In this exercise, you code an application that displays a grade based on the number of
points entered by the user. The grading scale is shown in Figure 9-44. Open the VB2015\
Chap09\Perez Solution\Perez Solution (Perez Solution.sln) file. The user will enter the total
possible points in the Possible points box. The btnCreate_Click procedure should store
the minimum number of points and the grades in two parallel one-dimensional arrays.
The btnDisplay_Click procedure should display the grade corresponding to the number of
points entered in the Earned points box. Save the solution and then start the application.
Enter 300 in the Possible points box, and then click the Create Grading Scale button. Enter
185 in the Earned points box, and then click the Display Grade button. The letter D should
appear in the Grade box. Next, enter 275 in the Earned points box, and then click the
Display Grade button. The letter B should appear in the Grade box. Enter 500 in the Possible
points box, and then click the Create Grading Scale button. Enter 400 in the Earned points
box, and then click the Display Grade button. The letter C should appear in the Grade box.
Test the application using different values for the possible and earned points
