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
ki fè sans a tout moun?

92

>> Oratè 1: Dwa.

96
00:04:34,810 --> 00:04:40,450
Se konsa, li ta fondamantalman jis konplètman
recouvrir sa ki te gen yo kòmanse avèk yo.

97
00:04:40,450 --> 00:04:44,260
Si sa a ranpli isit la a,

ki ankò ak yon pi gwo yon sèl

kòm tankou li ranplase dosye a.

100
00:04:51,920 --> 00:04:54,824
Menm jan ak lè w ap ekonomize yon Pawòl
dokiman ak ou sove kòm,

00:04:54,824 --> 00:04:57,365
epi ou kenbe menm non yo, ak
li konplètman ranplas l--

102
00:04:57,365 --> 00:04:58,680
sa a se sòt nan menm nan bagay.

00:04:58,680 --> 00:05:00,380

00:05:00,380 --> 00:05:03,550
Nenpòt moun ki gen nenpòt kesyon sou

106
00:05:05,051 --> 00:05:05,550
Awesome.

107
00:05:05,550 --> 00:05:11,440
>> Se konsa, evidamman, si ou ranvèse a
flèch direksyon, li ka fè opinyon.

109
00:05:13,090 --> 00:05:19,960

tankou Seza tande kòz oswa Visioneer

ou te gen yon liy lòd agiman

ki aktyèlman opinyon li.

112
00:05:24,960 --> 00:05:27,410
Sa a se yon lòt fason yo fè sa.

113
00:05:27,410 --> 00:05:30,520
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
mesaj nan Seza tande kòz oswa Visioneer,

115
00:05:33,800 --> 00:05:36,490
si ou te gen yon dosye tèks
ki te gen mesaj ou a,

116
00:05:36,490 --> 00:05:38,280
ou ta ka jis tape l 'nan sa.

3 mwens pase tèks opinyon flèch, ki

mande pou enfòmasyon nan men gwoup itilizatè a,

li ta deja gen li paske
ou te tape nan sa a dosye.

122
00:05:57,360 --> 00:05:58,830
Se jis yon lòt fason.

123
00:05:58,830 --> 00:06:02,445
Jis yon ranvèse nan output--
jis opinyon pou done ou.

00:07:30,932 --> 00:07:32,890
Ou pwobableman pa pral gen
fè twòp ak li.

160
00:07:32,890 --> 00:07:35,670
Men, ou ta dwe konprann
fason ou ka itilize sa a.

161
00:07:35,670 --> 00:07:38,910
E gen kèk ka ki
ou ta ka vle sèvi ak li.

Men, ou pa ka vrèman fè
anyen ak li soti nan la.

173
00:08:16,370 --> 00:08:18,950
Si ou sere nan yon tèks
dosye, sa a, toudenkou

174

ou gen sa a done ke w ap pèmèt
manipile oswa mete l 'nan yon dosye,

Youn nan rezon ki
poukisa nou fè sa a se jis

bezwen yo kreye yon referans

sote pòsyon nan memwa.

fason ou ka sote bagay

Klè?

667
00:32:36,227 --> 00:32:36,981
Wi.

668
00:32:36,981 --> 00:32:40,365
>> ODYANS: Se konsa, lè li ekri sa a

Mwen santi mwen tankou w ap tout
jwenn li, ki se gwo.

676
00:32:55,840 --> 00:32:57,290

677
00:32:57,290 --> 00:32:57,790
OK.

678
00:32:57,790 --> 00:33:05,960
Se konsa, tounen nan show-- glise m '
Mwen renmen lè bagay sa yo travay.

679
00:33:05,960 --> 00:33:08,674
OK, bagèt Èske ou nèg eksite?

680
00:33:08,674 --> 00:33:09,465
Endikasyon yo se gwo.

681
00:33:09,465 --> 00:33:11,581

682

Yo pran yon ti jan
yo vlope tèt ou alantou.

683
00:33:13,580 --> 00:33:15,288
Sa a se dezyèm ane mwen
ansèyman endikasyon.

684
00:33:15,288 --> 00:33:16,850
Apre sa, mwen panse ke mwen finalman te resevwa li.

685
00:33:16,850 --> 00:33:18,650
Se konsa, si ou lite, li nan OK.

686
00:33:18,650 --> 00:33:19,940

687
00:33:19,940 --> 00:33:24,070
Kòm mwen te di anvan, desen foto
ede anpil ak bagay sa yo nan CS,

688
00:33:24,070 --> 00:33:27,400
kòm anpil jan mwen panse ke moun ki gen tandans
yo panse oh, nou ap nan yon òdinatè.

