Program Specification

When the program first launches, there is a menu which allows the user to select one of the following five options: 

1.) Add a course

 2.) Add a student 

3.) Add a result 

4.) View results 

5.) Quit

The functionality of these options is as follows:  

1.) When users add a course they provide a course code and a course name which is stored in some manner of array or list. 

2.) When a user adds a student they provide a student id and a name which is stored in some manner of array or list. 

3.) When a user adds a result they provide a course code, a student id, and a final score out of 100 which again is stored in some manner of array or list. To successfully store the result: 

              a. The course code must be a course which has been created,

              b. The student id must be of a student who has been created, and

              c. The score must be within 0.0 to 100.0 inclusive and accept invalid input without crashing. 

4.) When a user views results they have the option to:  

              a. View course results, or

              b. View student results.

If the user opts to show course results then they are prompted to enter a course code - and then the results of each student enrolled in that course are displayed.

If the user opts to show student results then they are prompted to enter a student id - and then the final score for each course they are enrolled in and an average student score is shown (which is the sum of each of the students’ scores for each course divided by the number of courses they are enrolled in).

5.) When a user chooses to quit then the program terminates with a goodbye message.  

Each implementation of your project (in each of the four languages you choose) should aim to closely match the setup and structure of the program as shown in the example output on the following pages. 

You may wish create separate Course and Student classes as part of your implementations, but you do not have to. 

You may also wish to add code to pre-create a number of students and courses to avoid the need to type in these details over and over when testing your code. If you do so, please remove these pre-defined Students and Courses before submitting your assignment.
