Oke, kite la ale pi devan epi
aplike pwogram sa a.

kite a gen ladan string.h.

pase lèt yo majuskul.

30
00:01:49,240 --> 00:01:53,490
Se konsa, si nou vle konvèti soti nan miniskil
majuskul, li ta dwe

31
00:01:53,490 --> 00:01:57,210
sifi, reyèlman, fè soustraksyon
32 soti nan opinyon itilizatè a la.

32
00:01:57,210 --> 00:02:01,330
Oswa plis jeneralman, jis fè soustraksyon ki
diferans ki genyen ant yon yon miniskil ak yon

nan fen jou a 32.

41
00:02:29,360 --> 00:02:31,230
Men, mwen pa gen sonje
ke li nan 32.

42
00:02:31,230 --> 00:02:34,150
Mwen ka pèmèt òdinatè a nan figi konnen
sa ki diferans ki genyen ant miniskil

prezimableman yon lèt miniskil nan yon

pi ba valè, sètadi yon valè ki kat
sou yon ekivalan majuskul.

00:02:48,100 --> 00:02:51,240
Se pou nou kounye a sove, konpile,
epi kouri pwogram sa a.

Mwen se trè senp, ak lajman pou

nan tout ka pi ba e kounye a, frape antre nan,
