C Program to find the Factorial of a Number using Recursion

In this video you will learn to write a C Program to find the factorial of a number using Recursion ( Recursive Method ).

The factorial of a positive integer n, which is denoted as n!, is the product of all positive integers less than or equal to n.

That is n! = n * (n-1)*(n-2)*....*3*2*1

So 4! = 4 * 3 * 2 * 1 which is equal to 24.

Factorial for the numbers 0 and 1 is 1. That is 0! = 1 and 1! = 1. For negative numbers factorial value doesn't exists.

C Program to Find the Factorial of a number using Iterative method ( For Loop ).
