How to improve the logic for building complex structures?

Question

C++ / C#

Hello!

I have a course book where I need to implement a menu using commands. (such as in cmd for example)
But I can't build the structure of the application, its hierarchy!

Where can I pull it up, can find examples or something!
I tried to google, but I didn’t find anything normal.

I would like to say that I can make commands using ifs, and users using one class with a role field, but somehow I don’t really want to (plus each user has his own capabilities, etc.)

In OOP, this is solved using the Composite pattern

Without OOP, you can solve it with a recursive call.
