In this exercise, you modify the Professor Schneider application from Exercise 10. Use Windows to make a copy of the Schneider Solution folder. Rename the copy Schneider Solution-TwoDim. Open the Schneider Solution.sln file contained in the Schneider Solution-TwoDim folder. Change the two parallel arrays to a two-dimensional array named strGradeInfo, and then make the appropriate modifications to the btnDisplay_Click procedures code. Save the solution and then start and test the application.

In this exercise, you code the Professor Schneider application, which displays a grade based on the number of points entered by the user. The number of points should always be less than or equal to 500. The grading scale is shown in Figure 8-48. Open the Schneider Solution.sln file contained in the VB2017\Chap08\Schneider Solution folder. Store the minimum points and grades in two parallel one-dimensional arrays named intMins and strGrades. The btnDisplay_Click procedure should use the number of points entered by the user to search the intMins array and then display the corresponding grade from the strGrades array. If the user enters a number that is greater than 500, the procedure should display an appropriate message and then display N/A as the grade. Code the application. Save the solution and then start and test the application.
