the card game cribbage
plays the card game cribbage, with
the program playing one hand and the user the other. The program will
initially ask the user if the rules of the game are needed – if so, it
will print out the appropriate section from According
- When the player makes a mistake scoring his hand or crib, provide an
explanation of the correct score. (This is especially useful for beginning
- “Muggins” – if a player mistakenly scores less than
is due, the opponent may claim the overlooked points. (Of course, the
computer never miscalculates!)
- Print a shorter form of all messages – this is only recommended for
users who have played the game without specifying this option.
- Instead of asking the player to cut the deck, the program will randomly
cut the deck.
first asks the player whether he
wishes to play a short game (“once around”, to 61) or a long
game (“twice around”, to 121). A response of
’ will result in a short
game; any other response will play a long game.
At the start of the first game, the program asks the player to cut the deck to
determine who gets the first crib. The user should respond with a number
between 4 and 48, indicating how many cards down the deck is to be cut. The
player who cuts the lower ranked card gets the first crib. If more than one
game is played, the loser of the previous game gets the first crib in the
For each hand, the program first prints the player's hand and whose crib it is,
and then asks the player to discard two cards into the crib. The cards are
prompted for one per line, and are entered as explained below.
After discarding, the program cuts the deck (if it is the player's crib) or asks
the player to cut the deck (if it's its crib); in the latter case, the
appropriate response is a number from 4 to 36 indicating how far down the
remaining 40 cards are to be cut.
After the deck is cut, play starts with the non-dealer (the person who doesn't
have the crib) leading the first card. Play continues until all cards are
exhausted. The program keeps track of the scoring of all points and the total
of the cards on the table.
After play, the hands are scored. The program requests the player to score his
hand (and the crib, if it is his) by printing out the appropriate cards. Play
continues until one player reaches the game limit (61 or 121).
A carriage return when a numeric input is expected is equivalent to typing the
lowest legal value; when cutting the deck this is equivalent to cutting after
the fourth card.
Cards are specified as rank followed by suit, with letters case insensitive. The
ranks may be specified as one of: ‘a’, ‘2’,
‘3’, ‘4’, ‘5’, ‘6’,
‘7’, ‘8’, ‘9’, ‘t’,
‘j’, ‘q’, and ‘k’, or alternatively,
one of: ‘ace’, ‘two’, ‘three’,
‘four’, ‘five’, ‘six’,
‘seven’, ‘eight’, ‘nine’,
‘ten’, ‘jack’, ‘queen’, and
‘king’. Suits may be specified as: ‘s’,
‘h’, ‘d’, and ‘c’, or alternatively
as: ‘spades’, ‘hearts’, ‘diamonds’,
and ‘clubs’. A card may be specified as:
”. If the single letter rank and
suit designations are used, the space separating the suit and rank may be left
out. Also, if only one card of the desired rank is playable, typing the rank
is sufficient. For example, if your hand was “2H, 4D, 5C, 6H, JC, and
KD” and it was desired to discard the king of diamonds, any of the
following could be typed: ‘k’, ‘king’,
‘kd’, ‘k d’, ‘k of d’, ‘king
d’, ‘king of d’, ‘k diamonds’, ‘k of
diamonds’, ‘king diamonds’, ‘king of
