Explain how to Inherit base class in Public, Private and Protected Mode code example

Example: 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
}
