LinkedList Part
<p>I think I might have done something right, headByRating and headByName both refer to the same address.</p>

<p>I have been drawing diagras working all day trying new things etc, and i havent really made any progress.</p>

<p>I have two list pointers, headByRating and headByName.
and two node pointers nextByName and nextByRating.</p>

<p>Somehow I need to be able to sort this stuff by its name and rating.
I've been thinking that I do that by each of the ptrs' address'.</p>

<p>2 statements as an example that I have been trying to sort:</p>

<pre>
//main.cpp

list *wineries = new list();
wineries->insert(winery("Lopez Island Vinyard", "San Juan Islands", 7, 95));
wineries->insert(winery("Gallo", "Napa Valley", 200, 25));
</pre>

<p>the winery ctor is fine everything is allocated and into the object at this point:</p>

<pre>
//list.cpp
void list::insert( const winery& winery )
{
         list *listPtr  = new list(); // havent really used the list obj. yet.

    node *current = new node( winery ); // winery is now a node.
    node *temp   = current;     // temp knows about the nodes address.

    while ( temp->nextByName != NULL )
    {
                 // check for null and reassign 
     temp = temp->nextByName;
    }
    node *new_node = new node( winery ); // creating a new node.
    new_node->item = winery; 
    new_node->nextByName   = new_node;
    new_node->nextByRating = new_node;
}
</pre>

<pre>
// list.h
struct node
{
    winery  item;
    node *  nextByName;
    node *  nextByRating;
};

class list
{
    ...
private:
    node * headByName;
    node * headByRating;
};
</pre>

<p>What is a good approach to this? I dont think im doing this right. </p>
