#include <iostream>

using namespace std;

class Base {
public:
   virtual void foo( ) {cout << "Base::foo( )" << endl;}
};

class Derived : public Base {
public:
   virtual void foo( ) {cout << "Derived::foo( )" << endl;}
};

int main( ) {
   Derived* p = new Derived( );

   p->foo( );       // Calls the derived version
   p->Base::foo( ); // Calls the base version
}

Derived::foo( )
Base::foo( )
