say you're managing a stock portfolio... of class Portfolio, and it is to contain a linked list of several of class Stock... or more like... Portfolio is supposed to contain a Node structure to contain each Stock and the pointer to the head list... is this how it is done?

 c++ Syntax (Toggle Plain Text) 
class Portfolio 
{ 
   struct Node 
   { 
      Stock whateverstock;
      Stock* head;
   }
}
class Portfolio 
{ 
   struct Node 
   { 
      Stock whateverstock;
      Stock* head;
   }
}

Does this node actually contain a full Stock object instance? Or does a node within the Portfolio class only contain the pointer? There was some template for doing things like this... but I forget how that's done... let me attempt a more generic example...

 c++ Syntax (Toggle Plain Text) 
class Whatever
{
   struct Node
   {
       SomeOtherObject  thatObject;
       SomeOtherObject* headptr;
   }
}
class Whatever
{
   struct Node
   {
       SomeOtherObject  thatObject;
       SomeOtherObject* headptr;
   }
}

Note that NO inheritance is used here. Portfolio does not inherit anything from Stock or vice versa.
