Question
Chapter 18, Problem 15RQE
Program Plan Intro
Queue:
- A queue contains sequence of items.
- The item which is inserted first is retrieved first.
- Queue performs “First In First Out”.
Operations performed on Queue:
A queue can perform two operations. They are:
- Enqueue
- Dequeue
Enqueue:
Insertion of an element into the queue is called as Enqueue. The elements can be inserted at any end of the queue. The sides in which the items are inserted are called as “Rear”.
Dequeue:
Retrieving an element from the queue is known as Dequeue. The sides in which the items are retrieved are called as “Front”.

Suppose the following operations are performed on an empty queue:enqueue(5);enqueue(?);dequeue();enqueue(9);enqueue ( 12);dequeue();enqueue(10);Insert numbers in the following diagram to show what will be stored in the staticqueue after the operations have executed .front rear
Note : addqueue works like Enqueue and deleteQueue works like Dequeue
Consider the following statements: (8, 9)
queueType queue;
int num;
Show what is output by the following segment of code
num = 7;
queue.addQueue (6);
queue.addQueue (num);
num = queue.front ();
queue.deleteQueue();
queue.addQueue (num + 5);
queue.addQueue (14);
queue.addQueue (num
queue.addQueue (25);
queue.deleteQueue ();
2);
cout <« "Queue elements: ";
while (!queue.isEmptyQueue ())
{
cout <« queue.front () << " ";
queue.deleteQueue();
}
cout <« endl;

Deque is an acronym meaning "double-ended queue." With a deque, you may insert, remove, or view from either end of the queue, which distinguishes it from the other two. Use arrays to implement a dequearrow_forwardb.
