Chapter 91. Rely on types, not on representations > Discussion
Discussion
The C++ Standard makes few guarantees about how types are represented in memory:
Base two is guaranteed for integral numbers.
Two’s complement is guaranteed for negative integral numbers.
Plain Old Data (POD) types have C-compatible layout: Member variables are stored in their order of declaration.
int holds at least 16 bits.