689
00:33:27,400 --> 00:33:28,399
Nou ta dwe jis kòd.

690
00:33:28,399 --> 00:33:30,190
Foto desen No--
pral reyèlman ede ou.

691
00:33:30,190 --> 00:33:32,773
Apre sa, mwen reyèlman ankouraje w
tiyo nan bò kindergartner ou

692
00:33:32,773 --> 00:33:35,010

Paske li ap ede ou.

694
00:33:36,110 --> 00:33:39,380
Men, si ou wè m 'nan lè biwo louvri, Mwen
yo pral pote alantou pil nan papye

695
00:33:39,380 --> 00:33:41,580
ak plim desen bagay sa yo soti.

696
00:33:41,580 --> 00:33:44,370
>> Se konsa, sitou ak
bagèt desine foto.

697
00:33:44,370 --> 00:33:47,970
E mwen panse ke nou ap aktyèlman ale nan
gen desen kèk foto isit la tou.

698
00:33:47,970 --> 00:33:51,270
>> Se konsa, ou nèg tout te rive nan wè Binky,
sa a claymation bagay fre.

699
00:33:51,270 --> 00:33:54,720
Apre sa, nou panse ke li nan vrèman komik lè
li te eksploze nan yon pakèt moun sou moso.

700
00:33:54,720 --> 00:33:56,280

701
00:33:56,280 --> 00:33:57,755
Li nan kèk soulajman komik pou klas la.

702
00:33:57,755 --> 00:34:02,140

703
00:34:02,140 --> 00:34:05,900
C [fèbl] gwo kapasite sa a
pou kapab kontwole memwa.

704
00:34:05,900 --> 00:34:10,090
Lè li nan youn nan bagay ki ki vrèman
fè li tankou yon lang pwisan.

705
00:34:10,090 --> 00:34:13,469
Men, avèk gwo pouvwa vini
gwo responsablite.

706
00:34:13,469 --> 00:34:16,230
Epi bagay sa yo fou ka rive
si ou pa fè atansyon.

707
00:34:16,230 --> 00:34:18,560
Se konsa, lè w ap itilize
endikasyon, ou vle fè

708
00:34:18,560 --> 00:34:21,440
w ke ou reyèlman konprann
ekzakteman ki sa ou ap fè.

709
00:34:21,440 --> 00:34:25,530
Èspere ke pwochen ti jan a ti kras nan
tan ap ede ou reyèlman konprann

710
00:34:25,530 --> 00:34:27,850
endikasyon, Ki jan yo sèvi ak yo,
ak kouman yo manipile yo.

711
00:34:27,850 --> 00:34:29,170

712
00:34:29,170 --> 00:34:33,460
>> Se konsa, memwa mwen si ke nou te
wè dyagram sa a anvan.

713
00:34:33,460 --> 00:34:38,540
Se konsa, sa a se jis yon dyagram senp nan
ki jan bagay ta ka dwe estoke memwa.

714
00:34:38,540 --> 00:34:43,145
Se konsa, ou fondamantalman gen sa yo
gwo ranje nan blòk yon sèl multiple

715
00:34:43,145 --> 00:34:46,000
se sa nou gen isit lan-- ti tay
ogmantasyon pa youn chak fwa.

716
00:34:46,000 --> 00:34:51,810
Sa a se nan Egzagòn [fèbl]
se konsa uit-ti jan blòk.

717
00:34:51,810 --> 00:34:55,510
Epi se chak blòk ki asosye
ak kèk adrès ekzadesimal.

718
00:34:55,510 --> 00:34:58,750
Se konsa, si ou te janm wè nan
0x, ki nan jis notating

719
00:34:58,750 --> 00:35:00,670
ke li nan yon adrès ekzadesimal.

720
00:35:00,670 --> 00:35:03,970
Ou ka asime sa a vle di
kèk adrès nan memwa.

721
00:35:03,970 --> 00:35:06,935
Nou ap pale de adrès memwa
chak fwa ou wè ekzadesimal.

722
00:35:06,935 --> 00:35:10,420

723
00:35:10,420 --> 00:35:14,630
>> Nou gen antye yo se varyab,
flote yo se varyab ki magazen.

724
00:35:14,630 --> 00:35:16,260
Se konsa, antye antye magazen.

