C Program to Find Factorial of a Number using While Loop

Factorial is a product of all positive numbers from 1 to n, here n is a number to find factorial.

Ex: 5! = 5*4*3*2*1

PROGRAM:

#include <stdio.h>
int main()
{
    int n,i,f;
    f=i=1;
    printf("Enter a Number to Find Factorial: ");
    scanf("%d",&n);
    while(i<=n)
    {
        f*=i;
        i++;
    }
    printf("The Factorial of %d is : %d",n,f);
    return 0;
}

 OUTPUT:

Enter a Number to Find Factorial: 5
The Factorial of 5 is : 120
