    In C++, a virtual function is a member function of a base class that can be redefined in derived classes. The virtual keyword is used to declare a virtual function in the base class. 

      • Runtime polymorphism: Virtual functions allow objects of different classes to be treated as objects of a common base class. 
      • Dynamic dispatch: Virtual functions select the best function implementation based on the object’s type at runtime.
      • Code efficiency: Virtual functions can streamline development and improve code efficiency.
