May 14, 2024 · In this article, we will learn how to write a program to implement queues using an array in C++. The queue is a linear data structure that has the following properties:- It has mainly 2 pointers to perform operations: Front & Rear. The Rear is …

Mar 12, 2025 · To implement a queue of size n using an array, the operations are as follows: Enqueue: Adds new elements to the end of the queue. Checks if the queue has space before insertion, then increments the size. Dequeue: Removes the front element by shifting all remaining elements one position to the left. Decrements the queue size after removal.

Learn how to implement a queue using an array in C++ with this detailed guide and code examples.

Jan 4, 2012 · So far you have only demonstrated that you can use a library class called "queue". You can implement queue with a circular buffer/circular array. Check this link to get some idea vias.org/cppcourse/chap20_05.html.

Mar 5, 2025 · Introduction : One efficient way to implement k queues in a single array is to use a technique called "circular array implementation of k queues." This approach uses a single array to store elements for all k queues, and it divides the array into k segments, one for each queue.

Jul 23, 2024 · Code in C++: Menu-Driven Program for Queue Implementation Using Array. Now that you are clear with the building blocks of queue operation, it’s time to dive in further and formulate a menu-driven C++ program to visualize a queue using an array data structure.

Jan 29, 2023 · A linear queue can be implemented using an Array. Firstly define an array of the desired type, a Front, and a Rear variable. Then, implement the enqueue(), dequeue(), and peek() functions to insert, delete, and fetch the elements respectively.

One of the common ways to implement a queue is using arrays. The elements are inserted at the front of the queue and removed from the rear of the queue. Before you learn about how to implement a queue, be familiar with the concept of arrays and queue.

Apr 14, 2025 · Write a C++ program to implement a circular queue using an array that supports enqueue, dequeue, and full/empty checks. Write a C++ program to simulate a priority queue using an array where insertion is based on a priority value.

Oct 24, 2019 · In array implementation of queue, we create an array queue of size n with two variables top and end. Now, initially, the array is empty i.e. both top and end are at 0 indexes of the array. And as elements are added to the queue (insertion) the end variable's value is increased. The value of the end can increase up to n i.e. max length of an array.
