Reveal a card in a short deck.

★★★

Cutting the deck is a common way to resolve draws in playing card games. One player takes any number of cards (usually approximately half) from a face down full deck and then reveals the card on the bottom of their pile. The second player then takes any card from those remaining in the deck and reveals their card. Higher numbers beat lower numbers regardless of suit. J is 11, Q is 12, K is 13 and A is 14. The alphabetical order of the suit resolves draws. Clubs (C) is lowest followed by diamonds (D), hearts (H) and spades (S) is the highest. In a short deck the lowest number is a 6. Therefore the 6C (the six of clubs) is the lowest card and AS (the ace of spades) is the highest card.

Cut the deck

Make

Write a program that asks the user to pick one of the first thirty-five cards in the deck. All the previous cards are discarded. The computer then picks one of the remaining cards. Whoever has the highest card wins. The result is output to the user.

Success Criteria

Remember to add a comment before a subprogram, selection or iteration statement to explain its purpose.

Complete the main program so that:

  1. The random number generator uses a default seed.
  2. Copies the list of cards into a playing deck identified as “deck”.
  3. Calls the play_game procedure.

Complete the subprogram called play_game that:

  1. Shuffles the playing deck.
  2. Asks the user to enter a number between 0 and 34 (representing the bottom card of their pile.)
  3. Outputs the card drawn. E.g. 8H
  4. Chooses a random card from those remaining for the computer.
  5. Outputs the card drawn. E.g. QD
  6. Calls the output_winner procedure with the two cards as parameters.

Complete the subprogram called output_winner that:

  1. Takes the two cards drawn as parameters.
  2. Calculates who won.
  3. Outputs the winner.

Hint

Modulus 9 will tell you the value of the card because there are 9 cards in each suit. In the case of draws you can look up the index of the card drawn in the cards list to know a card’s relative value.

Typical inputs and outputs from the program would be:

What number card do you want to draw? 0-34 :20
You reveal the 8H
The CPU reveals the AS
CPU wins.

What number card do you want to draw? 0-34 :13
You reveal the 10D
The CPU reveals the 9S
You win!

What number card do you want to draw? 0-34 :18
You reveal the 6H
The CPU reveals the 6S
CPU wins.
