A card is a game object identified by a rank and a suit. In the War game, cards are represented as short strings such as "2H" for the 2 of hearts or "7S" for the 7 of spades. section 34.2 section 34.3
Use these rules to represent and compare cards:
- Build a deck with four suits—spades, hearts, diamonds, and clubs—and ranks from 2 through 9, producing 32 cards. section 34.2 section 34.4
- Compare cards first by rank; when ranks match, use the order Spades > Hearts > Diamonds > Clubs. section 34.2 section 34.4
- Give each player one card per round, transfer the lower card to the player holding the higher card, and stop when the deck is empty. section 34.5
A card in a player's hand
A Player stores cards as strings in a list. Adding "4D" places the 4 of diamonds in the hand; removing "4D" transfers it to the other player. section 34.3
