Write a c program to implement circular queue using array

Elements are added at the rear end and the elements are deleted at the front end of the queue. In the Code below there are four parts. First three function to implement three different operations like Insert a node , delete a node and display the list.

The Fourth part is the main function , in that a do while loop is implemented to keep the user engaged and provide him the all the given choices, according to the choice one of the three function get called. The First function checks whether the queue is empty, rear is at last position of queue or Queue is full. If the queue is not full it adds up the item. The Second function checks whether the list is empty, full or it has only one item.

If any node exists, it will delete the node in FIFO order. The Third function will simply print all the elements of the Queue if exist. If not, then it will say Queue is Empty.

Operations on Circular Queue The following are the operations that can be performed on a circular queue: Front: It is used to get the front element from the Queue. Rear: It is used to get the rear element from the Queue. The new element is always inserted from the rear end.

The deletion in a Queue always takes place from the front end. Applications of Circular Queue The circular Queue can be used in the following scenarios: Memory management: The circular queue provides memory management. As we have already seen that in linear queue, the memory is not managed very efficiently. But in case of a circular queue, the memory is managed efficiently by placing the elements in a location which is unused.

CPU Scheduling: The operating system also uses the circular queue to insert the processes and then execute them. Traffic system: In a computer-control traffic system, traffic light is one of the best examples of the circular queue. Each light of traffic light gets ON one by one after every jinterval of time.

Like red light gets ON for one minute then yellow light for one minute and then green light. After green light, the red light gets ON. Enqueue operation The steps of enqueue operation are given below: First, we will check whether the Queue is full or not. Initially the front and rear are set to When we insert the first element in a Queue, front and rear both are set to 0.

When we insert a new element, the rear gets incremented, i. Scenarios for inserting an element There are two scenarios in which queue is not full: If rear!

Circular queue representation The circular queue solves the major limitation of the normal queue. Limitation of the regular Queue Here, indexes 0 and 1 can only be used after resetting the queue deletion of all elements. Here, the circular increment is performed by modulo division with the queue size.
