What you want is a suite of Card, the cards on the deck are shuffled (so not
ordered), each one must be picked only once.

1)  Have a boolean associated with a card to tell if it has already been
    picked. Here you use the random generator to pick a card (not very
    efficient).

2)  Build an array of cards then swap 2 cards randomly many times, this will
    give you a shuffled cards deck (well an array of card :). Here you use the
    random generator to shuffle the cards.

3)  <put your own design here>

Pascal.
