9.17.4.Call base virtual function explicitly

#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( )
