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. Logic to find the factorial of a number using recursion: get the input from the user, by using the entered value the fact() is called, the n 1 value is passed to fact() from the function,.
Declare recursive function to find factorial of a number. first let us give a meaningful name to our function, say fact(). the factorial function accepts an integer input whose factorial is to be calculated. hence the function declaration should look like fact(int num);. the function returns factorial as an integer value. The factorial of a number is the product of all integers between 1 and itself. there are four ways to find a factorial of a given number, by using for loop, while loop, recursion, or by creating a function on a range from 1 to x (user entered number). remember that the end value must be the number entered by the user 1. To calculate the factorial of a number using recursion, we will break it down into smaller numbers recursively until we reach 0. as soon as the recursive function reaches 0, we will return 1 because the factorial of 0 is 1. here is the algorithm we will use: factorial(n) = n*factorial(n 1); factorial(0) = 1; see implementation in the following. In this tutorial, we will learn how to find the factorial of a number in c programming language using recursion. recursion means the function will call itself. for example, the factorial of 5 is 5 * 4 * 3 * 2 * 1. we will call send this number to a function. it will call itself with 5 1 =4 and multiply it with 5. the inner function again call itself etc. it will be more meaningful if i will.

C program to find factorial of a number using recursion. this program allows you to enter any integer value. user entered value will be passed to the function we created. within this user defined function, this c program finds the factorial of a number recursively. please refer to the recursion in c article before this example. it will help you. In this guide, we will write a c program to find factorial of a number using recursion. recursion is a process in which a function calls itself in order to solve smaller instances of the same problem. this process continues until the smaller instance reaches a base case, at this post the recursion process stops and produces the result.
