Factorial recursion is a method in which a function directly or indirectly calls itself. In mathematics, Factorial means the product of all the positive integers from 1 to that number. An exclamation mark is used after the integer to show that it's a factorial. For example, factorial eight is 8!
Oct 12, 2023 · Factorial can be calculated using the following recursive formula. n! = n * (n – 1)! n! = 1 if n = 0 or n = 1.
In this C programming example, you will learn to find the factorial of a non-negative integer entered by the user using recursion.
