CPP program to demonstrate runtime polymorphism

In this article we will look at how to implement a CPP program to demonstrate runtime polymorphism. A C++ program is provided below to illustrate runtime polymorphism. Program is as follows:

#include <iostream>
using namespace std;
class Animal
{
	public:
		virtual void sound() = 0;
		virtual void move() = 0;
};
class Dog : public Animal
{
	public:
		void sound()
		{
			cout<<"Bow wow wow"<<endl;
		}
		void move()
		{
			cout<<"Dog is moving"<<endl;
		}
};
class Cat : public Animal
{
	public:
		void sound()
		{
			cout<<"Meow meow meow"<<endl;
		}
		void move()
		{
			cout<<"Cat is moving"<<endl;
		}
};
int main()
{
	Animal *a;
	a = new Dog();
	a->sound(); //run-time polymorphism
	a = new Cat();
	a->sound(); //run-time polymorphism
	return 0;
}

Output for the above program is as follows:

Bow wow wow
Meow meow meow
