Program To Calculate Factorial In Php
PHP Recursive Function Example: Factorial Numbers. I spun up the simplest example I could think of to illustrate a recursive function to a PHP beginner the other day. Factorial Program in C++ - Factorial of any number is the product of an integer and all the integers below it for example factorial of 4 is 4! = 4 * 3 * 2 * 1 = 24. Write a program to print factorial of a number in PHP. In this tutorial, we are going to write a program to print factorial of a number using recursion as well as.
Prolog Program To Calculate Factorial Of N
Factorial of a number is defined as the product of the number and all of the numbers small than it. So if you take the number 4 the factorial of that number is 24 or 1 x 2 x 3 x 4.
Algorithm To Calculate Factorial
Factorials are useful for a number of applications, for example when working out how many times a set of objects can be combined in different ways. Use the following PHP function to work out the factorial of any given number. The first thing it does it make sure that the number is greater than 1 because the factorial of the number 1 is 1.
