In C and C++ there are some function specifiers. The function specifiers are used to specify the functions property. C++ has inline function specifier. In C there is _Noreturn function specifier. This is used to denote that one function will not return anything.Example Live Demo#include int myAdd(int a, int b){ ... Read More
