Cross-platform primitive data types in C++

Question

Unlike Java or C#, primitive data types in C++ can vary in size depending on the platform. For example, int is not guaranteed to be a 32-bit integer. Various compi

Answer 1

Part of the C99 standard was a stdint.h header file to provide this kind of information. For instance, it defines a type called uint32_t. Unfortunately, a lot of compilers don't support stdint.h. The best cross-platform implementation I've seen of stdint.h is here: http://www.azillionmonkeys.com/qed/pstdint.h. You can just include that in your project.

If you're using boost, I believe it also provides something equivalent to the stdint header.
