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

2
00:00:00,285 --> 00:00:03,030
>> DAVID J. Malan: Ann kòmanse ekri
kèk kondisyon ki pi konplike.

3
00:00:03,030 --> 00:00:06,530
An patikilye, se pou yo ekri yon pwogram
ki envit itilizatè a pou yon nonb antye ki pè,

4
00:00:06,530 --> 00:00:09,460
di, ant 1 ak 10, ak Lè sa a,
fè yon ti jan nan analiz.

5
00:00:09,460 --> 00:00:14,530
Men, fwa sa a rapò si wi ou non ke
nimewo a se ti piti oubyen mwayen oswa gwo nan

6
00:00:14,530 --> 00:00:17,480
gwosè, desen sa yo Distenksyon
san patipri abitrèman.

7
00:00:17,480 --> 00:00:21,040
>> Pou fè sa, mwen pral fè konfyans sou Pran
Int, ki fonksyon soti nan CS50 nan

8
00:00:21,040 --> 00:00:22,860
bibliyotèk ki fè egzakteman sa.

9
00:00:22,860 --> 00:00:24,350
Apre sa, mwen ap tou ale nan
ogmante ekri ak lèt ​​detache f.

10
00:00:24,350 --> 00:00:28,530
Se konsa, mwen pral jwenn te kòmanse
pa ki gen ladan cs50.h kòm

11
00:00:28,530 --> 00:00:31,880
byen io.h. kòm estanda

12
00:00:31,880 --> 00:00:36,460
>> Apre sa, ale nan Lè sa a, deklare prensipal nan la
fason nòmal, Int anile prensipal yo, Curly louvri

13
00:00:36,460 --> 00:00:38,440
atèl, fèmen aparèy Curly.

14
00:00:38,440 --> 00:00:41,240
Apre sa, mwen ap Lè sa a, ale nan de motive-
itilizatè a pou yon nonb antye ki pè.

15
00:00:41,240 --> 00:00:48,340
Ekri an lèt detache f, tanpri, ban m 'yon
int ant 1 ak 10.

16
00:00:48,340 --> 00:00:52,640
>> Koulye a, kite a jwenn ki Int pa deklare yon
varyab yo rele, di, n ak plase

17
00:00:52,640 --> 00:00:55,520
li valè a retounen nan Pran Int.

18
00:00:55,520 --> 00:00:57,300
Se pou nou fè kounye a yon ti jan nan analiz.

19
00:00:57,300 --> 00:01:04,500
>> Si n pi gran pase oswa egal a 0 ak
n se mwens pase oswa egal a, di, 3,

20
00:01:04,500 --> 00:01:12,560
Lè sa a, nou pral ale pi devan epi ekri ak lèt ​​detache
soti ou pran yon ti Int.

21
00:01:12,560 --> 00:01:15,730
>> Lòt Bagay, si itilizatè a chwazi, di,
yon valè mwayen gwosè, se pou yo

22
00:01:15,730 --> 00:01:16,960
tcheke pou ki jan sa a.

23
00:01:16,960 --> 00:01:23,360
Lòt Bagay si n pi gran pase oswa egal a,
di, 4 ak n se mwens pase oswa egal a,

24
00:01:23,360 --> 00:01:31,850
di, 7, Lè sa a, mwen pral ekri an lèt detache
soti ou pran yon Int mwayen an.

25
00:01:31,850 --> 00:01:36,490
>> Finalman, mwen pral asime ke si
valè a se ant 8 ak 10 yo, yo

26
00:01:36,490 --> 00:01:37,550
pran yon gwo Int.

27
00:01:37,550 --> 00:01:44,140
Se konsa, eksprime sa yo panse ke, mwen pral tape, lòt moun si
n pi gran pase oswa egal a 8 ak n

28
00:01:44,140 --> 00:01:53,590
se mwens pase oswa egal a 10, ale pi devan
epi enprime ou pran yon gwo Int.

29
00:01:53,590 --> 00:01:55,720
>> Lòt Bagay, gen nan yon kondisyon katriyèm isit la.

