1
00:00:00,000 --> 00:00:00,470

2
00:00:00,470 --> 00:00:02,640
>> DAVID J. Malan: Hebu kutekeleza
mpango huo inachukua faida ya

3
00:00:02,640 --> 00:00:06,280
CS50 maktaba, kwa kutumia kazi kuitwa
kupata int, ambao lengo katika maisha ni kwa

4
00:00:06,280 --> 00:00:09,960
kufanya hivyo tu, kwa kupata int,
au integer, kutoka kwa mtumiaji.

5
00:00:09,960 --> 00:00:14,350
Naam, kwa kutumia kazi hii sisi kwanza
haja ni pamoja na CS50 maktaba

6
00:00:14,350 --> 00:00:17,480
header file, ambayo tunaweza kufanya na
mkali ni pamoja na taarifa.

7
00:00:17,480 --> 00:00:22,470
>> Hebu ijayo, kama sisi mara nyingi kufanya, ni pamoja na
kiwango io.h ili sisi kupata

8
00:00:22,470 --> 00:00:24,410
kufanya kazi kama printf.

9
00:00:24,410 --> 00:00:29,450
Hebu sasa kutangaza kuu, yenyewe, kwa int
utupu kuu, wazi curly brace, na

10
00:00:29,450 --> 00:00:31,780
preemptively karibu curly brace.

11
00:00:31,780 --> 00:00:35,740
Na hebu sasa kuendelea na kuchochea user
kwa integers mbili, na wito hebu

12
00:00:35,740 --> 00:00:38,210
yao, kwa ajili ya
majadiliano, x na y.

13
00:00:38,210 --> 00:00:42,140
Na hebu hatimaye kuongeza thamani hizo mbili,
x na y, pamoja ili

14
00:00:42,140 --> 00:00:45,060
kutekeleza rahisi sana
ya calculators.

15
00:00:45,060 --> 00:00:50,080
>> printf, tafadhali nipe int.

16
00:00:50,080 --> 00:00:52,780
Na sasa tunahitaji kweli kupata
kwamba int kutoka kwa mtumiaji.

17
00:00:52,780 --> 00:00:57,670
Kwa kufanya hivyo, mimi nina kwenda kutangaza
variable kuitwa x, na hivyo kugawa

18
00:00:57,670 --> 00:01:01,390
baadhi ya kumbukumbu katika kompyuta
kwa kutofautiana hii, x.

19
00:01:01,390 --> 00:01:05,740
Na sasa napenda kuwapa, kwa kutumia
kazi operator, thamani ya kurudi,

20
00:01:05,740 --> 00:01:07,800
hivyo kusema, ya kupata int.

21
00:01:07,800 --> 00:01:11,440
Kwa maneno mengine, upande wa kulia
ya msemo huu, hebu simu kupata

22
00:01:11,440 --> 00:01:16,630
int, ambayo ni kazi alitangaza katika
CS50.h, na kuruhusu kupata int kufanya

23
00:01:16,630 --> 00:01:20,490
nzito kuondoa ya kupata int kwa namna fulani
kutoka kwa mtumiaji, kurudi yake,

24
00:01:20,490 --> 00:01:24,210
hivyo kusema, na kisha hifadhi hiyo kutoka
upande wa kulia wa kujieleza hii

25
00:01:24,210 --> 00:01:26,680
ndani ya upande wa kushoto
ya msemo huu.

26
00:01:26,680 --> 00:01:29,570
>> Hebu ijayo kufanya kitu kimoja, hii
wakati kupata thamani kwa

27
00:01:29,570 --> 00:01:31,440
variable kuitwa y.

28
00:01:31,440 --> 00:01:36,760
printf, tafadhali nipe mwingine int.

29
00:01:36,760 --> 00:01:40,220
int y, hivyo kutangaza mpya
variable, wakati hii inayoitwa

30
00:01:40,220 --> 00:01:43,660
y, ni sawa na kupata int.

31
00:01:43,660 --> 00:01:47,010
Kwa maneno mengine, siwezi kuwaita kupata int
mara nyingi, na kila wakati ni

32
00:01:47,010 --> 00:01:50,690
kwenda na kurudi chochote integer
mtumiaji kweli typed.

33
00:01:50,690 --> 00:01:53,920
>> Hatimaye, hebu kuongeza x na y pamoja.

34
00:01:53,920 --> 00:02:02,620
printf, kiasi hiki ya% d na% d, hivyo katika
maneno mengine, mimi nina kwenda kuziba katika

35
00:02:02,620 --> 00:02:06,400
maadili ya x na y kwa wale
placeholder maadili.

36
00:02:06,400 --> 00:02:10,720
% D ni, vizuri,% d.

37
00:02:10,720 --> 00:02:13,710
Kwa maneno mengine, kama mimi kuongeza moja int
mwingine int, mimi nina kwenda

38
00:02:13,710 --> 00:02:14,810
kupata int tatu.

39
00:02:14,810 --> 00:02:18,750
Kwa hiyo, mimi naenda kutumia tatu
mahali mmiliki kwa int.

40
00:02:18,750 --> 00:02:22,540
>> Kipindi, backslash n, tu kuweka mpya
line juu ya screen ili hoja

41
00:02:22,540 --> 00:02:25,160
mshale chini vizuri, quote karibu.

42
00:02:25,160 --> 00:02:28,490
>> Sasa, printf, katika kesi hii, ni kwenda
kuwa na kuchukua baadhi ya ziada

43
00:02:28,490 --> 00:02:30,200
hoja, tatu, kwa kweli.

44
00:02:30,200 --> 00:02:33,580
Kwa sababu katika hoja ya kwanza, nimekuwa
fulani tatu wamiliki wa mahali.

45
00:02:33,580 --> 00:02:36,470
Hivyo nina kwenda kwa tofauti ya hizi
hoja, kama siku zote, na koma.

46
00:02:36,470 --> 00:02:40,200
kwanza hoja hiyo ni kwenda kuwa
x, pili hoja hiyo ni kwenda

47
00:02:40,200 --> 00:02:43,950
kuwa y, na wa tatu hoja hiyo
ni kwenda kuwa, vizuri,

48
00:02:43,950 --> 00:02:46,910
kujieleza hesabu, x pamoja na y.

49
00:02:46,910 --> 00:02:51,730
Mimi naenda kuifunga hoja orodha yangu na
mabano, semicolon, Ila wangu

50
00:02:51,730 --> 00:02:54,140
faili, na sasa kukusanya mpango huu.

51
00:02:54,140 --> 00:02:56,730
>> Kufanya fira kuingia.

52
00:02:56,730 --> 00:02:58,300
Mimi nina nyuma katika haraka yangu blinking.

53
00:02:58,300 --> 00:03:02,040
Hebu sasa kuendesha - dot
kufyeka fira kuingia.

54
00:03:02,040 --> 00:03:03,250
Tafadhali nipe int.

55
00:03:03,250 --> 00:03:04,820
Hebu kuanza na 1.

56
00:03:04,820 --> 00:03:06,160
Tafadhali nipe mwingine int.

57
00:03:06,160 --> 00:03:07,460
Hebu kwenda na 2.

58
00:03:07,460 --> 00:03:11,060
Na hopefully, jumla ya 1 na 2 ni 3.

59
00:03:11,060 --> 00:03:12,980
