Can static functions be virtual in C++?

　　In C++, a static member function of a class cannot be virtual.

　　For example, below program gives compilation error.

 1 #include<iostream>

 2 using namespace std;

 3

 4 class Test

 5 {

 6 public:

 7     // Error: Virtual member functions cannot be static

 8     virtual static void fun()

 9     {

10     }

11 };

　　Also, static member function cannot be const and volatile.

　　Following code also fails in compilation.

 1 #include<iostream>

 2

 3 using namespace std;

 4

 5 class Test

 6 {

 7    public:

 8       // Error: Static member function cannot be const

 9       static void fun() const

10       {

11       }

12 };
