namespace CollectionsApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            Queue q = new Queue();
 
            q.Enqueue('A');
            q.Enqueue('M');
            q.Enqueue('G');
            q.Enqueue('W');
 
            Console.WriteLine("Current queue: ");
            foreach (char c in q)
                Console.Write(c + " ");
            Console.WriteLine();
            q.Enqueue('V');
            q.Enqueue('H');
            Console.WriteLine("Current queue: ");
            foreach (char c in q)
                Console.Write(c + " ");
            Console.WriteLine();
            Console.WriteLine("Removing some values ");
            char ch = (char)q.Dequeue();
            Console.WriteLine("The removed value: {0}", ch);
            ch = (char)q.Dequeue();
            Console.WriteLine("The removed value: {0}", ch);
            Console.ReadKey();
        }
    }
}
