The key difference is that members in a struct default to public, in a class they default to private. You made all of the members of your class public so it shouldn't really matter. Your list handling needs some work though. In your code, start is a tree and current and temp are … Re: Classes and Linked Nodes 15 Years Ago by sleight Oh, maybe that's why I filled up the memory, I created duplicates and not pointers.

If linked list does not contain any elements nothing should be printed. If the list contains only 1 element then only that element should be printed. If the list contains only 2 elements then only those 2 elements should be printed.

So the struct cannot be accessed without the object of the class Is it necessary for you to have the struct inside the class ? There are 2 simpler options 1. Avoid the concept of class all together. Just use structs 2. Dont use struct inside the class.
