The guarantee you get is that
sizeof(char) == 1. There are no other guarantees, including no guarantee thatsizeof(int *) == sizeof(double *).In practice, pointers will be size 2 on a 16-bit system (if you can find one), 4 on a 32-bit system, and 8 on a 64-bit system, but there’s nothing to be gained in relying on a given size.
