What is linked list in C?

A Linked List is a linear data structure. Every linked list has two parts, the data section and the address section that holds the address of the next element in the list, which is called a node. The size of the linked list is not fixed, and data items can be added at any locations in the list.

What is a single linked list?

1. Singly Linked list Singly linked list is also a collection of different nodes. Nodes are further divided into two parts: data and another one is the address to the nest node. We also have the head and tail of the linked list.

What is a circular linked list?

3. Circular linked list: In a circular linked list, the last node points back to the head node, creating a circular structure. It can be either singly or doubly linked. Insertion: Adding a new node to a linked list involves adjusting the pointers of the existing nodes to maintain the proper sequence.

How do you hold a linked list?

A linked list is held using a pointer which points to the first item of the linked list called "head" and a pointer which points to the last item of the linked list called "tail". If that pointer (the "tail") is also nullptr, then the list is considered to be empty. Now we can use the nodes.
