What is a linked list in C++?

Linked List in C++ is data structures and alternative to arrays, where every node of the linked list is made up of two parts data and pointer. Data: It stores the data of the node. Pointer: It stores the address of the next node. What is a Linked List ? A linked list is a chain of nodes that are connected to one another using pointers.

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 doubly linked list in C++?

The C++ doubly linked list has nodes that can point towards both the next and the previous node. A node has two parts: the data part and the next part. The data part contains the stored data, and the next part provides the address of the next node. The first node of a linked list is called the head, and the last node is called the tail.

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.
