// CardCount is a helper library for CardStacks.
|
|
//
|
|
// When you initialize a CardCount object with a
|
|
// cardstack, it keeps track of the number of cards
|
|
// the stack contains.
|
|
//
|
|
// e.g. CardCount count(cardstack);
|
|
//
|
|
// Then you can do:
|
|
//
|
|
// int num_fives = count[5]
|
|
//
|
|
// count.Add(cardstack2); - combine with another stack
|
|
//
|
|
// int num_aces = count[1] - aces low
|
|
// int num_aces = count[14] - aces high
|
|
//
|
|
// count.Clear();
|
|
//
