GETTING HELP: You may ask another student for help, but you must not copy their code. Failure of the course will result for the person giving code and the person receiving code. I can get limited help from other students. For additional help, I need to see Dr. Scanlan, his assistant, or the tutoring center.

Programming Assignment 05 Due: May 1, 2014 30 POINTS: Purpose: You are to take program 4 and modify it so that it matches these requirements: 1. This program is EXACTLY like program 04 EXCEPT you will eliminate these modules: (1) ”Calculate Letter Grade Without + -”, and (2) “Calculate Letter Grade With + -”. Instead of these two modules, you will write and use two classes that perform these same functions. 2. See the class diagrams on the next slides for (1) the names of the two classes, (2) the properties in the classes and (3) the single method in each of these two classes. 3. You are to send the percentage score as a property value to the class and receive back the letter grade. You must use a FUNCTION procedure for the single method in each of the two classes. 4. You must use the names supplied in the class diagram on the next slide. 5. The grade cutoffs are CONSTANTS within the class. Thus, the user cannot SET these cutoffs, but the user will be able to GET them. These cutoffs are percentage cutoffs such as 90%, 80%, 70%, 60%, etc. and 97%, 93%, 90%, 87%, 83%, 80%, etc. 6. You must create the class in the new-project dialog box in the IDE. This class will be a file within your Solution file. The names of the files must be the class names: “clsLetterGradeWOPlusMinus” and “clsLetterGradeWPlusMinus”. 7. Don’t forget to use internal documentation within these classes. 8. The following slides will give you more information on what to do. 9. You are to use #Region…#End Region on all modules of code. (See next slide.) 10. You must use Option Strict ON 11. ASK QUESTIONS IN CLASS IF YOU DO NOT UNDERSTAND SOMETHING. Necessary prerequisites 1. Chapters 1, 2, 3, 4, 5,6, 12 2. Notes: Notes Chapters 1,2,3,4,6,12 5. GroupBoxes 6. Subtraction and division 7. ByVal and ByRef 8. Try/Catch 9. Classes: properties and methods 10. Message box 11. Hierarchy chart. 12. Class Lectures

IMPORTANT: Notice how nicely the regions organize your code. Programming Assignment 05 Use the names given below for your Regions How to define a region: #Region “MODULE’S FUNCTION” ‘Place your code here. #End Region IMPORTANT: Notice how nicely the regions organize your code.

Programming Assignment 05 This diagram of the class is called a CLASS DIAGRAM. Class name clsLetterGradeWOPlusMinus PercentageScore A_Cutoff B_Cutoff C_Cutoff D_Cutoff ComputeLetterGrade Properties Note: THE NAME OF THIS METHOD HAS BEEN CHANGED FROM ComputeGrade TO ComputeLetterGrade. Change your code! (Reason: The new name is a better name.) Method

Programming Assignment 05 Eliminate this module and add the module below. Call the module below from the “GradesWithout+ -” module. Sub CalculateLetterGradeWithoutPlusAndMinus(ByVal decPercentageScore As Decimal, _ ByRef strLetterGrade As String) Dim objLetterGradeWOPlusMinus As New clsLetterGradeWOPlusMinus ‘ PLACE YOUR CODE HERE. ‘ THIS CODE WILL USE YOUR CLASS TO CALCULATE THE LETTER GRADE. ‘ THIS MODULE HAS NO CASE LOGIC IN IT. THE CASE LOGIC IS NOW IN YOUR CLASS. ‘ Use decPercentageScore to SET the PercentageScore property. ‘ Use the ComputeLetterGrade method to return the letter grade from the class. End Sub
