  class List
{

private:
         struct Node
         {
            int data;
            Node* next;

            Node(): next(NULL){} //define our own default constructor
            Node(int data): next(NULL), data(data){}
         };

typedef struct Node* NodeRef;

NodeRef head;
NodeRef tail;
NodeRef iterator; //points to one node at a time
int size;


I need to write one line of code to return the current element in the list. I think it's done like this?

int List::current()
{
   return iterator->data;
}

But it keeps giving me an error.
Can I get quick help please?
Thanks

What is the error that you are getting?

In main:

List L2;
lines to store values

As soon as my tests in main hits " cout << L2.current() << endl;"
I get a message that the project stopped working

This is means that is a runtime error, and I cannot be certain till I see complete code. It seems that the iterator is not initialised to a valid value before the call to current, from the posted code.
