Queue is a linear data structure. The element entered first in queue will leave first. Unlike Stack, Queue can be operated from both end. Elements always enter from read and leaves from front of queue. Following are the fundamental queue operations: Add an element at the rear of the queue.
Removes an element from front of the queue. Returns if queue is empty. Returns front element of queue without removing it from queue. We have to implement a Queue data structure using singly linked list. Linked list implementation of queue data structure must support basic queue operations like enqueue, dequeue, getQueueSize and isEmpty.
Given a singly linked list whose node structure is as follows: This will ensure that we will add node at rear of linked list and remove node from front of linked list. We will start with an empty linked list, where both front and back pointer is set to NULL.
We will dynamically allocate memory for a struct node variable let's say temp. Finally set back pointer to temp. Remove head node pointed by front pointer of the linked list. Store the front pointer in a temp variable.
Deallocate memory of temp node using free. Returns the value of head node of linked list without removing it.Representation of Queue as an Array.
Queue is a linear data structure can be represented by using arrays. Here is a program showing the implementation of a queue using an array.
Program of Circular Queue using c++ Write a program to split one linked list into two list. Write a program to search a number using Linear Se A Program to Split an array into 2 arrays; A Program to merge two arrays; A Program to insert and deletion of an element at/.

How can you represent Linear Linked List in mem STACKS USING ARRAYS implementation in C++. An array of linked list is an interesting structure as it combines a static structure (an array) and a dynamic structure (linked lists) to form a useful data structure.
This type of a. Stacks, Queues, and Linked Lists 5 An Array-Based Stack • Each process running in a Java program has its own Java Method Stack. • Each time a method is called, it is pushed onto the • To implement a deque, we use adoubly linked list.
