Blog Circular queues A circular queue is a type of queue in which the front and rear pointers can move over the two ends of the queue , making for a more memory efficient data structure. Sarah Asha When the operation Queue.Enqueue(“Hans”) is performed on the circular queue A Circular Queue can be seen as an improvement over the Linear Queue because: There is no need to reset Head and Tail pointers since they reset themselves. This means that once the Head or Tail reaches the end of the Queue, it resets itself to 0. The Tail and Head can point to the same location - this means the Queue is emptyImplementation of the Circular Queue All types of queues can be implemented by using either of the following ways - Arrays Linked List Let us discuss both the approaches here for circular queues - Implementation using arrayDec 12, 2012 · Circular Queue Implementation as C++ Template.

In the linear queue, we can't insert an element in the queue if the rear is pointing to the last index of the queue and the queue is not completely filled. This causes wastage of memory. To overcome this wastage we use the circular queue.Mar 28, 2022 · In order to solve this problem, a new queue appears - Circular queue .

The following paragraphs describe issues that had to be considered during the implementation of the circular_buffer: Thread-Safety. The thread-safety of the circular_buffer is the same as the thread-safety of containers in most STL implementations. This means the circular_buffer is not fully thread-safe. circular-queue.c. C program to insert (Enqueue) and delete (Dequeue) elements in a Circular Queue which is implemented using an array is as follows: To implement a circular queue data structure using an array, we first perform the following steps before we implement actual operations.
