Question

Problem Specification:
Write a C++ program to calculate student’s GPA for the semester in your class. For each student,
the program should accept a student’s name, ID number and the number of courses he/she is
taking, then for each course the following data is needed
 the course number a string e.g. BU 101
 course credits “an integer”
 grade received for the course “a character”.
The program should display each student’s information and their courses information. It should
also display the GPA for the semester. The scale for each grade would be

 A 4 points
 B 3 points
 C 2 points
 D 1 points
 F 0 points

Print out the complete information including the GPA. You may read the data from a file and send your
output to a file.
Note that the students are not taking the same number of courses; also note that the number of credits may
vary for each of the courses.

Requirements:
 Define a class for course information, private data members are course number, number of
credits, and the grade earned for the course.
 Define another class for the student, private data members are the student name, ID number,
number of courses, GPA, and a vector of course information defined above.
 you may write one or multiple mutator functions to read the data for each class
 Each class is defined in a header file and implemented in another.
 Your client file, defines an array of student objects. To test your program, make the array size
2 or 3 student objects, with various number of courses, credits per course and grades.
 Output the report as specified above and shown below.
 Comment thoroughly and use specifications for every function.

Sample output:

&~&~&~&~&~&~&~&~&~&~&~&~

Grading criteria:
5 points Proper spacing, comments, and general program appearance.
20 points classes are defined properly and correctly.
5 points guards are used for every class.
10 points class diagrams are included.
10 points all accessor methods are constant and all parameters are constant reference.
10 points an implementation file for each class includes all member functions for the class.
10 points every function has full specifications.
5 points an array of objects is defined in the client.
10 points a vector of course info is defined as a data member in the student’s class.
10 points Program design and implementation are as specified.
5 points test data, result of run, diagrams, and source are submitted.

Submission Details:

Submit a print-out of:
 The source file
 A copy of your input data
 A copy of the output file.
