# Write a program in c to calculate factorial of a number using function

Recursion Recursion means "defining a problem in terms of itself". Set Session Attribute Calculate factorial Using Recursion After going through this example you will be understand how you can calculate the factorial by using recursion in jsp.

After going through this example you will be understand how you can calculate the factorial by using recursion in jsp.

## Write a C# program to create a recursive function to find the factorial of a given number

Calculate factorial Using Recursion After going through this example you will be understand how you can calculate the factorial by using recursion in jsp. To make a program on factorial, firstly it must be clear what is recursion. In a simple language we can define recursion as a programming technique in which a function may call itself.

The key to solving recursively is to imagine that your method does what it says. To make a program on factorial by using recursion in jsp we are going to design a html page named calFactorial.

Only after that the value of the number can be calculated. Now define the method named factorial with return type of int, it will take one input whose factorial has to be calculated. We have defined this method inside the declaration directive.

## C Program For Factorial Of A Number Using For Loop - Coding Compiler

If the input number is more than 1 then the factorial will be calculated by using recursion. The output will be displayed to you by using the out implicit object of jsp, out object is responsible for writing the content on the jsp page.

In this program we have used following directives and implicit objects. The main logic of the program has to be written here. This is used for declaring variables and methods. Whatever we define in a declaration directive will be applicable in the whole page. It is one of the frequenly used implicit object.

It means that this object is applicable until the request object is present. This implicit object is used to write the content on the browser. The code of the html page is given below.Now, if we want to calculate a custom-made formula including factorial operations, we can create and optimize a function for that specific purpose.

Let’s say that we need to calculate without using the Matlab factorial function. Write an iterative O(Log y) function for pow(x, y) Modular Exponentiation (Power in Modular Arithmetic) If you like GeeksforGeeks and would like to contribute, you can also write an article using iridis-photo-restoration.com or mail your article to [email protected] These while loops will calculate the Factorial of a number.. In mathematics, the factorial of a number (that cannot be negative and must be an integer) n, denoted by n!, is the product of all positive integers less than or equal to n. Factorial program in C programming language: Three methods to find factorial, using a for loop, using recursion and by creating a function.

Factorial is represented using '!', so five factorial will be written as (5!), n factorial as (n!).
