Factorial Program Using Iteration in JavaScript Another way of writing a factorial program is by using iteration. In iteration, we use loops such as for, while, or do-while loops. Here also we will be checking

In the iterative approach, we use a loop like for or while to multiply the numbers in descending order to get the factorial. Example In this Java program, we find factorial of a number using a for loop. Open Compiler public class Example { public static void main(String[] args) { int...
In the following PHP program factorial of number 5 is calculated. This is a simple program using for loop. This for loop is iterated on the sequence of numbers starting from the number till 1 is reached. Code: <?php //example to calculate factorial of a number using simple for loop //...
I will admit this post was inspired by How would you write factorial(n) in java? So excuse me while I rant in code: I have a point to make at the bottom of this article. Now most people who write factorial in Java may start with something simple, like: p
* this loop is basically a reverse factorial calculation, where instead * of multiplying we are dividing. We start at i = 2 since i = 1 has * no impact division wise */ int i = 2; while (n % i == 0) { n = n / i; i++; } /*! * if n was the sum of a factorial ...
Input the Number: The program prompts the user to enter a number and reads the input using the "scanf()" function. This input is stored in the variable 'n'. Factorial Calculation (Using a Loop): A loop (such as a "for" loop or "while" loop) runs from 1 to the given number 'n...
returnnum*factorial(num-1);}}intmain(){intnum;// Declare variable to store the input numbercin>>num;// Take input from the user// Displaying the factorial of the input number using the factorial functioncout<<factorial(num)<<endl;return0;// Indicating successful completion of the program}...
Now let's see how we can calculate factorial using the while loop. Here's our modified function: function getFactorialWhileLoop(n) { let result = 1; while (n > 1) { result = result * n; n -= 1; } return result; } This is pretty similar to the for loop. Except for this ti...
Now let's see how we can calculate factorial using the while loop. Here's our modified method: public static int getFactorialWhileLoop(int n){ int result = 1; while (n > 1) { result = result * n; n -= 1; } return result; } This is pretty similar to the for loop. Except ...
