1
00:00:00,000 --> 00:00:00,285

2
00:00:00,285 --> 00:00:03,030
>> DAVID J. Malan: Ejja tibda bil-miktub
xi kundizzjonijiet aktar kumplessi.

3
00:00:03,030 --> 00:00:06,530
B'mod partikolari, ejja jikteb programm
li tinkoraġġixxi l-utent għal integer,

4
00:00:06,530 --> 00:00:09,460
jiġifieri bejn 1 u 10, u mbagħad
ma daqsxejn ta 'analiżi.

5
00:00:09,460 --> 00:00:14,530
Iżda rapportar dan iż-żmien jekk dik
in-numru huwa żgħir jew medju jew kbar fi

6
00:00:14,530 --> 00:00:17,480
daqs, tpinġija dawk distinzjonijiet
pjuttost arbitrarju.

7
00:00:17,480 --> 00:00:21,040
>> Biex tagħmel dan, jien ser jiddependu fuq get
int, dik il-funzjoni mill-CS50

8
00:00:21,040 --> 00:00:22,860
librerija li ma eżattament dan.

9
00:00:22,860 --> 00:00:24,350
U jien ukoll ser
leverage print f.

10
00:00:24,350 --> 00:00:28,530
Hekk jien ser tibda
billi jinkludi cs50.h bħala

11
00:00:28,530 --> 00:00:31,880
ukoll io.h. bħala standard

12
00:00:31,880 --> 00:00:36,460
>> U ser mbagħad tiddikjara prinċipali fil-
mod tas-soltu, null prinċipali int, kaboċċi miftuħa

13
00:00:36,460 --> 00:00:38,440
Brace, Brace kaboċċi qrib.

14
00:00:38,440 --> 00:00:41,240
U jien imbagħad ser pront
l-utent għal integer.

15
00:00:41,240 --> 00:00:48,340
Stampa f, jekk jogħġbok agħti me
int bejn 1 u 10.

16
00:00:48,340 --> 00:00:52,640
>> Issa ejja nikseb li int billi jiddikjara a
varjabbli imsejħa, jiġifieri, n u assenjazzjoni

17
00:00:52,640 --> 00:00:55,520
dan il-valur tar-ritorn tal get int.

18
00:00:55,520 --> 00:00:57,300
Ejja issa jagħmlu daqsxejn ta 'analiżi.

19
00:00:57,300 --> 00:01:04,500
>> Jekk n hija akbar minn jew ugwali għal 0 u
n hija inqas minn jew ugwali għal, per eżempju, 3,

20
00:01:04,500 --> 00:01:12,560
allura aħna qed tmur biex imorru quddiem u print
out inti qabad int żgħir.

21
00:01:12,560 --> 00:01:15,730
>> Else, jekk l-utent fisien, ngħidu aħna,
Valur ta 'daqs medju, ejja

22
00:01:15,730 --> 00:01:16,960
jikkontrolla għal dak kif ġej.

23
00:01:16,960 --> 00:01:23,360
Inkella jekk n hija akbar minn jew ugwali għal,
jiġifieri, 4 u n hija inqas minn jew ugwali għal,

24
00:01:23,360 --> 00:01:31,850
jiġifieri, 7, allura jien ser jistampaw
out inti qabad int medju.

25
00:01:31,850 --> 00:01:36,490
>> Fl-aħħarnett, jien ser jassumi li jekk
il-valur huwa bejn 8 u 10, huma

26
00:01:36,490 --> 00:01:37,550
qabad int kbir.

27
00:01:37,550 --> 00:01:44,140
Allura biex jesprimu dak, jien ser tip, inkella jekk
n hija akbar minn jew ugwali għal 8 u n

28
00:01:44,140 --> 00:01:53,590
hija inqas minn jew ugwali għal 10, imorru quddiem
u tistampa inti qabad int kbir.

29
00:01:53,590 --> 00:01:55,720
>> Else, hemm raba kundizzjoni hawn.

