Why we need Circular Queue in C++?
Circular queue concept is especially helpful when the queue is implemented using an array. In linear implementation, when the rear pointer reaches the end of the queue, we cannot insert new elements even if there are empty locations in the queue.
Circular queues address this limitation by connecting the front and rear ends, allowing the rear to go back to the start in when the rear reaches the end of the queue.
C++ Program to Implement Circular Queue
In C++, Queues are a fundamental data structure in computer science which works on the principle of FIFO (First In, First Out). They can be implemented using both array and linked list. 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.
