You create a Linked List with classes or structs. The programmer gives it a data value, in this case an int called data, a pointer to the next node in the Linked List, as well as a constructor to create the list. This is a representation of a Linked List in C++.

Linked lists consist of a series of nodes scattered throughout memory. Each node has the data it stores and a reference to the next node in the linked list chain. The beginning node is called the head and the end node points to null. It’s also a building block for other DS such as stacks and queues.
