Why static member of class can not be overloaded in c++?

Question

#include<iostream>
 class Test {
   static void fun() {}
   void fun() {} // compiler error
};

int main()
{
   getchar();
   return 0;
}

Output:

|4|error: ‘void Test::fun()’ cannot be overloaded|

Answer 1

It is not possible as the standard forbids it directly.

Quoting the C++14 standard document, chapter § 13.1, "Overloadable declarations"

2. Certain function declarations cannot be overloaded

   • Function declarations that differ only in the return type cannot be overloaded.

   • Member function declarations with the same name and the same parameter types cannot be overloaded if any of them is a static member function declaration. [....]
