Doubly Linked List In Data Structure Program In C

Step 1 check whether list is empty head null step 2 if it is empty then display list is empty and terminate the function.

Doubly linked list in data structure program in c. Doubly linked list is a type of linked list in which each node apart from storing its data has two links. Go back in the reverse direction. The only difference is that there is another address variable which help is traversing the list better in a doubly linked list. The previous link of the first node and the next link of the last node points to null.

Displaying a double linked list. Doubly linked list is a type of linked list data structure which behaves like a two way list chain. Doubly linked list is a more sophisticated form of linked list data structure. The first link points to the previous node in the list and the second link points to the next node in the list.

Step 3 if it is not empty then define a node pointer temp and initialize with head. Doubly linked list is a variation of linked list in which navigation is possible in both ways either forward and backward easily as compared to single linked list. Linked list is the second most used data structure after array. I hope you have understood how to perform basic operations on singly and doubly linked list in c.

Each node of the list contain two references or links one to the previous node and other to the next node. Today we will discuss c program for insertion at beginning in doubly linked list in which we have to insert node at the end of the doubly linked list the doubly linked list have three field such as the node have the data pointer which points next node in series and pointer which points previous node of the list it is quite complicated than singly. Each link contains a connection to another link. We can use the following steps to display the elements of a double linked list.

Linked list is a sequence of links which contains items. A linked list is a sequence of data structures which are connected together via links. Insertion at the beginning of the linked list.
