Question

I am writing a a linked list and I have an Iterator class within my List class.
I want to overload the = operator but I don’t know the correct syntax to start it.

This is what I have in my code

class List{
   //member stuff
   class Iterator{
       private: Node* current;
       public: Iterator& operator=(const Iterator& right);
       }
 }

I am trying this but I am unsure whether this is correct or not.

List::Iterator::operator=(const Iterator& right){
 //stuff
}

Can anyone clarify?

Answer 1

To clarify, your thoughts are correct, but you forgot to have a return type in your function declaration:

List::Iterator::operator=(const Iterator& right){
 //stuff
}

needs to be

List::Iterator& List::Iterator::operator=(const Iterator& right){
 //stuff
}
