:11,100
>> ZAMYLA CHAN: Hello, dunia.

3
00:00:11,100 --> 00:00:13,670
Hebu kufanya C yetu ya kwanza ya mpango.

4
00:00:13,670 --> 00:00:17,720
>> Kuandika mipango yetu, tutaweza kuwa
kufanya kazi katika appliance CS50.

5
00:00:17,720 --> 00:00:21,565
Ni mashine virtual kwamba anaendesha
kompyuta ndani ya kompyuta yako.

6
00:00:21,565 --> 00:00:23,240
>> Hii ina mengi ya faida.

7
00:00:23,240 --> 00:00:28,140
Kwa moja, ni tayari kuanzisha na mengi
ya zana na itabidi kwa CS50.

8
00:00:28,140 --> 00:00:32,560
Pia ina maana kwamba kama una Mac,
PC, Linux, kila mtu anatumia

9
00:00:32,560 --> 00:00:33,950
kitu kimoja.

10
00:00:33,950 --> 00:00:37,170
Kama si kupakuliwa
CS50 appliance bado, kwenda

11
00:00:37,170 --> 00:00:41,940
manual.cs50.net/appliance.

12
00:00:41,940 --> 00:00:45,280
>> Nina Appliance yangu hapa screen kamili,
lakini pia unaweza kuwa ni kama yaliyo

13
00:00:45,280 --> 00:00:47,800
dirisha, kama unataka.

14
00:00:47,800 --> 00:00:51,190
Mimi sana kuhamasisha kuanzisha dropbox
akaunti kwa ajili ya wote wa CS50 yako

15
00:00:51,190 --> 00:00:52,170
Bila shaka kazi.

16
00:00:52,170 --> 00:00:56,400
Njia hiyo, katika kesi kitu kinachotokea na
kompyuta yako au Appliance,

17
00:00:56,400 --> 00:00:58,440
una Backup katika wingu.

18
00:00:58,440 --> 00:01:00,600
>> Hebu kufungua terminal yetu ya kwanza.

19
00:01:00,600 --> 00:01:03,860
terminal ni interface kwamba sisi
unaweza kutumia navigate kote wetu

20
00:01:03,860 --> 00:01:06,825
kompyuta, kuandika, kukusanya,
kanuni na kukimbia.

21
00:01:06,825 --> 00:01:10,010
Tutaweza kweli kuandika zaidi ya
kanuni zetu katika gedit, ingawa.

22
00:01:10,010 --> 00:01:11,820
>> Basi hebu kuleta hii hadi sasa.

23
00:01:11,820 --> 00:01:14,940
Hivyo itabidi atulete kwa hati wasiookoka.

24
00:01:14,940 --> 00:01:17,330
Taarifa kwamba mimi kuanza kuandika yangu C kanuni -

25
00:01:17,330 --> 00:01:19,500
hakuna syntax mwangaza wowote.

26
00:01:19,500 --> 00:01:23,670
Syntax mwangaza inatusaidia kuibua na
kuchorea data aina, kazi, na

27
00:01:23,670 --> 00:01:25,080
vigezo tofauti.

28
00:01:25,080 --> 00:01:30,620
>> Basi hebu kuokoa mpango huu katika
folder, na kuiita hello.c.

29
00:01:30,620 --> 00:01:33,960
Njia hii, tutaweza kuwa syntax
kuonyesha kama sisi aina.

30
00:01:33,960 --> 00:01:42,660

31
00:01:42,660 --> 00:01:45,120
Tutaweza kuanza na ikiwa ni pamoja
mbili maktaba -

32
00:01:45,120 --> 00:01:52,290
pamoja cs50.h na ni pamoja na stdio.h.

33
00:01:52,290 --> 00:01:56,730
Njia hii, mpango wetu itakuwa na upatikanaji
na kazi ndani ya CS50

34
00:01:56,730 --> 00:01:58,840
Darasa la I / O maktaba.

35
00:01:58,840 --> 00:02:02,070
>> Kila mpango mahitaji ya kazi kuu,
hivyo hebu kuandika kwamba hapa -

36
00:02:02,070 --> 00:02:06,290
kuu (utupu) na braces mbili curly.

37
00:02:06,290 --> 00:02:09,139
Na sasa hapa ni wapi utasikia
kuandika mpango wako.

38
00:02:09,139 --> 00:02:15,395
>> Kwa ajili ya mpango wetu wa kwanza, tutaweza tu
mstari mmoja printf, hello, dunia!

