Factorial Calculator

Create an application that calculates the factorial of the number entered by the user.

Console

Welcome to the Factorial Calculator

Enter an integer that's greater than 0 and less than 100: 3

The factorial of 3 is 6.

Continue? (y/n): y

Enter an integer that's greater than 0 and less than 100: 4

The factorial of 4 is 24.

Continue? (y/n): y

Enter an integer that's greater than 0 and less than 100: 9

The factorial of 9 is 362880.

Continue? (y/n): n

Specifications

The exclamation point is used to identify a factorial. For example, the factorial of the number n is denoted by n!. Heres how you calculate the factorial of the numbers 1 through 5:

1! = 1 which equals 1 2! = 1 * 2 which equals 2 3! = 1 * 2 * 3 which equals 6 4! = 1 * 2 * 3 * 4 which equals 24 5! = 1 * 2 * 3 * 4 * 5 which equals 120

Use a for loop to calculate the factorial.

Assume that the user will enter valid numeric data for the length and width.

Use the long type to store the factorial.

The application should continue only if the user enters y or Y to continue.

Input

An integer using a string prompt

Processing

Calculate the factorial of the entered number using the formula above.

Output
