Difference between size and length methods?
What is the difference between .size() and .length ? Is .size() only for arraylists and .length only for arrays?
What''s 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
What does the C++ standard say about the size of int, long?
If the size of the int is that important one can use int16_t, int32_t and int64_t (need the iostream include for that if I remember correctly). What''s nice about this that int64_t should not have issues on a 32bit
