A function declared and/or defined within a class.

A member function is a procedure that whose signature is declared inside a class. This function takes an implicit argument of the same type as the containing class and is only accessible via an object of that type. When the function is static, no implicit argument is needed, but the function must be invoked via the class' scope. In contrast, a free-function does not have an implicit argument of the class type nor is invoked via a class scope.
