public inheritance c++ for protected members code example

Example 1: inheritance protected in c++

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

class publicDerived: public base
{
	// x is public
	// y is protected
	// z is not accessible from publicDerived
};

class protectedDerived: protected base
{
	// x is protected
	// y is protected
	// z is not accessible from protectedDerived
};

class privateDerived: private base
{
	// x is private
	// y is private
	// z is not accessible from privateDerived
}

Example 2: c++ public inheritance not getting protected

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

class B : public A
{
    // x is public
    // y is protected
    // z is not accessible from B
};

class C : protected A
{
    // x is protected
    // y is protected
    // z is not accessible from C
};

class D : private A    // 'private' is default for classes
{
    // x is private
    // y is private
    // z is not accessible from D
};
