Circular Queue Data Structure with C++ Program Implementation - Data Structures & Algorithms

nice course and informative, A queue is an abstract data structure that contains a collection of elements. Queue implements the FIFO mechanism i.e the element that is inserted first is also deleted first.

Queue can be one linear data structure. But it may create some problem if we implement queue using array. Sometimes by using some consecutive insert and delete operation, the front and rear position will change. In that moment, it will look like the queue has no space to insert elements into it.

Even if there are some free spaces, that will not be used due to some logical problems. To overcome this problem, we will use the circular queue data structure.