30
00:01:55,720 --> 00:01:59,520
Si itilizatè a pa t 'kolabore ak olye
tape yon valè sa a, se mwens pase

31
00:01:59,520 --> 00:02:04,430
0 oswa pi plis pase 10, mwen vle
tou senpleman reprimann yo.

32
00:02:04,430 --> 00:02:12,490
Lòt Bagay enprime soti, ou pran
yon Int valab.

33
00:02:12,490 --> 00:02:13,950
>> Se pou yo sove dosye a.

34
00:02:13,950 --> 00:02:17,580
Sanble l 'ak fè ki pa chanje.

35
00:02:17,580 --> 00:02:21,650
Retounen nan èd memwa m 'yo, mwen pral kouri
l 'ak dot koupe ki pa chanje.

36
00:02:21,650 --> 00:02:23,320
Li kite yo eseye kèk valè.

37
00:02:23,320 --> 00:02:26,110
>> Premyèman, se pou yo gen kooperatif
ak kalite nan negatif 1.

38
00:02:26,110 --> 00:02:30,970
Erezman, sa ki te detekte avèk nou
branch final la nan ki kondisyon.

39
00:02:30,970 --> 00:02:36,530
Ann eseye ankò ak dot koupe
ki pa Peye-switch, fwa sa a bay li 1.

40
00:02:36,530 --> 00:02:37,900
Mwen menm, mwen pran yon ti Int.

41
00:02:37,900 --> 00:02:43,250
>> Se pou yo fè l 'ankò ak dot koupe
ki pa Peye-switch, fwa sa a davwa, di, 5.

42
00:02:43,250 --> 00:02:44,590
Epi sa a, yon Int mwayen an.

43
00:02:44,590 --> 00:02:48,200
Se pou nou kounye a ankò dot
koupe ki pa chanje.

44
00:02:48,200 --> 00:02:52,650
Apre sa, bay li yon valè de 10, ki
se vre yon gwo Int.

45
00:02:52,650 --> 00:02:55,310
>> Kounye a li nan vo anyen ki pwogram sa a
te kapab aplike nan

46
00:02:55,310 --> 00:02:56,840
nenpòt ki kantite fason.

47
00:02:56,840 --> 00:03:00,160
Premye a tout, li te konplètman
abitrè ke mwen te trase liy ki sa mwen

48
00:03:00,160 --> 00:03:03,290
te fè nan mitan piti, mwayèn,
ak gwo antye.

49
00:03:03,290 --> 00:03:05,230
Nou te kapab te trase moun ki
limit nenpòt kote.

50
00:03:05,230 --> 00:03:08,930
>> Men, plis enteresan, mwen pa t 'gen
eksprime sa yo panse tèt mwen ak tout moun sa yo

51
00:03:08,930 --> 00:03:13,440
pi gran pase oswa egal a oswa pi piti
pase oswa egal a siy.

52
00:03:13,440 --> 00:03:18,880
Mwen te kapab, pou egzanp, ekri ankò si
n pi gran pase oswa egal a 4 ak

53
00:03:18,880 --> 00:03:24,760
n se mwens pase oswa egal a 7, kòm olye pou
si n pi gran pase 3 ak n

54
00:03:24,760 --> 00:03:29,130
gen mwens pase 8, Lè sa a, enprime soti
ou te chwazi yon Int mwayen an.

55
00:03:29,130 --> 00:03:33,360
>> Apre yo tout, si D 'itilizatè a, pa
lanati nan Pran Int, se yon nonb antye ki pè, nou

56
00:03:33,360 --> 00:03:37,580
kapab swa tès si ke valè ki pi konsekan
pase 3 oswa pi gran pase oswa

57
00:03:37,580 --> 00:03:38,740
egal a 4.

58
00:03:38,740 --> 00:03:43,130
Apre sa, nou te ka tcheke tou si sa
valè mwens ke 8 oswa mwens

59
00:03:43,130 --> 00:03:44,590
pase oswa egal a 7.

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