2 A Game of UNO

You are to develop an interactive game of UNO between a number of players. The gameplay for UNO is described

at https://www.unorules.com/. Your program should operate as follows.

2.1 Setup

1. UNO cards are represented as variables of the following type:

typedef struct card_s {

char suit[7];

int value;

char action[15];

struct card_s *pt;

} card;

You are allowed to add attributes to this definition, but not to remove any. You can represent colors

by using card suits. Red: hearts; Yellow: diamonds; Green: clubs; Blue: spades. The action field is

used to denote the function of action cards.

2. The game is played using the following deck of cards1.

Figure 1: The deck of UNO cards.

The following action cards are included:

_ Reverse { If going clockwise, switch to counterclockwise or vice versa.

_ Skip { When a player places this card, the next player has to skip their turn. If turned up at the

beginning, the _rst player loses his/her turn.

_ Draw Two { When a person places this card, the next player will have to pick up two cards and

forfeit his/her turn.

_ Wild { This card represents all four colors, and can be placed on any card. The player has to

state which color it will represent for the next player. It can be played regardless of whether

another card is available.

_ Wild Draw Four { This acts just like the wild card except that the next player also has to draw

four cards as well as forfeit his/her turn. With this card, you must have no other alternative cards

to play that matches the color of the card previously played. If you play this card illegally, you

may be challenged by the other player to show your hand to him/her. If guilty, you need to draw

4 cards. If not, the challenger needs to draw 6 cards instead.

3. At the beginning, the user can choose to shu_e the deck or load a prede_ned sequence of cards from

a _le (for testing).

4. The deck is implemented by a dynamic list of cards. The cards drawn from the deck are deleted from

the list.

5. Each player's hand is implemented by a dynamic list of cards. The list is initially populated with the

cards dealt to each player. The card drawn (played) by each player is added to (deleted from) the

respective list.

6. The discard pile is implemented by a dynamic list. The discard pile is shu_ed if the draw pile is

exhausted and the game has not ended. Only the top _ve cards of the discard pile are shown on screen.

2.2 GamePlay

The gameplay and scoring process are described at https://www.unorules.com/

1. Automate one of the players. Modify your code to implement one of the players automatically.

2. Players 2{10. Allow the game to be played by any number of players from 2{10.

3. Game Variations. Implement the following game variations.

(a) Progressive Uno. If a draw card is played, and the following player has the same card, they

can play that card and \stack" the penalty, which adds to the current penalty and passes it to

the following player.

(b) Seven-O.: When a certain card is played, the player is able to trade hands with another player

or with all players. For example, the person who played the 7 card is able to switch all of their

cards with another player; the player who played the 0 card is able to make every player exchange

all their cards to the next player.

4. Graphics. Add graphics to your game. You can print cards using ascii art.

2.4 Sample Execution

Let's Play a Game of UNO

Press 1 to shuffle the UNO deck or 2 to load a deck from a file: 1

The deck is shuffled. Press any key to deal cards

Discard pile: 5|

Player's one hand: 6|, 3|, wild, draw two, 9V, 2; 7

3

Press 1-7 to play any card from your hand, or press zero to draw a card from the deck:5

The 9V cannot be placed on top of 5|

Press 1-7 to play any card from your hand, or press zero to draw a card from the deck:1

Discard pile: 6|, 5|

Player's two hand: 3|, 5V, 2W, reverse, 6V, 2|; 7

...

Player's one hand: 9V

Player one has UNO

Press 1 to play the card from your hand, or press zero to draw a card from the deck:1

Discard pile: 9V, 4V, 6V, wild, 2W.

Player 1 wins

Would you like to play again (y/n)? n

Bye bye

-------------------------------------------------------------------------------------------------------------------------

Use Stdio.h

Make sure the game cab be played between 2-10 players

Also, create an automatic player and ask the user if he want to play with him or not
