# Inheritance

public inheritance makes public members of the base class public in the derived class, and the protected members of the base class remain protected in the derived class.
protected inheritance makes the public and protected members of the base class protected in the derived class.
private inheritance makes the public and protected members of the base class private in the derived class.

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
}
