ModMove | Move/Resize windows using modifiers and the mouse

I'm sorry if I am asking something that has been asked many times before here. I am very new to C++. I want to know how to make a derived class inherit copies of the private attributes of its base class. Either that, or be able to modify them via public methods, such as getters and setters, from the base class.

Essentially, I have a Person class and it inherits from the Creature class. I want Person type objects to have attributes like in the Creature class. I want to private attributes in the Creature class to stay private because I was taught that only class functions should be public, not class variables. However, I can't seem to call the Creature class's public methods in a function, and the Person class doesn't seem to inherit them or copies thereof.

The reason I am refusing to simply make the private attributes public is because I want to learn proper programming techniques. I am not sure if this situation is an exception to the rule or not.

I have cpp files that handle the implementation. Hopefully, this will be enough to help you answer my question. My Base Class:
