C Program To Find Factorial of Number
Learn How To Find Factorial of Number in C Programming Language. It is important that we should know about How A For Loop Works before getting further with the C Program Code. This Code is described with an Explanation of Factorial Program in C Language. We have used Recursion method as well as the While and For Loops in the following Factorial Programs.
What is a Factorial of a Number?
A Factorial for a Non-Negative Integer is the Product of all the Positive Integers Less than or Equal to that Number. The Factorial Notation is used in Combinatorics, Permutations, Algebra and other Mathematical Analysis.
5! = 5 * 4 * 3 * 2 * 1 = 120
One interesting thing to note here is that the value of 0! = 1.
