copied!<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>
