The bit types in a machine are nothing but memory address, that it can hold. 32 bit machines can hold 2^32 and 64 bit machines can hold 2^64 address spaces.

WebNote however that C++ allows enums with initializers outside of the int range, and for those enums the size will of course also be larger. For example, if you have enum bar { a, b = 1LL << 35 }; then your enum will be larger than 32 bits (most likely 64 bits) even on a system with 32 bit ints (note that in C that enum would not be allowed).
