Question

I was wondering how you would call a getter function from another class in another class. For example what I have right now is not working

class A{
public:
    friend class B;
std::string getfirst(){ return b.getfirst();}
private:
    B b;
};

class B{
public:
    std::string getfirst(){
        return first_;

    }
private:
    std::string first_;

};

How would I fix this so that I can call B’s getfirst function?

Answer 1

You do not need friendship.

What about?

class B {
public:
    std::string get_first() const { return first_; }
private:
    std::string first_;
};

class A {
public:
    std::string get_first() const { return b.get_first(); }
private:
    B b;
};

Now, class B has a getter for its first and class A has getter that delegates to b member variable.
