What is singly linked list and doubly linked list?

Singly Linked list Each item in the list is called a node and contains two fields  Information field - The information field holds the actual elements in the list  Next address field- The next address field contains the address of the next node in the list. The entire linked list is accessed from an external pointer called the List. Doubly linked list is a collection of node. Each node contains three fields an info field that contains the information stored in the node. The left and right field that contains the address of the node on its left and right. The doubly linked list could be linear, circular and may have a header node.


Convert single linked list to double linked list?

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.

what are the differences between singly link list and doubly link list?

singly linked list stores only the address of next node while doubly linked list stores the address of previous node and next node and hence it is called doubly linked list. In singly linked list only forward traversing is possible while in doubly linked list forward and backward traversal is possible.

What is a singly linked linear list?

A singly linked list is a linked list which only provides links in "one direction". Using a metaphor, a singly linked list is a one way street, while a doubly linked list is a two way street. Once you move forward in a singly linked list, there is no way to go backwards unless you kept your reference/pointer from before. A singly linked list would look like this: start ----> node1---->node2---->node3 ----> NULL You will see that node2 only has a link forward to node3 - it does not have a link backwards to node1, even though node1 has a link forwards to node2. To prevent us from permanently losing access to portions of the linked list, we generally keep a reference/pointer to "start". A doubly linked list would have twice the number of pointers/references as a singly linked list - making it very inefficient to store small datatypes. On the other hand, it would be possible to move both forwards and backwards with a doubly linked list because you have links pointing both forwards and backwards.


What is the different between header file and header pointer?

Header file is a file which is meant to be included into another file during compilation. Examples: string.h, stdio.h, inttypes.h. Header pointer is a pointer to an object called header (for example header of a linked list).
