Program to implement Queue using Linked List C++

Today we are going to write a program to implement queue using linked list C++, let’s start with what is queue:

 

What is QUEUE?

implement queue using linked list C++

 

 

A Queue is a particular kind of abstract data type or collection in which the entities in the collection are kept in order and the principal (or only) operations on the collection are the addition of entities to the rear terminal position, known as enqueue, and removal of entities from the front terminal position, known as dequeue. This makes the queue a First-In-First-Out (FIFO) data structure.

  1. good

  2. why do we want to mention the rear->next=NULL

    as we create the node new we are mentioning it np->next=NULL
    if we do rear=np automatically it forms rear->next =NULL

    as a result rear->next=NULL is not required
