Check prime number. Print the Fibonacci sequence. Check if a number is palindrome or not. Program to multiply matrix. Reference Materials iostream. Find Sum of Natural Numbers using Recursion. Calculate Factorial of a Number Using Recursion.

Find G. D Using Recursion. This Program prompts user for entering any integer number, finds the factorial of input number and displays the output on screen. A factorial of a number x is defined as the product of x and all positive integers below x.

A factorial is product of all the number from 1 to the user specified number. And the factorial of 0 is 1. You will learn to find the factorial of a number using recursion and iterative methods in this example.

We will use a recursive user defined function to perform the task. To understand this example, you should have the knowledge of the following C programming topics:.

The factorial of a negative number doesn't exist. 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.
