Inherit from const class

Question

I would like to inherit from a class with the const specifier like this:

class Property
{
    int get() const;
    void set(int a);
};

class Co         


        

Answer 1

I have a trick, not a clean solution.

class ConstChild : private Property
{
    operator const Property () { return *this; }
};

then

ConstChild cc;
cc.set(10); // ERROR
cc().get();
