This is the simple and logic building program in C++ for beginners. The program will find the factorial of a given number.

Source Code

#include "stdafx.h"
#include <iostream>
#include <string>
using namespace std;
int main()
{
 cout<<"\a\n\n\n"
  <<"\t******************************************************"<<endl
  <<"\t**                                                  **"<<endl

  <<endl;
 cout<<"";

 int yourNember, incrementor, factorial = 1;
 
        cout<<"Enter your number "<<endl;

        cin>>yourNember;

        if ( yourNember < 0 )
            cout<<"-Negative Number Error"<<endl;
        else
        {
            for ( incrementor = 1 ; incrementor <= yourNember ; incrementor++ )
                factorial = factorial*incrementor;
             cout<<"Factorial of "<<yourNember<<" is = "<<factorial<<endl;
        }
 cout <<endl;
 system("pause");
 return 0;
}
