- Whats sizeof(size_t) on 32-bit vs the various 64-bit data models?
An individual process in an OS might only be allowed to reserve up to 4GB RAM or less, which means size_t would only need to be 32-bit while pointers are 64-bit 32-bit wide size_t wouldn't necessarily affect any operations as long as the CPU has the capability to add subtract a 32-bit wide value to from a 64-bit wide value
- Whats the difference between size_t and int in C++?
