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

2
00:00:00,470 --> 00:00:02,640
>> DAVID J. Malan: Ejja jimplimentaw
programm li jieħu vantaġġ mill-

3
00:00:02,640 --> 00:00:06,280
Librerija CS50, bl-użu funzjoni msejħa
jiksbu int, li l-iskop fil-ħajja huwa li

4
00:00:06,280 --> 00:00:09,960
tagħmel dan, li jkollna int,
jew integer, mill-utent.

5
00:00:09,960 --> 00:00:14,350
Well, biex jużaw din il-funzjoni aħna l-ewwel
jeħtieġ li jinkludu l-librerija CS50

6
00:00:14,350 --> 00:00:17,480
fajl tal-header, li nistgħu nagħmlu ma '
il sharp jinkludu dikjarazzjoni.

7
00:00:17,480 --> 00:00:22,470
>> Ejja jmiss, kif aħna spiss, jinkludu
io.h standard hekk li għandna aċċess

8
00:00:22,470 --> 00:00:24,410
għal funzjoni bħal printf.

9
00:00:24,410 --> 00:00:29,450
Ejja issa jiddikjara prinċipali, hija stess, ma int
null prinċipali, Brace kaboċċi miftuħa, u

10
00:00:29,450 --> 00:00:31,780
Brace kaboċċi preemptively qrib.

11
00:00:31,780 --> 00:00:35,740
U ejja issa tipproċedi biex fil-pront l-utent
għal żewġ interi, u sejħa ejja

12
00:00:35,740 --> 00:00:38,210
minnhom, għall-fini ta '
diskussjoni, x u y.

13
00:00:38,210 --> 00:00:42,140
U ejja finalment żid dawn iż-żewġ valuri,
X u Y, flimkien sabiex

14
00:00:42,140 --> 00:00:45,060
timplimenta l-aktar sempliċi ħafna
ta 'kalkolaturi.

15
00:00:45,060 --> 00:00:50,080
>> printf, jekk jogħġbok agħti me int.

16
00:00:50,080 --> 00:00:52,780
U issa għandna bżonn li fil-fatt tikseb
li int mill-utent.

17
00:00:52,780 --> 00:00:57,670
Biex tagħmel dan, jien ser tiddikjara
varjabbli imsejħa x, u b'hekk kienu allokati

18
00:00:57,670 --> 00:01:01,390
xi memorja fil-kompjuter
għal dan il-varjabbli, x.

19
00:01:01,390 --> 00:01:05,740
U issa let me tassenja, permezz tal-
operatur assenjazzjoni, il-valur tar-ritorn,

20
00:01:05,740 --> 00:01:07,800
biex ngħidu hekk, ta get int.

21
00:01:07,800 --> 00:01:11,440
Fi kliem ieħor, fuq il-lemin
ta 'din l-espressjoni, ejja sejħa jiksbu

22
00:01:11,440 --> 00:01:16,630
int, li huwa funzjoni dikjarata
CS50.h, u jippermettu nikseb int tagħmel il-

23
00:01:16,630 --> 00:01:20,490
irfigħ ta 'jkollna int b'xi mod
mill-utent, jirritornaha,

24
00:01:20,490 --> 00:01:24,210
biex ngħidu hekk, u mbagħad maħżuna minn
il-lemin ta 'din l-espressjoni

25
00:01:24,210 --> 00:01:26,680
fil-naħa tax-xellug
ta 'din l-espressjoni.

26
00:01:26,680 --> 00:01:29,570
>> Ejja jmiss jagħmlu l-istess ħaġa, din
time jkollna valur għal

27
00:01:29,570 --> 00:01:31,440
varjabbli imsejħa y.

28
00:01:31,440 --> 00:01:36,760
printf, jekk jogħġbok agħti me int ieħor.

29
00:01:36,760 --> 00:01:40,220
int y, u b'hekk tiddikjara ġdida
varjabbli, dan iż-żmien imsejħa

30
00:01:40,220 --> 00:01:43,660
y, ugwali tikseb int.

31
00:01:43,660 --> 00:01:47,010
Fi kliem ieħor, I jista 'sejħa get int
ħinijiet multipli, u kull darba huwa

32
00:01:47,010 --> 00:01:50,690
ser jirritorna kwalunkwe numru sħiħ
l-utent fil-fatt ittajpjat.

33
00:01:50,690 --> 00:01:53,920
>> Fl-aħħarnett, ejja żid xuy flimkien.

34
00:01:53,920 --> 00:02:02,620
printf, din is-somma ta '% d% u d, hekk
kliem ieħor, jien ser plagg fil-

35
00:02:02,620 --> 00:02:06,400
valuri ta 'xuy għal dawk
Valuri placeholder.

36
00:02:06,400 --> 00:02:10,720
% D huwa, ukoll,% d.

37
00:02:10,720 --> 00:02:13,710
Fi kliem ieħor, jekk I żid int wieħed
li int ieħor, jien ser

38
00:02:13,710 --> 00:02:14,810
tikseb terz int.

39
00:02:14,810 --> 00:02:18,750
Għalhekk, jien ser tuża t-tielet
post detentur għal int.

40
00:02:18,750 --> 00:02:22,540
>> Perjodu, backslash n, biss li jitqiegħed ġdida
linja fuq l-iskrin sabiex jimxu l-

41
00:02:22,540 --> 00:02:25,160
cursor isfel pulit, kwotazzjoni qrib.

42
00:02:25,160 --> 00:02:28,490
>> Issa, printf, f'dan il-każ, huwa għaddej
ikollok tieħu xi addizzjonali

43
00:02:28,490 --> 00:02:30,200
argumenti, tlieta, fil-fatt.

44
00:02:30,200 --> 00:02:33,580
Minħabba f'dan l-ewwel argument, stajt
speċifikati tliet detenturi post.

45
00:02:33,580 --> 00:02:36,470
Hekk jien ser tissepara dawn
argumenti, bħal dejjem, ma virgoli.

46
00:02:36,470 --> 00:02:40,200
Din l-ewwel argument se tkun
x, it-tieni argument li qed jiġri

47
00:02:40,200 --> 00:02:43,950
li tkun y, u t-tielet argument bħal
se tkun, ukoll, biss

48
00:02:43,950 --> 00:02:46,910
espressjoni aritmetika, x plus y.

49
00:02:46,910 --> 00:02:51,730
Jien ser tagħlaq lista argument tiegħi ma
a parentesi, virgola b'punt, Save tiegħi

50
00:02:51,730 --> 00:02:54,140
fajl, u issa jikkompilaw dan il-programm.

51
00:02:54,140 --> 00:02:56,730
>> Kun aġent li jżid Ikteb.

52
00:02:56,730 --> 00:02:58,300
Jien lura fil Teptip fil-pront tiegħi.

53
00:02:58,300 --> 00:03:02,040
Ejja issa run - dot
mmejla aġent li jżid Ikteb.

54
00:03:02,040 --> 00:03:03,250
Jekk jogħġbok agħtini l-int.

55
00:03:03,250 --> 00:03:04,820
Nibdew bl 1.

56
00:03:04,820 --> 00:03:06,160
Jekk jogħġbok agħtini int ieħor.

57
00:03:06,160 --> 00:03:07,460
Ejja jmorru ma 2.

58
00:03:07,460 --> 00:03:11,060
U wieħed jittama, is-somma ta '1 u 2 huwa 3.

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