Learn How To Implement of Queue using Array in C Programming. A Queue is a linear structure which follows a particular order in which the operations are performed. Queue implements the FIFO mechanism i.e. In this lecture I have described array based implementation of queue data structure. TICKET WINDOW - Program Using Queue. Prerequisite – Queues Circular Queue is a linear data structure in which the operations are performed based on FIFO (First In First Out) principle and the last position is connected back to the first position to make a circle. Queue is also an abstract data type or a linear data structure, in which the first element is inserted from one end called REAR , and the deletion of existing element takes place from the other end called as FRONT. C++ Programming Server Side Programming A queue is an abstract data structure that contains a collection of elements. QUEUE has two pointer FRONT and REAR, Item can be pushed by REAR End and can be removed by FRONT End. In this tutorial, you will learn what a double ended queue (deque) is. Only the head pointer is incremented by one position when dequeue is executed. To learn the theory aspect of st In previous post, I explained about queue implementation using array. Insertion in a queue is done using enqueue function and removal from a queue is done using dequeue function. The concepts and the codes of a linked list are explained in the article “Linked list in C”. Array-based implementation – It’s simple and efficient but the maximum size of, Singly Linked List-based implementation – It’s complicated but there is no limit. 1. createQueue function– This function takes the maximum number of elements. We will learn how to implement queue data structure using array in C language. Thus it is called a circular queue. C Program to Implement Queues using Arrays #include #define SIZE 5 //Basic value initialisation int queue[SIZE], front = -1, rear = -1; //Function created to handle enqueue void enqueue(int item){if(rear == SIZE-1){printf("Can't enqueue as the queue is full\n");} else{//The first element condition if(front == -1){front = 0;} rear = rear + 1; The program output is also shown in below. In the concept of a queue, the first element to be inserted in the queue will be the first element to be deleted or removed from the list. MCQ Quizzes- Test your C Programming skills!
