//declare and initialize a Queue
Queue que = new Queue();
//insertting elements
que.Enqueue(100);
que.Enqueue(200);
que.Enqueue(300);
que.Enqueue(400);
que.Enqueue(500);
//printing length
Console.WriteLine("Total elements: " + que.Count);
//printing queue elements
Console.WriteLine("Queue elements are...");
printQueue(que);
//removing all elements
