his program we are going to find the factorial * of a user entered number. * A factorial is a multiplication of all numbers less than * or equal to that number. * factorial of x = x * (x-1) * (x-2) * (x-3) * ... *2 * 1 *
In JAVA:
public class 4A {
/**
* In this program we are going to find the factorial
* of a user entered number.
* A factorial is a multiplication of all numbers less than
* or equal to that number.
* factorial of x = x * (x-1) * (x-2) * (x-3) * ... *2 * 1
*
* For example, factorial of 4 = 4 * 3 * 2 * 1 = 24
* */
public static void main(String[] args) {
// First we need to create two variables
// First will store the user entered number whose factorial we will count
// Second will store the computed factorial value
/* Now prompt the user to enter a number Remember to include the necessary library
and the object required to read from the keyboard*/
// Think what loop could you use in this case (while, do-while, for)
// How would you start?
// What would the loop body have?
// Ensure that you are storing the calculated values in the right variables
// Once you come out of the loop, you should have the final factorial value
// Print out the factorial value outside the loop
