Microsoft Visual C#:

Create and test a Windows Forms application that implements a GUI-based solution to Programming Exercise 6-7 from p. 261 of the text. The Nimble Fingers Typing School assigns grades based on words typed per minute, as shown in the table below.

Create a GUI application that allows a user to enter a students number of words typed. Make sure the user's input is valid, otherwise prompt them to correct their mistake using a MessageBox. The output is the letter grade earned by the student. The design of the application's interface is up to you. You must use parallel arrays and range matching (not simply a series of if/else if statements).
