Using a class within it's own declaration

ok, so my problem is this. I need to copy a custom made list and the function has to be a private member of my list-class. looks like this atm:

private:
struct List_Node* head_;
List* copy(List* list);

looks like crap i know, but i have been told to do it that way. getting the compilation error:

error: `List* List::copy(List*)' is private

is there some way to go around this problem or am i understanding my directions wrong?

Solution

  • You need to call the function from within another member function which is public.

    You cannot call private member functions from outside the class. The error suggests you are doing that.
