00:00:02,670 --> 00:00:11,834

3
00:00:11,834 --> 00:00:13,365
>> Oratè 1: Hi, tout moun.

4
00:00:13,365 --> 00:00:14,365
Byenveni tounen nan seksyon.

5
00:00:14,365 --> 00:00:15,700

6
00:00:15,700 --> 00:00:18,700
Lovely jou out-- ki se poukisa, mwen se
asire w, te gen sèlman kat nan ou isit la

7
00:00:18,700 --> 00:00:21,180
epi yo pa pake abityèl nou an.

8
00:00:21,180 --> 00:00:22,670
Mwen te malad nan fen semèn sa.

9
00:00:22,670 --> 00:00:24,294
Se konsa, mwen pa gen Starburst pou ou guys.

10
00:00:24,294 --> 00:00:26,400
Apre sa, mwen ka kòmanse touse
fò anpil nan tout sa a.

11
00:00:26,400 --> 00:00:27,790
Se konsa, jis pote avè m '.

12
00:00:27,790 --> 00:00:30,624
Mwen pral reyèlman eseye
epi pou yo jwenn nan sa a premye,

13
00:00:30,624 --> 00:00:32,290
menm si, mwen anvan m 'gen yon atak touse.

14
00:00:32,290 --> 00:00:33,410

15
00:00:33,410 --> 00:00:37,390
Men, jis dwe fasil sou m 'yon
ti kras bit-- ki nan tout mwen mande.

16
00:00:37,390 --> 00:00:39,370

17
00:00:39,370 --> 00:00:44,289
>> Se konsa, ajanda nou an pou today-- jis yon
reminder-- egzamen ou an se semèn pwochèn.

18
00:00:44,289 --> 00:00:46,830
Mwen te di nou sa a semèn pase a se konsa li
pa ta trape ou nan gad.

19
00:00:46,830 --> 00:00:47,954
Se konsa, mwen fè ou sonje ankò.

20
00:00:47,954 --> 00:00:49,180
Semèn pwochen an egzamen ou yo.

21
00:00:49,180 --> 00:00:52,730
Pou sa fini, semèn pwochen an
seksyon pral pi plis

22
00:00:52,730 --> 00:00:55,180
of-- m ap eseye ak travay nan kèk revizyon.

23
00:00:55,180 --> 00:00:58,130
Se konsa, si ou nèg te kapab
ede m 'soti pa voye m'

24
00:00:58,130 --> 00:01:00,990
bagay sa yo ke w ap konfòtab
ak, ke w ap enkyete w sou,

25
00:01:00,990 --> 00:01:03,530
sijè ki ou ta renmen pou
m 'yo kouvri, ki ta dwe gwo.

26
00:01:03,530 --> 00:01:05,740
Se konsa, mwen ka eseye ak travay yo
nan seksyon nou an semèn pwochèn

27
00:01:05,740 --> 00:01:11,540
oswa voye ba ou materyèl siplemantè oswa preparasyon
ke ou pa ta ka jwenn yon lòt kote.

28
00:01:11,540 --> 00:01:12,150
>> Yeah!

29
00:01:12,150 --> 00:01:13,520
Plis moun ap vini!

30
00:01:13,520 --> 00:01:17,320
Mwen te panse, mwen te fè sa seryezman dènye
semèn, ki pa gen yon vle retounen?

31
00:01:17,320 --> 00:01:18,065
Mwen se pè.

32
00:01:18,065 --> 00:01:18,892

33
00:01:18,892 --> 00:01:21,100
Se konsa, twa lòt bagay sa yo
ke nou ap ale nan ale sou

34
00:01:21,100 --> 00:01:24,850
se Reoryantasyon, dosye mwen / O, ak
Lè sa a, endikasyon ak dinamik memwa.

35
00:01:24,850 --> 00:01:29,160
Mwen si ou ap tout super eksite sou
bagèt pi renmen sijè tout moun la,

36
00:01:29,160 --> 00:01:31,310
konsa senp yo konprann.

37
00:01:31,310 --> 00:01:33,130
Mwen si ke ou nèg tout te resevwa sa, dwa?

38
00:01:33,130 --> 00:01:39,510
>> Se konsa, premye bagay premye, redirection--
sa a se fondamantalman jis yon fason

39
00:01:39,510 --> 00:01:42,920
kontwole ki jan ou D '
bagay sa yo nan pwogram ou an,

40
00:01:42,920 --> 00:01:44,606
ki jan ou bagay sa yo pwodiksyon soti nan pwogram ou an.

