Subclasses

Are there such a thing?

I am wanting to create a class "car" that contains many classes. Could I do this, if so how.
I would like to address it like car.engine.size()

Yep, something like -

class car
{
public:
	class engine
	{
	public:
		int hp;
		int cc;
    }the_engine;
	//more stuff

};

int main()
{

	car beast;
	beast.the_engine.hp=15000;

	return 0;	
}

Thanks, I thought it might be something like that

i don't think so sorenson, it'd be more like this:

class engine
{
 public:
 int hp, cc /*etc.*/;
}

class car
{
 public:
 engine theEngine;
 //other stuff.
}

what you did may work, but i prefer doing it this way.

Of course it'll work. If engines are only used within cars then I see no reason not to do what I have done, as long as engine is a simple class and they are only required by cars, it would be possible to prevent orphaned engines being created.
