C program for calculating factorial using recursion

Example to find factorial of a non-negative integer entered by the user using recursion. This program takes a positive integer from user and calculates the factorial of that number.

Suppose, user enters 6 then,. Visit this page to learn, how you can use loops to calculate factorial. In the above program, suppose the user inputs a number 6.

The number is passed to the factorial function. For this, the number 5 is passed again to the factorial function. And, 4 is passed to the factorial function. Course Index Explore Programiz. Popular Examples Create a simple calculator. Check prime number. Print the Fibonacci sequence. Check if a number is palindrome or not.

Program to multiply matrix. And the factorial of 0 is 1. You will learn to find the factorial of a number using recursion in this example. Visit this page to learn how you can find the factorial of a number using a loop. Initially, multiplyNumbers is called from main with 6 passed as an argument. Then, 5 is passed to multiplyNumbers from the same function recursive call. In each recursive call, the value of argument n is decreased by 1.

When the value of n is less than 1, there is no recursive call and the factorial is returned ultimately to the main function. Course Index Explore Programiz. Popular Tutorials Data Types in C.
