Chapter 5, Problem 12PP

Calculating the Factorial of a Number

In mathematics, the notation n! represents the factorial of the nonnegative integer n. The factorial of n is the product of all the nonnegative integers from 1 through n. For example,

  7! = 1 × 2 × 3 × 4 × 5 × 6 × 7 = 5,040

and

  4! = 1 × 2 × 3 × 4 = 24

Create an application that lets the user enter a nonnegative integer and then uses a loop to calculate the factorial of that number. Display the factorial in a label or a message box.
