Mar 28, 2025 · In this article, we will discuss how to create a dynamic circular queue using a circular array having the following functionality: Front(): Get the front item from the queue.Back(): Get the last item from the queue.Push(X): Push the X in the queue at the end of the queue.Pop(): Delete an element fro

May 24, 2024 · A circular queue is a type of queue in which the last element is connected to the first element, forming a circular structure. In this article, we'll learn about circular queue, how to implement it in C++, and analyze its complexity.

Jun 2, 2024 · A circular queue is a linear data structure that follows the FIFO (First In, First Out) principle but connects the last position back to the first, forming a circle. In this article, we will learn how to implement circular queue in C programming language.

Circular queue avoids the wastage of space in a regular queue implementation using arrays. In this tutorial, you will understand circular queue data structure and it's implementations in Python, Java, C, and C++.

In this article, I will discuss how to Implement a Circular Queue in C Language with Examples. Please read our previous article about the Drawbacks of Queues using an Array. Now, we will discuss the concept of a circular queue with an example. The problem with a linear queue is that we move the front pointer instead of shifting the elements.

In circular queue it is necessary that: Before insertion, fullness of Queue must be checked (for overflow). Before deletion, emptiness of Queue must be checked (for underflow). Condition to check FULL Circular Queue. Use count variable to hold the current position ( in case of insertion or deletion). Initialize Operation. Is_Full check.

The steps of enqueue operation are given below: First, we will check whether the Queue is full or not. Initially the front and rear are set to -1. When we insert the first element in a Queue, front and rear both are set to 0. When we insert a new element, the rear gets incremented, i.e., rear=rear+1. Scenarios for inserting an element.

To implement queue using circular array : In the enqueue() method we will make rear = (rear+1)%SIZE instead of rear++ . In the dequeue() method we will make front = (front+1)%SIZE , instead of front++ .

There are mainly four operations that can be performed on a circular queue: Enqueue: Insert an element into the circular queue. Dequeue: Delete an element from the circular queue. Front: Get the front element from the circular queue. Rear: Get the last element from the circular queue.

In a circular queue, the first position logically follows the last, forming a loop. This structure eliminates wasted space without the need for shifting. Circular queues can be implemented using a circular array, singly linked list, or doubly linked list, making them ideal for …
