C++ Overriding

What is overriding in C++?

• Redefining a base class function in the derived class to have our own implementation is referred as overriding.
• Often confused with overloading which refers to using the same function name but with a different signature. However in overriding the function signature is the same.

EXAMPLE: Demonstrate the usage of overriding

#include <iostream>
using namespace std;

class Base {
    public:
        virtual void myfunc() {
            cout << "Base::myfunc .." << endl;
        }
};

class Derived : public Base {
    public:
        void myfunc() {
            cout << "Derived::myfunc .." << endl;
        }
};

void main()
{
    Derived d;
    d.myfunc();
}

OUTPUT:-
Derived::myfunc ..