41
00:01:44,606 --> 00:01:46,980
Fason prensipal ke ou nèg
yo te kominike avèk li

42
00:01:46,980 --> 00:01:51,650
se jis nan soti estanda
ak ekran ekri an lèt detache ou isit la.

43
00:01:51,650 --> 00:01:55,940
Men, gen fason yo
pipe-- jan nou wè isit la

44
00:01:55,940 --> 00:01:58,980
se youn nan kalite words-- nou an
nan tiyo ke enfòmasyon

45
00:01:58,980 --> 00:02:02,850
oswa ke done nan yon dosye ki sòti nan yon dosye.

46
00:02:02,850 --> 00:02:05,820
Se jis nan diferan fason pou
ap resevwa bagay sa yo nan pwogram ou an

47
00:02:05,820 --> 00:02:10,681
ak soti nan pwogram ou an, olye pou yo
jis enprime yo nan ekran sa a

48
00:02:10,681 --> 00:02:12,430
oswa Anthrax bagay
soti nan liy la lòd.

49
00:02:12,430 --> 00:02:13,760

50
00:02:13,760 --> 00:02:18,030
>> Se konsa, premye a se yon sèl ti kras
pi gran pase Lambda.

51
00:02:18,030 --> 00:02:22,085
Se konsa, li jis simagri output-- pwodiksyon an
nan yon dosye olye pou yo ekran an.

52
00:02:22,085 --> 00:02:23,620

53
00:02:23,620 --> 00:02:29,500
Se konsa, si ou te gen yon bagay ki enprime
"Alo, mond!" nan ekran an,

54
00:02:29,500 --> 00:02:32,400
si ou mete l 'olye pou
output.text, ki

55
00:02:32,400 --> 00:02:35,220
kreye sa a ranpli rele output.text.

56
00:02:35,220 --> 00:02:38,550
Men, lè ou louvri li, li pral
di "Hello, mond!" nan la.

57
00:02:38,550 --> 00:02:41,410
Sa a kapab itil super
si ou gen yon ton nan erè

58
00:02:41,410 --> 00:02:43,430
aktyèlman, jan nou wè nan yon sèl sa a.

59
00:02:43,430 --> 00:02:46,810
Si ou fè sa de Lambda, li pral
enprime mesaj yo erè.

60
00:02:46,810 --> 00:02:52,090
>> Se konsa, si w ap gen yon pwoblèm ak
konpile, li gen yon anpil nan erè

61
00:02:52,090 --> 00:02:56,770
ak w ap resevwa anbourbe desann nan ap
woulo liv atravè nan liy lòd ou

62
00:02:56,770 --> 00:02:59,110
nan tout yo, ou kapab
jis enprime yo nan yon dosye li an,

63
00:02:59,110 --> 00:03:02,130
louvri moute ki dosye pou ke ou
ka woulo liv atravè yo pi fasil.

64
00:03:02,130 --> 00:03:05,160
Mwen aktyèlman itilize ke yon
lè anpil mwen te debogaj

65
00:03:05,160 --> 00:03:07,970
181 psets mwen an pou aprantisaj machin.

66
00:03:07,970 --> 00:03:10,000
Se konsa, li kapab itil super pita sou.

67
00:03:10,000 --> 00:03:18,370
Li la tou itil si ou gen yon pwogram
ke petèt se génération yon bibliyotèk

68
00:03:18,370 --> 00:03:20,430
oswa génération kèk seri
nan strings, epi ou

69
00:03:20,430 --> 00:03:22,846
bezwen pou kapab wè ke
li nan génération yo byen.

70
00:03:22,846 --> 00:03:23,860

71
00:03:23,860 --> 00:03:25,160
Sa a se yon fason a fè sa.

72
00:03:25,160 --> 00:03:28,280
>> Se konsa, si ou enprime yo nan yon dosye, ou
ka egzaminen yo pi fasil, dwa?

73
00:03:28,280 --> 00:03:30,930
Parapò ak ap eseye woulo liv
nan liy lòd ou yo.

74
00:03:30,930 --> 00:03:32,740

75
00:03:32,740 --> 00:03:35,820
Lè sa a, yon sèl bagay yo sonje
se ke ak jis pi gwo a

76
00:03:35,820 --> 00:03:40,090
pase Lambda, si ou ap ekri
nan yon dosye ki deja exists--

77
00:03:40,090 --> 00:03:44,990
se konsa tankou si nou kouri premye a sa a
tan, nou mete l 'nan output.text,

78
00:03:44,990 --> 00:03:49,970
ak Lè sa a nou te gen yon pwogram dezyèm
ki enprime sa a kòm pwogram de

79
00:03:49,970 --> 00:03:54,250
ak te fè yon pi gran pase output.text,
li pral recouvrir that-- konsa

80
00:03:54,250 --> 00:03:56,715
recouvrir sa ki te tout tan nan
ki dosye yo kòmanse avèk yo.

