Can static functions be virtual in C++?
  • Difficulty Level : Easy
  • Last Updated : 21 Jun, 2017

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




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