Sorry for the bad title, but I couldn't think of a better one.
I'm having a class A and a class B which is kind of a sub class of A, like so:
(Is there actually a correct name for it? Isn't "sub class" reserved for inheritance?)
class A { int i = 0; class...

Additionally, B does not hold an instance of A, so:
class A { public class B { public A Parent; public B(A parent) { this.Parent = parent; } } }

This might make it clearer
class Bar.
Foo::getName() isn't valid outside the function because than completely override the behaviour of the base class, e.g.

I need to style an element that has both class "a" and class "b". How do I do it?
The order the classes appear in the html might vary.

Say you have two classes, A and B. Is it possible to instantiate both classes once and then let class B call methods in class A, and vice versa?
It can be done using double colon (::) ... ... but then the method becomes static - is that a disadvantage...

The CSS class is the modern method....
The <b> tag is from older versions of HTML as such .
That approach allows me to separate the CSS class rather than the actual html markup.

In the interest of reusing some existing code that was defined as an instance method of a different class, I was tying to do something like the following:

I'm using a framework which defines and uses 'ClassA', a subclass of NSObject. I would like to add some variables and functionality so naturally I created 'ClassB', a subclass of 'ClassA'

Every car.
Think of it this way: you have a Car (the parent class) and a FourDoorSedan (the subclass).

You can't just cast a super class to it's subclass.

Since you have declared struct PImpl in the private part of CDataHolder class, only friends section or even better before the CDataHolder class....