725
00:35:16,260 --> 00:35:17,430
Flote magazen flote.

726
00:35:17,430 --> 00:35:20,260
Se konsa, nou menm tou nou gen endikasyon
ki adrès magazen memwa.

727
00:35:20,260 --> 00:35:21,660
Sa se yon sòt de kat.

728
00:35:21,660 --> 00:35:24,240
Endikasyon yo se sèlman
pou adrès memwa.

729
00:35:24,240 --> 00:35:25,780

730
00:35:25,780 --> 00:35:27,292
Se konsa, sa a, se tankou kalite ou a.

731
00:35:27,292 --> 00:35:29,550

732
00:35:29,550 --> 00:35:34,470
Aparèy ou se 32-ti jan, ki vle di
ki adrès memwa ou se kat bytes.

733
00:35:34,470 --> 00:35:37,830
Se konsa, nenpòt konsèy ke ou gen
se tou pral fè kat bytes.

734
00:35:37,830 --> 00:35:43,200
Oswa lòt moun si li nan kat bytes,
memwa se kat bytes.

735
00:35:43,200 --> 00:35:44,790
Endikasyon magazen memwa.

736
00:35:44,790 --> 00:35:46,430
Se poutèt sa, yo ap kat bytes.

737
00:35:46,430 --> 00:35:48,460
Cool-- jis vle ranfòse sa.

738
00:35:48,460 --> 00:35:50,120

Mwen pa konnen kijan anpil nan nou
se fanatik xkcd, men mwen renmen xkcd.

Ou gen yon kalite.

Ou gen yon non.

Dwa?

748
00:36:04,810 --> 00:36:10,410
Sa a ki sa nou gen la.
[? Egzagòn?] Zetwal vle di li nan yon konsèy,

nou konnen nou ap estoke yon Int la.

Avèk yon konsèy, li
kenbe yon adrès memwa.

Se konsa, nan ka sa a, nou gen
kèk value-- kite a di kat.

759

Kat se nan adrès youn.

760

826
00:39:52,130 --> 00:39:57,560
Epi comercial a ap ban nou
adrès la nan yon bagay.

827
00:39:57,560 --> 00:40:00,780
Se konsa, nan ka sa a, li nan adrès ki nan x.

837
00:40:25,740 --> 00:40:28,450
w ap ale nan wè montre nan bagay sa yo.

838
00:40:28,450 --> 00:40:31,470
Epi yon blòk montre nan yon lòt

flèch sa a nan sa a ti moso memwa.

854
00:41:11,430 --> 00:41:15,380
Ak ban nou sa ki nan nan li, ki se 5.

855

856
00:41:18,840 --> 00:41:20,120
ki fè sans?

857
00:41:20,120 --> 00:41:22,769
nenpòt moun ki bezwen m 'yo ale nan
sa ankò, oswa plis tou dousman?

00:41:28,840 --> 00:41:31,930

863
00:41:31,930 --> 00:41:37,205
Lè nou kòmanse, nou tout dakò nou gen
kèk ti moso nan memwa sa a, se yon varyab

864
00:41:37,205 --> 00:41:40,890
x ke nou mete egal a 5.

865
00:41:40,890 --> 00:41:42,910
Nou pa kontwole kote li se nan memwa.

866

Se konsa, plas sa a se jis
abitrèman asiyen.

00:41:49,230 --> 00:41:50,420

871
00:41:50,420 --> 00:41:53,330
Lè sa a, nou inisyalize yon konsèy nan yon int.

872

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

1164
00:56:11,850 --> 00:56:14,989

1165
00:56:14,989 --> 00:56:16,030
Konbyen bytes se yon Char?

1166

1171
00:56:22,571 --> 00:56:23,820
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
00:56:28,340 --> 00:56:34,190
Li nan pandan l ajoute ki jan anpil
bytes kalite a ke li se,

1174
00:56:34,190 --> 00:56:36,960
ki se poukisa nou gen
ekwasyon sa a moute isit la.

1175

lè nou te fè y plis egal yon sèl.

Ki sa ki nan nan li, sa ki nan
nan x, pa chanje.

1182

ka, bagay la analoji

01:09:39,160 --> 01:09:41,200
Se konsa, poukisa pa nou libere strings?

1482
01:09:41,200 --> 01:09:43,204
>> Oratè 1: Ou sèlman
gratis si w ap mallocing.

1483
01:09:43,204 --> 01:09:44,620
ODYANS: Oh, si w ap mallocing.

