Question

I’m trying to stop class B from accessing DoSomething(Class Y) function and only access DoSomething(Class X) . How can I do that in C++ ?.

Class A {
    public:
        void DoSomething(Class Y);
}

Class B: public A { 
    public:
        void DoSomething(Class X);   
}

Answer 1

You can make A::DoSomething(Class Y) private, and that’s about the only way you can go about it.

Also, you’re not overriding here, but hiding. Still, in class (yes, it’s lower-case, not upper-case) B, you can still call A::DoSomething(). private‘s the only way to deny access.
