00:00:12,286 --> 00:00:13,280
>> ROB BOWDEN: Hi.

4
00:00:13,280 --> 00:00:16,340
Mwen se Rob, e kite yo jwenn
moun ki fè l '.

5
00:00:16,340 --> 00:00:20,070
Se konsa, kòmanse ak modèl la ki
copy.c deja ba nou, nou wè ke

6
00:00:20,070 --> 00:00:22,380
pi fò nan kòd la ki pral
yo dwe menm bagay la.

7
00:00:22,380 --> 00:00:25,110
Nou pral tcheke a asire w
gen nan yon infile ak outfile

8
00:00:25,110 --> 00:00:29,610
espesifye nan liy lan lòd, nou ap
pral ouvè infile a pou lekti,

9
00:00:29,610 --> 00:00:33,490
nou pral louvri outfile la pou
ekri, epi finalman, nou pral

10
00:00:33,490 --> 00:00:38,780
li nan Tèt infile a, tcheke yo
asire w ke li nan yon bitmap ki valab, ekri

11
00:00:38,780 --> 00:00:43,210
tèt yo outfile la, menm jan
te copy.c fè, epi nou ap ale nan

12
00:00:43,210 --> 00:00:46,080
repňte sou infile la
eskane liy nan piksèl.

13
00:00:46,080 --> 00:00:49,170
>> Epi, koulye a nou wè se sèlman nan
chanje sa a dosye.

14
00:00:49,170 --> 00:00:53,680
Se konsa, nou li nan yon trip soti nan infile la
kòm copy.c fè, men olye pou yo

15
00:00:53,680 --> 00:00:57,240
imedyatman ekri trip la a
outfile, nou ap ale nan chanje an

16
00:00:57,240 --> 00:00:58,190
pixel done.

17
00:00:58,190 --> 00:01:02,010
Se konsa, nou ap ale nan mete done yo ble
jis 0, nou pral mete vèt la

18
00:01:02,010 --> 00:01:06,150
a 0, kite nou ak sèlman wouj la, epi
Lè sa a, nou pral ekri ke yo

19
00:01:06,150 --> 00:01:07,200
outfile la.

20
00:01:07,200 --> 00:01:11,830
Lè sa a, padding an ki pral fè
ekzakteman menm bagay la jan li te ye nan copy.c.

21
00:01:11,830 --> 00:01:14,150
Finalman, fèmen dosye yo, retounen 0.

22
00:01:14,150 --> 00:01:16,070
>> Se konsa, kite a wè sa ki rive.

23
00:01:16,070 --> 00:01:24,280
Se pou yo fè whodunit,. / Whodunit,
clue.bmp, ak pèmèt revele ke bitmap.

24
00:01:24,280 --> 00:01:25,530
Se pou yo gade nan dosye a.

25
00:01:25,530 --> 00:01:27,900

26
00:01:27,900 --> 00:01:30,360
Lè nou wè Milo Bannann Bradstreet li.

27
00:01:30,360 --> 00:01:31,920
Non mwen se Rob, ak sa a te whodunit.
