Why we need Circular Queue in C++? Circular queue concept is especially helpful when the queue is implemented using an array. This is the same as the non-circular EXCEPT that you must update the rear->next value to point to the head when you qRemove (), and set the new rear->next when you qInsert (). A circular queue is a type of queue in which the last position is connected to the first position to make a circle. Here is an article about how to create a circular queue using a circular linked list in C++. In a normal array implementation, dequeue () can be O (n) or we may waste space. when we try to increment the pointer and we reach the end of the queue, we start from the beginning of the queue.
