Questions and Answers

Explain the concept of a doubly linked list and its components.

A doubly linked list is a type of linked list where each node contains three components: the data, a pointer to the next node, and a pointer to the previous node.

What is the purpose of the 'prev' and 'next' components in a doubly linked list?

The 'prev' component stores the address of the previous node, while the 'next' component stores the address of the next node, allowing bidirectional traversal of the list.

Describe the process of adding a new node to a doubly linked list.

To add a new node to a doubly linked list, memory is allocated for the new node, the data is assigned, and then the pointers of the new node and the neighboring nodes are adjusted to maintain the linkage.

What is the role of the 'head node' in a doubly linked list?

<p>The head node serves as the starting point for traversing the doubly linked list and is used to store the address of the first node in the list.</p> Signup and view all the answers

Explain the traversal of a doubly linked list using the 'PrintList' function.

<p>The 'PrintList' function takes the head node as input and traverses the doubly linked list, printing the data of each node as it moves through the list.</p> Signup and view all the answers
