Factorial Using Pointers in C++

A simple program that I wrote for my programming class before in college factorial program using pointers in C++. What does the program will do is to ask the user to give a number and then our program will compute its factorial equivalent.

Program Listing

#include <iostream>

using namespace std;

int factorial (int num)

{

 if (num==1)

  return 1;

 return factorial(num-1)*num;

}

main() {

    int value=0;

    int *p;

    cout << "\t Recursion using Pointers";

    cout << "\n\n";

    cout << "Enter a Number :=> ";

    cin >> value;

    p = &value;

    cout << "\n";

    cout <<"The factorial value of " << value

        << " is " << factorial(value) << ".";

    cout << "\n\n";

    system("pause");
