Question

You will create a class to store information about a student�s courses and calculate their GPA. Your GPA is based on the class credits and your grade. Each letter grade is assigned a point value:

A = 4 points

B = 3 points

C = 2 points

D = 1 point

An A in a 3 unit class is equivalent to 12 grade points (4 for the A times 3 unit class)

A C in a 4 unit class is equivalent to 8 grade points (2 for the C times 4 unit class)

This is a total of 20 grade points. Your GPA is calculated by dividing the total grade points by the total class credits, so in this case:

20 grade points / 7 credits = 2.85 GPA

Create a class called StudentInfo that represents the following information (private data) about a student:

Student name

Total grade points

Total credits

Create the following public member functions.

(Note that the program may not require all functions to be used, but they should all exist for a complete class.)

Default constructor to initialize grade points and credits

setName                 Set value for name

getName                 Returns the name

addClass                 receives as input the class units and grade, updates grade points and credits appropriately

getGPA                   Calculates and returns the GPA

displayStudent          Displays all info about studetn

Note that ONLY student name will be �set� from the outside. The grade points and credits will be modified with the method AddClass which takes as parameters the number of units for the class and the grade awarded. This method then adds the appropriate grade points to the total, and also adds the credits to the total.

You will need a method to �get� the GPA which will calculate and return it.

Write a program to test the class as shown below. You should ask for the student�s name, then allow them to add multiple classes. When done, display the GPA.

Note that it will be easier to use String for the grade rather than char since Scanner does not have a method to easily return a char.

Sample Output (note formatting):

Enter Student name: Joe Smith

Enter class credits: 3

Enter letter grade: A

Another class? y

Enter class credits: 4

Enter letter grade: C

Another class? n

Joe Smith, your GPA is 2.86

Another employee? (Y/N): n
