Answer Posted / rama
When we use the same function name in both the base and the
derived classes, the function in base class is declared as virtual...we must access virtual function through the use of a pointer declared as a pointer to the base class..
In other words, virtual function is defined in the base class,it need not be necessarily redefined in the derived class. In such cases,the respective calls will invoke the base class function.
