Complete theCircularArrayQueueimplementation by implementing the enqueuing and dequeuing functions inCircularArrayQueue.c.

To get an idea of how these functions should behave, you can refer to the diagrams above. Keep in mind that your enqueuing function must be able to handle the situation where the array containing the items is full and needs to be expanded.

A good rule of thumb is to double the size of the array each time it needs to be expanded. You may want to look intorealloc(3)for expanding the array. (For an example of how to userealloc, you can look atArrayQueue.c).
