WebFor scanf, you need to use %hu since you're passing a pointer to an unsigned short. For printf, it's impossible to pass an unsigned short due to default promotions (it will be promoted to int or unsigned int depending on whether int has at least as many value bits as unsigned short or not) so %d or %u is fine. WebIntroduction to C++ size_t. In C++, size_t is defined as the type to represent the object size in bytes which is an unsigned integer type provided by the standard library for representing the object’s size and counting and this is a type returned by the sizeof operator which is also used as the return type of many different cstring functions such as strcspn, strlen, strspn, …
