Virtual functions[C++]

  
  #include<iostream>
using namespace std;
  
class base {
public:
    virtual void print()
    {
        cout << "print base class\n";
    }
  
    void show()
    {
        cout << "show base class\n";
    }
};
  
class derived : public base 
{
public:
    void print()
    {
        cout << "print derived class\n";
    }
   void show()
    {
        cout << "show derived class\n";
    }
};
 int main()
{
    base *bptr;
    derived d;
    bptr = &d;
      // Virtual function, binded at runtime
    bptr->print();
      // Non-virtual function, binded at compile time
    bptr->show();
   return 0;
}

     

           

Note: Need to be arranged in compiler after copied

   

 OutPut:

print derived class
show base class
