I'm sure that this has been discussed at length and my input may be very late and outdated, but.... I think I may have found a more effecient answer for question 4 than the book currently suggests (though I was thinking about case statements initially too).

Here is my solution:

    class PrintCardDeck
    {
        static void Print()
        {
            string[] Suits = { "Spades", "Hearts", "Diamonds", "Clubs" };
            string[] Cards = { "2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King", "Ace" };

            foreach (string Suit in Suits)
            {
                foreach (string Card in Cards)
                {
                    Console.WriteLine("Card: " + Suit + " / " + Card);
                }
            }
            Console.Read();
        }
    }
