what is polymorphism with example program in c#, and C++

Here's the C++ equivalent of the C# Animal/Dog example in the last of Satyapriya's links:

#include "stdafx.h"

#include

using namespace std;

class Animal

{

public:

Animal()

{

cout << "Animal constructor" << endl;

}

void Greet()

{

cout << "Animal says Hello" << endl;

}

void Talk()

{

cout << "Animal talk" << endl;

}

virtual void Sing()

{

cout << "Animal song" << endl;

}

};

class Dog : public Animal

{

public:

Dog()

{

cout << "Dog constructor" << endl;

}

void Talk()

{

cout << "Dog talk" << endl;

}

void Sing()

{

cout << "Dog song" << endl;

}

};

int _tmain(int argc, _TCHAR* argv[])

{

Animal *a1 = new Animal();

a1->Talk();

a1->Sing();

a1->Greet();

cout << "\n";

Animal *a2 = new Dog();

a2->Talk();

a2->Sing();

a2->Greet();

cout << "\n";

Dog *d1 = new Dog();

d1->Talk();

d1->Sing();

d1->Greet();

cout << "\n";

return 0;

}

The output, as expected, should be:

Animal constructor

Animal talk

Animal song

Animal says Hello

Animal constructor

Dog constructor

Animal talk

Dog song

Animal says Hello

Animal constructor

Dog constructor

Dog talk

Dog song

Animal says Hello

}

The output, as expected, should be:

Animal constructor

Animal song
Animal says Hello

Animal constructor
Dog constructor
Animal talk
Dog song
Animal says Hello

Animal constructor
Dog constructor
Dog talk
Dog song
