Help With Class Interactivity!

[confundido]

I'm trying to write a program that deals with information from two separate classes. There's an emphasis on restricting access to data between the two, and instead relying on functions to bounce back and forth between the two.

The current program is designed to allow the user to store practice questions into the system and eventually write them to an external file.

I have everything working thus far, however I'm running into an issue when I try to fix the chronology of questions when you delete one.

I.e. if you have 5 questions in the system and you delete question 3, I wanted to have questions number 4 and 5 incremented up into that position.

I had this working fine when not using multiple classes, but a single structure, I just can't import that code to a way that works and wanted to get some help.

I'm also not quite to the point of using linked lists, and restricted from using the string class.

Let me know if you are able to help, or have any solutions in general to the setup I have with the classes

#include <iostream>
#include <cstring>

#include <ctime>

using namespace std;

        void clearTemp();
        void storeTemp(int & counter);
        void clearSave(int & counter, int delChoice);
        void displayTemp();
