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++.

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.

Mar 28, 2025 · A Circular Queue is a way of implementing a normal queue where the last element of the queue is connected to the first element of the queue forming a circle. The operations are performed based on the FIFO (First In First Out) principle.

Learn about the Circular Queue Data Structure, its properties, operations, and applications in computer science.

Jul 23, 2024 · In this tutorial, you explored the circular queues in a data structure. A circular queue resolves memory wastage drawback, which is faced in the implementation of a linear queue. You also went through the steps to implement primary circular queue operations.

This section provides you a brief description about Circular Queue in Data Structure Tutorial with Algorithms, Syntaxes, Examples, and solved programs, Aptitude Solutions and Interview Questions and Answers.

1 day ago · The efficient approach to avoid the wastage of the memory is to use the circular queue data structure. What is a Circular Queue? A circular queue is similar to a linear queue as it is also based on the FIFO (First In First Out) principle except that the last position is connected to the first position in a circular queue that forms a circle.

In a circular queue, enQueue () is a function which is used to insert an element into the circular queue. In a circular queue, the new element is always inserted at rear position. The enQueue () function takes one integer value as parameter and inserts that value into the circular queue.

Circular queue is just like a normal queue with no end, after the queue reaches its last index it starts again from the first. This tutorial covers circular queue implementation, applications of circular queue and is best suited for beginners.

A circular queue is a linear data structure where the last position connects back to the first, forming a circle. It efficiently uses memory by reusing freed spaces from dequeued elements.
