What does the C++ standard state the size of int, long type to be?

Question

I\'m looking for detailed information regarding the size of basic C++ types. I know that it depends on the architecture (16 bits, 32 bits, 64 bits) and the compiler.

Answer 1

unsigned char bits = sizeof(X) << 3;

where X is a char,int,long etc.. will give you size of X in bits.
