Thank you very much for you answer.

Also since you store books (which can be comic books), you really need polymorphism here, so std::vector<Book> should be std::vector<std::unique_ptr<Book>>.

I must split in two my doubts.
I think that makes all sense use only one "add function" to create the different type of products (different subClasses). I think that I was avoiding put it on design, because I don't know how to implement this kind of function.
I think that you're right about the Polymorphism in Book and ComicBook. I need to read more about the subject because I didn't get how it can be implemented.

Creating a conceptual problem was very useful. I figured out how important is the design fase, how important is study some subjects such as Composition or Polymorphism.
