C++ const method on non const pointer member

Question

I was wondering how protect a non const pointer member from an object throught a const method. For example:

class B{
    public:
        B(){
            thi         


        

Answer 1

If you change the member of A from

    B* b;

to

    B b;

then you will get the expected behavior.

class A{
    public:
        A() : b() {}

        void changeMemberFromConstMethod() const{
            this->b.setVal(); // This will produce a compiler error. 
        }
    private:
        B b;
}
