Factorial of a Number using Recursion and loop


Write a C++ Program to find Factorial of a Number using Recursion and loop. Here’s simple Program to find Factorial of a Number using Recursion and loop in C++ Programming Language.


Factorial of any number is the product of an integer and all the integers below it for example factorial of 4 is
4! = 4 * 3 * 2 * 1 = 24


Factorial of a Number using For Loop

Here is source code of the C++ Program to find Factorial of a Number using for loop. The C++ program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.


SOURCE CODE : :


/*  C++ Program to find Factorial of a Number using for loop  */

#include<iostream>
using namespace std;

int main()
{
    int i, n, fact=1;

    cout<<"Enter any positive number :: ";
    cin>>n;

    for(i=1;i<=n;i++)
    {
        fact=fact*i;
    }
    cout<<"\nFactorial of Number [ "<<n<<"! ] is :: "<<fact<<"\n";

    return 0;
}

Output : :


/*  C++ Program to find Factorial of a Number using for loop */

Enter any positive number :: 6

Factorial of Number [ 6! ] is :: 720

Process returned 0

Factorial of a Number using recursion


Here is source code of the C++ Program to find Factorial of a Number using Recursion. The C++ program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.


SOURCE CODE : :


/*  C++ Program to find Factorial of a Number using Recursion  */

#include<iostream>
using namespace std;

int fact(int a);

int main()
{
    int fact(int);
    int f, n;

    cout<<"Enter any positive number :: ";
    cin>>n;

    f=fact(n);
    cout<<"\nFactorial of Number [ "<<n<<"! ] is :: "<<f<<"\n";

   return 0;
}

int fact(int a)
{
    if(a==1)
    {
       return(1);
    }
    else
    {
        return(a*fact(a-1));
    }
}

Output : :


/*  C++ Program to find Factorial of a Number using Recursion  */

Enter any positive number :: 7

Factorial of Number [ 7! ] is :: 5040

Process returned 0

Above is the source code for C++ Program to find Factorial of a Number using For Loop and Recursion which is successfully compiled and run on Windows System.The Output of the program is shown above .
