Adding variables and functions to class through program

Question

So i am trying to code a program to sort and list some data. I use a vector with my class so every entry got its own object. But i realized i may want to add more tags/categorys to every entry and to store this new data i need a new variables or new functions in my class. How can i add something like variables and Getter + Setter to my class without having to know which new categorys i am going to add?

What I have tried:

I tried to do something with the constructor but i think thats not right. I used an array instead of vector.

I think you should do some design wor with UML to clarify what you want to code. Here is a tutorial. An easy solution is also to draw it at paper - best with a pencil.

Dont knowing the type of the variables is bad style.

You can do such stuff by adding a dictionary which has a key (your var) and a value (the value).

A common design pattern is interface. You define some compatible functions but not the class.

An advice from a seasoned developer: if you dont know WHAT to implement your work is for the trashcan. ;-)
