Introduction Factorial:
In this article, We are going to discuss about the Factorial Program in C Language.
Factorial of a Number:
In mathematics, the factorial of a non-negative integer n, denoted by
n!
The Factorial is the product of all positive integers less than or equal to n.
For example, Factorial of 5 is
- 5! = 5*4*3*2*1 i.e 120
The value of 0! is 1, according to the convention for an empty product.
