   Jul 7, 2023 · Here we have shown the implementation of a circular queue using an array data structure. Implement Circular Queue using Array: Initialize an array queue of size n, where n is the maximum number of elements that the queue can hold. Initialize two variables front and rear to -1. Enqueue: To enqueue an element x into the queue, do the following:

   Below we have the implementation of a circular queue: Initialize the queue, with size of the queue defined (maxSize), and head and tail pointers. enqueue: Check if the number of elements is equal to maxSize - 1: If Yes, then return Queue is full. If No, then add the new data element to the location of tail pointer and increment the tail pointer.

   Jul 23, 2024 · What is Circular Queue in a Data Structure? A circular queue is an extended version of a linear queue as it follows the First In First Out principle with the exception that it connects the last node of a queue to its first by forming a circular link. Hence, it is also called a Ring Buffer.

   What is a circular queue?

   • A circular queue is the extended version of a regular queuewhere the last element is connected to the first element. Thus forming a circle-like structure. Circular queue representation The circular queue solves the major limitation of the normal queue. In a normal queue, after a bit of insertion and deletion, there will be non-usable empty space.

   How to manage data flow in a queue?

   • The first primary queue operation that allows you to manage data flow in a queue is Enqueue (). For implementing this function, you have to check if the queue is empty. If a circular queue is empty, you must set both the front and rear pointer to 0 manually. This condition can be implemented as follows: Later, you will check if the queue is full.

   What is a fixed size of a circular queue?

   • Fixed size: The size of a circular queue is established at initialization. If the queue is already full, additional components cannot be added without first being dequeued. Circular data structure: A circular queue is a data structure with a circle-like connection between the last and first positions.

   Can a circular queue be implemented with an array or a linked list?

   • The circular queue can be implemented using both an array or a circular linked list but it is most beneficial for array implementation as it resolves the stack overflow condition of the linear implementation even when the whole array is empty. So, here we will only discuss the array implementation of the circular queue

   What are the unique properties of a circular queue?

   • Along with the properties of a regular queue the circular queue has som other unique properties as mentioned below: Front and rear pointers: Two pointers, one at the front and one at the back, are present in a circular queue. The front pointer points to the first member in the queue, while the rear pointer points to the last member in the queue.