39
00:02:15,395 --> 00:02:18,070

40
00:02:18,070 --> 00:02:22,090
Na mstari mpya wa kulia
hapa kwa ajili ya aesthetics.

41
00:02:22,090 --> 00:02:24,930
>> Mara baada ya mimi kuokoa, nataka kukimbia mpango wangu.

42
00:02:24,930 --> 00:02:27,200
Hivyo nina kwenda kufungua terminal yangu sasa.

43
00:02:27,200 --> 00:02:32,260
Mimi kuanza kwenda katika saraka ya nyumbani yangu, lakini
kupata hello.c, mimi haja ya kuwa katika

44
00:02:32,260 --> 00:02:34,720
saraka ya sawa au folder.

45
00:02:34,720 --> 00:02:38,800
Hivyo katika haki hii ya haraka hapa,
Mimi naenda aina cd -

46
00:02:38,800 --> 00:02:40,700
mabadiliko ya saraka -

47
00:02:40,700 --> 00:02:45,960
Dropbox/2013/walkthroughs.

48
00:02:45,960 --> 00:02:48,220
Na sasa niko katika folder yangu walkthroughs.

49
00:02:48,220 --> 00:02:49,820
>> Kusema mimi kusahau kile yangu
folders ni kuitwa.

50
00:02:49,820 --> 00:02:54,130
Basi mimi itabidi aina ls, ambayo itakuwa
kuorodhesha wote wa files katika

51
00:02:54,130 --> 00:02:55,860
saraka hii ya sasa.

52
00:02:55,860 --> 00:03:03,480
Hivyo kubadilisha directories chache
mara zaidi, mimi kupata hello.c.

53
00:03:03,480 --> 00:03:07,040
Na mchakato huu ni sawa na
punde kwa njia Finder juu ya Macs au

54
00:03:07,040 --> 00:03:08,540
Kompyuta yangu katika Windows.

55
00:03:08,540 --> 00:03:12,100
Kwa kweli, siwezi hata kufanya folders au
directories haki kutoka terminal

56
00:03:12,100 --> 00:03:16,240
na Directory kufanya
amri, mkdir.

57
00:03:16,240 --> 00:03:20,400
>> Kama unataka kuondoa faili, unaweza
kuondoa hiyo kutoka terminal na RN,

58
00:03:20,400 --> 00:03:24,390
ikifuatiwa na jina la faili
unataka kuondoa, na kuandika y kwa ndiyo

59
00:03:24,390 --> 00:03:28,420
wakati terminal akiwauliza
kuthibitisha kufutwa.

60
00:03:28,420 --> 00:03:29,970
>> Kuwa na uhakika wa kuchunguza wastaafu.

61
00:03:29,970 --> 00:03:32,800
Kuna tani ya keyboard shortcuts
kukusaidia nje.

62
00:03:32,800 --> 00:03:37,060
Pia, gedit kweli ina ndogo
terminal chini hapa ambapo

63
00:03:37,060 --> 00:03:40,746
unaweza kufanya mambo sawa sisi alifanya
katika terminal yetu kubwa.

64
00:03:40,746 --> 00:03:44,290
>> Kwa sasa, hebu kukusanya code wetu
kwa amri zifuatazo -

65
00:03:44,290 --> 00:03:46,430
kufanya hello.

66
00:03:46,430 --> 00:03:49,050
Sasa unapaswa kuona mstari na
rundo la amri.

67
00:03:49,050 --> 00:03:52,510
Kufanya kimsingi ni kanga kwamba tu
inapeleka orodha ya maagizo ya

68
00:03:52,510 --> 00:03:54,860
terminal pale unapoandika
katika neno moja.

69
00:03:54,860 --> 00:03:59,320
Katika kesi hiyo, ni mbio Clang,
mkusanyaji na seti ya maelekezo -

70
00:03:59,320 --> 00:04:00,030
bendera -

71
00:04:00,030 --> 00:04:03,310
juu ya jinsi ya kukusanya mpango.

72
00:04:03,310 --> 00:04:08,460
>> Sasa kwa kuwa tumekuwa compiled hello.c, kama sisi
ls, tunapaswa kuona faili la kutekelezwa

73
00:04:08,460 --> 00:04:11,720
kuitwa hodi katika orodha yetu.

74
00:04:11,720 --> 00:04:18,430
Sisi kukimbia kwa kuandika /. Hello, na
kuna mpango wetu pato.

75
00:04:18,430 --> 00:04:19,380
>> Hello, dunia.

76
00:04:19,380 --> 00:04:21,670
Jina langu ni Zamyla, na hii ni CS50.

77
00:04:21,670 --> 00:04:28,714
