Protected Inheritance

[benp84]

Why can't this derived class access protected data from its base class?

class A {
protected:
	int n;
};

class B: public A {
	int f(B* b) {
		return n + b->n;
	}
};

Edit: wait a second, this should work.
Is this really the exact code you're trying to compile? Are you perhaps trying to access n using a pointer to A?

OK thx.

b->n looks like trying to access a private member.
So even if the object is of our class type, it should still be illegal?

Edit: never mind.
