What is linked list in C++?

Linked List is the part of the data structure and most important as well. In C++ linked list is implemented by using structure and pointers. The basic working of the link is the same in all programming languages like it is the collection of many nodes together, and nodes contain data and address of the next node.

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.
