- 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