30
00:01:55,720 --> 00:01:59,520
Jekk l-utent ma kkooperax u minflok
ittajpjat valur li l-anqas minn

31
00:01:59,520 --> 00:02:04,430
0 jew akbar minn 10, nixtieq
li sempliċiment ċanfira lilhom.

32
00:02:04,430 --> 00:02:12,490
Else jistampa, inti qabad
ta int invalidu.

33
00:02:12,490 --> 00:02:13,950
>> Ejja tiffranka l-fajl.

34
00:02:13,950 --> 00:02:17,580
Josservawha ma tagħmel non-swiċċ.

35
00:02:17,580 --> 00:02:21,650
Lura fil-pront tiegħi, jien ser jimxu
ma dot mmejla mhux switch.

36
00:02:21,650 --> 00:02:23,320
U ejja tipprova valuri ftit.

37
00:02:23,320 --> 00:02:26,110
>> L-ewwel, ejja tkun mhux kooperattiva
u tip negattiv 1.

38
00:02:26,110 --> 00:02:30,970
Fortunatament, li ġie rreġistrat minn tagħna
fergħa finali f'dik il-kondizzjoni.

39
00:02:30,970 --> 00:02:36,530
Ejja erġa 'pprova ma' dot slash
mhux swiċċ, dan iż-żmien tagħtiha 1.

40
00:02:36,530 --> 00:02:37,900
I tassew qabad int żgħir.

41
00:02:37,900 --> 00:02:43,250
>> Ejja nagħmlu dan mill-ġdid ma 'dot slash
mhux swiċċ, dan iż-żmien picking, ngħidu aħna, 5.

42
00:02:43,250 --> 00:02:44,590
U li l-int medju.

43
00:02:44,590 --> 00:02:48,200
Ejja issa do darb'oħra dot
mmejla mhux switch.

44
00:02:48,200 --> 00:02:52,650
U jagħtu valur ta '10, li
huwa tabilħaqq int kbir.

45
00:02:52,650 --> 00:02:55,310
>> Issa huwa min jinnota li dan il-programm
setgħu ġew implimentati

46
00:02:55,310 --> 00:02:56,840
kwalunkwe numru ta 'modi.

47
00:02:56,840 --> 00:03:00,160
L-ewwelnett, kien kompletament
arbitrarja li I ġibdet l-linji li I

48
00:03:00,160 --> 00:03:03,290
għamlet fost żgħar, medji,
u ints kbar.

49
00:03:03,290 --> 00:03:05,230
Nistgħu fasslu dawk
konfini kullimkien.

50
00:03:05,230 --> 00:03:08,930
>> Iżda aktar interessanti, I ma kellhomx
biex jesprimu myself ma 'dawn kollha

51
00:03:08,930 --> 00:03:13,440
ikbar minn jew daqs jew inqas
minn jew ugwali għal sinjali.

52
00:03:13,440 --> 00:03:18,880
I setgħet, per eżempju, miktuba mill-ġdid jekk
n hija akbar minn jew ugwali għal 4 u

53
00:03:18,880 --> 00:03:24,760
n hija inqas minn jew ugwali għal 7, kif minflok
jekk n hija akbar minn 3 u n

54
00:03:24,760 --> 00:03:29,130
huwa inqas minn 8, allura jistampa
inti qabad int medju.

55
00:03:29,130 --> 00:03:33,360
>> Wara kollox, jekk input tal-utent, mill-
natura tal get int, huwa integer, aħna

56
00:03:33,360 --> 00:03:37,580
tista 'jew test jekk dak il-valur ikun akbar
minn 3 jew ikbar minn jew

57
00:03:37,580 --> 00:03:38,740
ugwali għal 4.

58
00:03:38,740 --> 00:03:43,130
U nistgħu wkoll tivverifika jekk dan
valur inqas minn 8 jew inqas

59
00:03:43,130 --> 00:03:44,590
minn jew daqs 7.

60
00:03:44,590 --> 00:03:45,860
