what are the main applications of double linked list?
1. Applications that have an MRU list (a linked list of file names)
2. The cache in your browser that allows you to hit the BACK button (a linked list of URLs)
3. Undo functionality in Photoshop or Word (a linked list of state)
4. A stack, hash table, and binary tree can be implemented using a doubly linked list.
5. A great way to represent a deck of cards in a game.
You copy a singly linked list into a doubly linked list by iterating over the singly linked list and, for each element, calling the doubly linked list insert function.
You may store received SMS's in a linked list:typedef struct RecvSMS {struct RecvSMS *next;PhoneNum from;time_t recvdate;char *text;} RecvSMS;
A list is an abstract data structure, usually defined as an ordered collection of data. A linked list refers to a specific implementation of a list in which each element in the list is connected (linked) to the next element.
If people started writing these codes here, then what software engineers will do?
Answersingly linked list has the node inserted only at one end. and the pointer corresponds to the next pointer.but in a doubly linked list, the node pointer points to the both previous and the next node.singly linked list has two nodesdoubly linked list has three nodesA doubly linked list makes sense when you need to traverse the list in both directions. You aren't able to do that with a singly linked list.
Outside of academia I do not think linked list are important, a btree is important. As for a real-world application, I do not recall one. I did use a linked list back in the days of the Apple 2/Commodore 64 but That was before hard drives (were affordable) and before I got my hands on btree source code.

Good question, it defies an answer because I do not have the text book that your teacher is posing questions from. Besides when you have a btree linked lists look kind of stupid.
It is easier to insert into a singly linked list.
A list is an abstract data structure, usually defined as an ordered collection of data. A linked list refers to a specific implementation of a list in which each element in the list is connected (linked) to the next element.
Linked list of strings, for example.

A doubly linked list is a linked list in which each node knows where both of its neighbors are.A circular linked list is a linked list in which the "tail" of the list is linked to the "root". (Note that both the tail and root of the list are undefined/arbitrary in a circular linked list)Doubly linked lists are actually not necessarily related to circular linked list (aside from both being based on a linked list structure). In fact, you can have a circular doubly linked list, where each node knows where both of its neighbors are andwhere the list wraps around to connect to itself.

linked list are used for creation of stack,queues to use memory in optimum manner linked list are used as they are dynamic in nature