81
00:03:56,715 --> 00:03:57,720

82
00:03:57,720 --> 00:04:00,750
>> Se konsa, si ou vle kole
nan yon dosye, jan nou wè isit la,

83
00:04:00,750 --> 00:04:04,779
ou jis fè de pi gran pase siy.

84
00:04:04,779 --> 00:04:05,820
Epi li pral kole nan li.

85
00:04:05,820 --> 00:04:06,750
Li pa pral recouvrir li.

86
00:04:06,750 --> 00:04:09,770
Se konsa, si ou bezwen kouri miltip
pwogram ak kalite kenbe

87
00:04:09,770 --> 00:04:13,170
tras nan sa yo tout yo
retounen nan ou nan yon dosye,

88
00:04:13,170 --> 00:04:14,190
sa a, se yon fason yo fè li.

89
00:04:14,190 --> 00:04:17,231
Si ou pa pran swen sa ki nan nan dosye ou
ak li a pèmèt yo dwe ranplase,

90
00:04:17,231 --> 00:04:19,204
ou ka jis sèvi ak yon pi gwo yon sèl pase.

91
00:04:19,204 --> 00:04:20,600

Se konsa, olye pou yo ap tann
pou yon èd memwa lòd,

114
00:05:30,520 --> 00:05:33,800
tankou lè ou te mande pou ou

Men, ou ta dwe konprann
fason ou ka itilize sa a.

161

anyen ak li soti nan la.

poukisa nou fè sa a se jis

li a pral ak sa nou vle enprime.

OK.

1115
00:53:56,660 --> 00:53:58,490
Jis pran yon ti kras
pandan y ap nan travay nan.

konprann sa chak pati

Sonje kijan tout kalite
gen yon gwosè diferan?

1130
00:54:28,390 --> 00:54:34,890
Se konsa, tankou yon doub oswa yon long lontan se
uit ak int se kat men Char se youn.

>> Se konsa, sa ou vle fè

pral depann de la

00:54:53,440 --> 00:54:53,940
Awesome.

Si ou te di konsèy

1146
00:55:20,170 --> 00:55:23,420
se li k ap pase yo ajou
li pa gwosè a nan yon int

1147
00:55:23,420 --> 00:55:25,950

kantite lajan an nan espas yon int ta pran.

1151
00:55:35,260 --> 00:55:36,260
Yon int se kat bytes.

Se pou nou kounye a di ke sa a te yon
Char konsèy, epi nou te ajoute yon sèl.

1163
00:56:10,850 --> 00:56:11,850
Ki sa ki li ta ka chanje?

00:56:11,850 --> 00:56:14,989

Se konsa, jis yon bagay yo sonje.

1172
00:56:23,820 --> 00:56:28,340
Jis lè ou ajoute yon sèl, li nan pa
ajoute yon sof si li nan yon Char.

1173

Li nan pandan l ajoute ki jan anpil
bytes kalite a ke li se,

ekwasyon sa a moute isit la.

kote eleman premye li yo se.

Paske nou konnen, nou ap
garanti, ke sa yo

yo pral yo dwe kontinyèl
blòk nan memwa.

etalaj ou a, ki se isit la.

1267

Ak nan ka sa a, tou sa etalaj ou
di ki kalite se, lè ou mete li pa youn,

konsa nou konnen ke yon moun

1295
01:01:58,880 --> 01:02:01,790
de bagay sa yo lè nou te pale pandan
premye seksyon nou an ansanm,

1296
01:02:01,790 --> 01:02:04,560
nou te gade yon swap
fonksyon kote li te

deyò sijè ki abòde lan fonksyon prensipal nou an.

1298
01:02:08,010 --> 01:02:14,370

ki te efektivman kopi.

>> E yon fwa swap fini
egzekite, li jis kite yon chemine.

Apre sa, yo te deja ale.

1303
01:02:27,050 --> 01:02:28,615
Nou pa t 'kapab fè anyen
avèk yo epi nou te tris

1304
01:02:28,615 --> 01:02:29,989
paske nou pa kapab swap valè nou yo.

1305
01:02:29,989 --> 01:02:31,070

nou pral wè, ou ka di,
