static furnciton Virtula and const

In C++, a static member function of a class cannot be virtual. For example, below program gives compilation error.

#include   using namespace std;       class Test {    public:       // Error: Virtual member functions cannot be static            virtual static void fun()  { } };

Also, static member function cannot be const and volatile. Following code also fails in compilation.

#include   using namespace std;       class Test {    public:       // Error: Static member function cannot be const       static void fun() const { } };
