Linked List with Iterator

I'm trying to write a linked list for my Smart Pointer class and i have no problem writing one by itself for a specific class such as int and it will even store my SmartPtr<int> if its made as a linkedlist<long int> because i save a reference to them but it's when i get to classes i can't do anything with. My question is is there anyway to get a reference for a built class and possibly store it as an int.

It is certainly possible to convert a reference to an object (not a class) to an integer, but this is undesirable (because it breaks all the type checking).

The reason for using templates is to avoid this kind of thing. Wouldn't you just declare something like "linkedlist<SmartPtr<int> >"?

Yeah well that would work for the ints but i have smart pointers pointing to classes iv made aswell i can get it to work for ints chars etc. but not my classes

I think you are saying that your code fails for the case "linkedlist<SmartPtr<MyClass> >"?

It is worth reading more on templates, since some of the concepts involved are not trivial. The STL library already has linked lists, and it can handle most classes (as long as they have appropriate constructors and comparison operators).

If you have specific issues, perhaps you could provide code fragments so that others can suggest improvements and ways of dealing with errors.
