Get instance of containing class

Question

Is it possible to access an object from a member object without passing and storing a reference? In the example below, could a given chair object get access to the house obj

Answer 1

There is no way to do that without the Chair having a reference to the House. From the point of view of the Chair, there is no relationship between it and a House. In fact, the Chair could belong to many Houses, or no Houses.

Answer 2

First off, is this an example of a real problem or just an example for learning purposes?

It's definitely not Chair's responsibility to check the house location. If you want to find all chairs in Miami you have to traverse the whole tree or give it a reference.
