To understand the circular implementation, think of the array as a circle. Elements are always added to the back of the queue and removed from the front of the queue. In the C++ circular buffer implementation, size and capacity report the number of elements in the queue rather than the size in bytes. If you are already familiar with the basics of such data structures, feel free. Delete an Element from the Queue. Just like Java List, Java Queue is a collection of ordered elements (Or objects) but it performs insert and remove operations differently. So, when we perform more add and delete operations, memory wastage increases. C programming, exercises, solution : Write a program in C to create and display a circular linked list.

In circular queue, the last node is connected back to the first node to make a circle. the element that is inserted first is also deleted first. Many C++ programs use common data structures like stacks, queues and lists. By using the modulo operator, we can view the queue as a circular array, where the "wrapped around" can be simulated as "back % array_size". In this post, we will cover queue implementation in C++ using class and STL. Circular array list fallows the First In First Out principle. Since all device requests are linked in queues, the seek time is increased causing the system to slow down. A circular queue is a queue in which each element has a next pointer that is never null.
