[GD-General] meaning of sizeof(int) on all plateform

[<Lag...@wa...>]

Hello all,=20
I have some problem to define what represent sizeof(int).

IMO sizeof(int) =3D=3D memory bus address width

but on platforme like PS2, you have a bus of 128 and sizeof(int) =3D=3D =
32.

i have seen elsewherre that sizeof(int) =3D=3D size of a register.

Is someone have some information on this point ?
thanks

AFAIK, it depends on the OS and processor architecture. So on DOS, it was
16bit, or 2 bytes, on Windows >3.x, it is 32bit, or 4 bytes. On 64bit
windows, int is 64bit=>8 bytes. It's the size of the memory address.

sizeof(int)=3Dsizeof(void*)=3Dsizeof(pointer)
sizeof(short)=3Dsizeof(WORD)=3D2
sizeof(long)=3Dsizeof(DWORD)=3D4
sizeof(__int64)=3Dsizeof(LARGE_INTEGER)=3D8
sizeof(char)=3Dsizeof(BYTE)=3D1
