Quick question, as far as it goes in C++, what are the sizes of (i.e. bits, or bytes) of ints, and pointers? Specifically which is larger?

In C/C++... A byte is at least 8 bits. char is exactly 1 byte short is at least 16 bits. int is at least 16 bits. long is at least 32 bits. Also: short <= int <= long. Finally: sizeof(int) == sizeof(unsigned int).
A pointer's size is determined by the platform, and has no guaranteed size. Therefore, my answer is, Both and neither.