1484
01:09:44,620 --> 01:09:47,399
Oratè 1: Se konsa, malok
ak gratis de bagay

01:09:47,399 --> 01:09:49,000
ke ou ta dwe toujou gen ansanm.

1486
01:09:49,000 --> 01:09:51,630
f louvri, f fèmen, de bagay
ou ta dwe gen yo ansanm.

1487
01:09:51,630 --> 01:09:54,471
Nan de ka sa yo, tcheke pou nil.

1488
01:09:54,471 --> 01:09:54,971
Wi.

1489
01:09:54,971 --> 01:09:57,130
>> ODYANS: Se konsa gratis se jis
sa ki pèmèt yon lòt bagay

1490
01:09:57,130 --> 01:09:59,690

Pwogram sa a itilize li?

1491
01:09:59,690 --> 01:10:01,946
>> Oratè 1: Li nan jis li di:
OK, mwen fè ak sa a.

1492
01:10:01,946 --> 01:10:03,320
Ou pa bezwen kenbe l 'alantou.

1493
01:10:03,320 --> 01:10:05,340

1494
01:10:05,340 --> 01:10:08,190
Sinon òdinatè w lan pral
jis renmen eseye epi kenbe l 'la.

1495
01:10:08,190 --> 01:10:10,910
Lè sa a, ou can't-- li kouri
nan pwoblèm memwa pita.

1496
01:10:10,910 --> 01:10:13,660
Ou toujou vle libere li paske
li di òdinatè w lan, OK, mwen se

1497
01:10:13,660 --> 01:10:15,190
fè ak plas sa a nan memwa.

1498

Ou ka gen l 'tounen
pou mwen pou m sèvi ak pita.

Cool?

1501
01:10:20,500 --> 01:10:21,320
Wi.

1502
01:10:21,320 --> 01:10:26,950
>> ODYANS: Se konsa, nou itilize% d nan jis
paske yon doub ki nan vini tounen,

1503
01:10:26,950 --> 01:10:28,330
oswa poukisa is-- [fèbl].

1504
01:10:28,330 --> 01:10:30,170

1505
01:10:30,170 --> 01:10:31,620

01:10:32,760 --> 01:10:35,052

1508
01:10:35,052 --> 01:10:36,135
Nenpòt kesyon minit sot pase a?

1509
01:10:36,135 --> 01:10:38,310

1510
01:10:38,310 --> 01:10:38,985
Ale pi devan.

1511
01:10:38,985 --> 01:10:40,610
ODYANS: Mwen jis gen yon kesyon rapid.

1512
01:10:40,610 --> 01:10:50,200
Se konsa, varyab la ptr, that's--
tankou, ak int * ptr = malok a,

1513
01:10:50,200 --> 01:10:54,142
ki nan jis di li nan
montre nan yon plas nan memwa

1514
01:10:54,142 --> 01:10:55,600
Oratè 1: Èske ou vle [fèbl]?

1515
01:10:55,600 --> 01:10:58,050
ODYANS: --that nan la
gwosè of-- pa gen okenn, li nan OK.

1516
01:10:58,050 --> 01:11:01,292
Men, li la jis montre nan yon plas nan
memwa sa a, se jis tankou kat bytes.

1517
01:11:01,292 --> 01:11:02,000
Oratè 1: Dwa.

1518
01:11:02,000 --> 01:11:03,030

1519
01:11:03,030 --> 01:11:07,070
Se konsa, malok gwosè a nan int di,
OK, mwen pral ale kouri koupe,

1520
01:11:07,070 --> 01:11:08,780
jwenn kat bytes nan memwa pou ou.

1521
01:11:08,780 --> 01:11:10,700
Lè li jwenn ke kat
bytes nan memwa, li

1522
01:11:10,700 --> 01:11:14,030
ba ou tounen adrès la
nan kote li kòmanse,

1523
01:11:14,030 --> 01:11:16,160
ak se sa ki estoke
nan konsèy, oswa ptr.

01:11:16,160 --> 01:11:17,510

01:11:17,510 --> 01:11:18,010
Bon.

Ou nèg gade mwens konfonn pase sa pifò

Kòm toujou, ou nèg ta dwe gen tout

01:11:27,960 --> 01:11:32,769
Mwen konnen te gen kèk bankal
bagay kote li di, fòmil pa valab

1532
01:11:32,769 --> 01:11:33,310

Vini jwenn mwen.
