C++ Inheritance

Given

class A {
    public:
        int x;
    protected:
        int y;
    private:
        int z;
}

The accessibility of A's member variables from a derived class B is as follows:

	B::x	B::y	B::z
class B : public A	public	protected	N/A
class B : protected A	protected	protected	N/A
class B : private A	private	private	N/A
