Do Sub-Classes Really Inherit Private Member Variables?

Question

Basically as far as I know, when you create a base class with a public, protected, and private section and variables/functions in each the public and protected sections will

Answer 1

myObject and yourObject are two different objects! Why should they share anything?

Think about it that way: Forget about inheritance and suppose you have a class Person with private int age; and public void setAge (int age) {...}. You then instantiate two objects:

Person bob;
Person bill;
bob.setAge(35);

Would you expect Bill to be 35 now, too? You wouldn't, right? Similarly, your myObject doesn't share its data with yourObject.

In response to your comment:

The class yourClass inherits from myClass. That means that both yourObject and myObject have their own myVariable, the latter obviously by definition, the former inherited from myClass.
