I have program that I don't know how to solve.

Question :

You are to develop a student record system tat makes use of the C++ structure and classes.
The record system is to be used to hold information about your assessment results for your current semester. This will allow you to keep track of your marks for each unit/module of study, display the total for each unit as you progress, as well as display the marks you need to obtain to pass the unit.

Unit/Module
1) EBEP2011- Principle of Electric Machine
ASSIGNMENT 1 -10%

You could design it this way:
-Create one DB class as the main, and a vector/struct, or a couple of them is internal containers to store the info(maybe each module to a vector/struct)
-Make those vectors/struct not inheritable by tagging them as "final"(C++11)
-For the derived class, they may have functions that use references to access the stored data.
