Hi
Here is an excerpt from the C++ standard about the size of fundamental types
(clause 5.3.3) :
sizeof(char), sizeof(signed char) and sizeof(unsigned char) are 1; the result
of sizeof applied to any other fundamental type (3.9.1) is
implementation-defined. [Note: in particular, sizeof(bool) and
sizeof(wchar_t) are implementation-defined.69) ]
Regards
Patrick
