Perbezaan Antara Unsigned Dgn X De Unsigned

[otai_g 3]

aku ada 1 soalan yg betul2 memeningkan kepala aku.harap2 sapa tlng explain.

apa beza di antara declaration berikut:

usnigned long dgn long sahaja &

unsigned char dgn char sahaja.

sbg cth

unsigned long kueyTiowGoeng;
unsigned char kariAyam;

mengapakah perlu ada unsigned sebelum data type tu n apa efek dia kalo x taruk unsiged?

try tgk link ni : http://msdn.microsoft.com/en-us/library/s3f49ktz(VS.80).aspx

dgn erti kate lain data-type limit

eg : usnigned long = 0 to 4,294,967,295

unsigned char = 0 to 255

char = –128 to 127
