In this exercise, you modify the application from Exercise 16. The modified application allows the user to display the number of students earning a score within a specific range.

Use Windows to make a copy of the Scores Solution folder. Rename the folder Modified Scores Solution. Open the Scores Solution (Scores Solution.sln) file contained in the Modified Scores Solution folder. Open the designer and Code Editor windows. Modify the btnDisplay control’s Click event procedure to prompt the user to enter both a minimum score and a maximum score. The procedure then should display (in a message box) the number of students who earned a score within that range. Save the solution and then start the application. Use the application to answer the following questions, and then close the Code Editor window and the solution:

How many students earned a score from 70 through 79?

How many students earned a score from 65 through 85?

How many students earned a score from 0 through 50?
