Grading system
Grade point average (GPA)
Assuming a student enrolled in three courses and obtained the following results:
You will carry out OOD and OOP as follows:
. You must not use global variables.
. You must choose an appropriate data type (class) for each attribute.
. You must include appropriate properties and setters (or get and set methods).
. You may decide the appropriate parameter(s) for each method.
. You may include additional attributes and methods for each class.
. You must define a main function with helper functions to thoroughly test the functionalities of the program.
. You must include comments in the program.
