Gradebook Program help

[crashband]

I have an assignment for class and could use some help. I will post the problem below I just need advice on how I would store all the data. Also how would I access it after I store it. Side Note we are not allowed to use structures or objects.


ASSIGNMENT

For the purposes of this gradebook you should first provide a menu with the following options

Add a new course
Add a new student to a course
Add grades for a student in a course
Print a list of all grades for a student in a course
Print a list of all students in a course
Compute the average for a student in a course
Compute the average for a course
Store Gradebook (to a disk file)
Load Gradebook (from a disk file)

Each of these menu items should correspond to a function you will write.

For the basic program each student will be represented by an ID number
And each course by a course number
Grades will be whole numbers only (no fractional part)
As indicated in the menu you will need to store and load using a disk file so that the data is retained.
Here are so limiting values to help you in defining your data structures:
Maximum Number of students (total) 100
Max number of courses 25
Max number of courses per student 4
Max number of grades per student per course 10

Then what are you allowed to use?

You need to show your code for what you've tried.

I guess we can use anything else besides structures or objects. The only code I have now is the prototypes and the menu. I just need guidance on how i would store the course id and student id and then be able to look it up.

I guess it can be done using single and multi-dimensional arrays instead of structures, but it gets more complicated this way, so it's kinda a waste of effort imho.

Btw, the assignment's wording seems to be using the term "data structures"...

although I think it means arrays (since data structures are prohibited as you say).

How would I be able to match up the student with their grades by using arrays?

How would I be able to match up the student with their grades by using arrays?

This is called "Parallel Arrays", and is generally taught just before structs, in a programming class.

It works for 2 record items, per record - but uses arrays instead of records (structs).

i.e.:

Array1   Array2        Index Number  Array1 is a char array, Array2 is an int array.
Name    Test Score
John        88             0
Ian         91             1
Janice      89             2
Linda       84             3
Bob         78             4

The common factor here is the index number. As long as "John" has the same index number: array1[0] as array2[0], (and all the others keep their same index number also), then you can go ahead and work with the data, with confidence - even sort the list by names, or by test score, whatever you like.

Just be sure whenever you change the index number for either a name, or a test score, that you also change the associated other array data.

There is nothing wrong with using multi-dimensional arrays, IMO, for this problem. The big drawback is that the amount of "records" you can store has a limit defined by the size of the array you declare.
