WebJul 30, 2024 · Here we will see what are the differences between size_t and int in C++. If we consider the standard, both are integers of size 16 bits. On a typical 64-bit system, the size_t will be 64-bit, but unsigned int will be 32 bit. So we cannot use them interchangeably. One standard recommendation is that the size_t be at most as big as an unsigned long.

I previously covered the size_t type in C, which is used to represent the size of an allocated block of memory. But lots of C functions use a type called ssize_t. What’s that? What is the extra s? In short, ssize_t is the same as size_t, but is a signed type - read ssize_t as “signed size_t”. affidea elias
