WebFeb 23, 2024 · A Doubly linked list is used in navigation systems or to represent a classic deck of cards. A Doubly linked list is a bidirectional linked list; i.e., you can traverse it from head to tail node or tail to head node. Unlike singly-linked lists, its node has an extra pointer that points at the last node. WebAdds the given node as next of the current node. // 2. Returns data of the current node. // 3. Return pointer of the next node. // 1. Add a Node at the Front. // 2. Add a node at the end.

Obviously None has no getPrev. What you actually want to do is get to the end of your list and first (and deal with it from there). WebNow we will create a simple doubly linked list with three items to understand how this works. In the above code, one, two, and three are the nodes with data items 1, 2, and 3 respectively.

WebSo I have tried to implement a doubly-linked list in C++. My implementation includes some basic methods (although I know there could be many more), an iterator class and an overwritten << operator. I know the code is quite big, but I would really appreciate any comments on functionality, style or anything else you think could be better.
