Function Overriding in C++

Function Overriding:

Redefining a base class function in the derived class to have our own implementation is referred as overriding.

The signature of the function will be same.

For example:-

Class m

{

            public:

                        void display()

                        {

                                    cout<<”Base class function”;

                        }

};

class n:public m

{

            public:

                        void display()

                        {

                                    vout<<”Derived class function”;

                        }

};

void main()

{

            n obj;

            obj.display();

            obj.show();

            obj.m::display();

            getch();

}
