This project uses a for loop nested within a while loop to calculate the factorial of a number.

Console

Operation

• The application prompts the user to enter an integer from 1 to 9.
• The application displays the factorial of the number entered by the user.
• The application prompts the user to continue.

Specifications

• The exclamation point is used to identify a factorial. For example, the factorial of the number n is denoted by n!. Here's 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.
• The grading criteria is as follows:

Enhancement

• Test the application and find the integer for the highest factorial that can be accurately calculated by this application. Then, modify the prompt so it prompts the user for a number from 1 to the highest integer that returns an accurate factorial calculation.
