The factorial of an integer can be found using a recursive program or an iterative program. A for loop can be used to find the factorial of a number using an iterative program. This is demonstrated as follows.

Introduction to Factorial in R. A mathematical concept which is based on the idea of calculation of product of a number from one to the specified number, with multiplication working in reverse order i.e. starting from the number to one, and is common in permutations and combinations and probability theory, which can be implemented very effectively through R programming either through user.

Here you will get python program to find factorial of number using for and while loop. Factorial of a number is calculated by multiplying it with all the numbers below it starting from 1. For example factorial of 4 is 24 (1 x 2 x 3 x 4). Below program takes a number from user as an input and find its factorial.

There is a builtin function in R Programming to calculate factorial, factorial() you may use that to find factorial, this function here is for learning how to write functions, use for loop, if else and if else if else structures etc. Example 2: Find factorial of a number with while loop In this example you will find factorial with while loop in R.

Write a PHP script to calculate and print the factorial of a number using a for loop Introduction. PHP is a server scripting language, and It is a powerful tool for making interactive and dynamic Web-pages. I have used WampServer 2.2 for following example.

Variables for program - int to store number, long int to store factorial because factorial value is higher than integer value. Now, input the number. Run a loop from num to 1 and multiply the numbers in a variable called fact. And the fact will be the factorial after executing the loop.

Note: The logic of the factorial program remains the same, but the execution differs. Now that you are clear with the logic, letâ€™s try to implement the factorial program in Java in another way i.e using while loop. Factorial program in Java using while loop. While loop in Java help your code to be executed repeatedly based on the condition.
