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 system (this will impact the performance though)

c++ - Should I use size_t or ssize_t? - Stack Overflow typedef size_t intc; (instead of unsigned int) typedef ssize_t uintc; (instead of int) Because strlen, string, vector all use size_t, so I usually use size_t And I only use ssize_t when it may be negative But I find that: The unsigned integer types are ideal for uses that treat storage as a bit array Using an unsigned instead of an int to gain one more bit to represent positive
