printf("\n%d is inserted in queue\n",add_item); printf("-----\n"); rear = rear + 1; queue_array[rear] = add_item; }} void delete() { if (front == - 1 || front > rear) { printf("Queue Underflow \n"); return ; } else { printf("\nElement deleted from queue is : %d\n", queue_array[front]); printf("--- …

Mar 16, 2021 · Step 1 : If front = 1 and rear=N or front =rear+1. Then print “OVERFLOW’ and return. Step 2 : If front = Null then. Set front = 1 and rear =1. Else if rear = N then set rear = 1. Set rear = rear + 1. End if. Step 3: SetQueue [rear]=item. Step 4 : stop. (b) Deletion operation.

May 27, 2024 · A queue is a linear data structure that follows the First-In-First-Out (FIFO) principle which means the elements added first in a queue will be removed first from the queue. In this article, we will learn how to implement a Queue using Array in C.

Mar 12, 2025 · Deque or Double Ended Queue is a generalized version of the Queue data structure that allows insert and delete at both ends. Operations on Deque:Â Mainly the following four basic operations are performed on queue:Â insertFront(): Adds an item at the front of Deque.insertRear(): Adds an item at the r

Insertion is performed from REAR end. Deletion is performed from FRONT end. Insertion operation is also known as ENQUEUE in queue. Queue can be implementing by two ways: Array or contiguous implementation. Linked List implementation. In Array implementation FRONT pointer initialized with 0 and REAR initialized with -1.

Mar 28, 2025 · Simple Queue: Simple Queue simply follows FIFO Structure. We can only insert the element at the back and remove the element from the front of the queue. A simple queue is efficiently implemented either using a linked list or a circular array.

As a small example in this tutorial, we implement queues using a one-dimensional array. Queue operations also include initialization of a queue, usage and permanently deleting the data from the memory. The most fundamental operations in the queue ADT include: enqueue (), dequeue (), peek (), isFull (), isEmpty ().

Apr 13, 2012 · we can not insert element directly at middle index (position) in Queue and vice verse for deletion. insertion operation possible at REAR end only and deletion operation at FRONT end, to insert we increment REAR and to delete we increment FRONT. Input : An element say ITEM that has to be inserted. Output : ITEM is at the REAR of the Queue.

The implementation of queue data structure using a one-dimensional array is very simple and easy. This requires a one-dimensional array of well-defined size. Then insert or delete operation can be performed on that array by using the First In First Out (FIFO) property.

Apr 10, 2017 · Here’s simple Program to implement queue operations using array in C Programming Language. What is Queue ? 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.
