Description

Build a casino where the user can play the following games.

1)Lucky Seven

2)High Card

3)Match Card (Bonus)

The user starts with $100. The user is then prompted to pick a game. All inputs must be error checked. The user is then asked how much they want to bet on the game. (Cannot be 0 or more than the user currently has.) Depending on the users outcome, the user either wins or loses the amount they bet. All the games require a deck of cards (simulated with an array). The cards will need to be shuffled before each game. The user is kicked out of the casino if they have no money left.

Game Descriptions

Lucky Seven

The user draws a card. If the card value is equal to 7, the user wins 7X the amount bet. If the card value is not 7, the user loses the amount bet.

High Card

The user draws a card from the deck, and the computer picks a random (different) card. If the computers card is higher, then the player loses. If the players card is higher, then the player wins. For this version, all cards are different numbers.

Match Card (Bonus Only)

The user does not bet for this game. Works similar to high card, except there will be 4 decks of cards in play. (Use a 2D array) The user will choose a deck and a card. The computer will pick a random card from a random deck. If the value of the users card matches the computers card

, then the user doubles their total money. If the user loses, then the user loses everything.

Random Number Generator

Use the rand() function from to generate random numbers. The output will need to be between 0-12 for card operations. Use rand() and the % operator. SIZE is a global constant. Treat it like a variable that you cant change. Use it for all card operations where you need the value for size of the deck.

To use the functions srand and rand:

#include

#include

#define SIZE 13 //You are dealing with only 13 cards not 52 just an FYI

Goes at the top of your code, and:

srand(time(NULL));

As the first line of code inside of main()

Win/loss calculation table

Example

For Lucky Seven, if the user has an initial amount of $100, bets $25 and wins, then total = 100 + 7 * 25->$275

If they lose, then the total = 100 - 25 -> $75

Function Prototypes & Descriptions

void display_menu();

/*

Displays the menu for choosing a game. Should only have printf statements.

Arguments None

Return Nothing

*/

int error_check(int);

/*

Argument int: option chosen in main

Check if the options chosen is valid or not

Returns 1 if input is valid, 0 otherwise.

*/

void shuffle(int[]);

/* Argument int Array signifying deck of cards, which was created in main

Return Nothing

Takes in the deck of cards array, loads with values from 1-13 and shuffles the order. Do not create a new array. Hint: Pass by reference!

Remember: Index of an array starts from location 0, your deck must have card values from 1-13. To shuffle the order use rand() function to get a random index and then swap the values. Example: After loading the deck with values from 1-13 in the locations 0-12, your deck is loaded. Now to shuffle, as of now at location 0, value is 1 and at location 1 value is 2 and so on. Imagine rand() returns a random index 3(which has the card value 4 in it now), you have to swap this with whatever is in location 0. This was just a one-time swap; you have to do it for all the 13 locations. How do you do it??

Hint: Bubble sort logic (but you are not sorting anything here).

*/

int draw_card(int[]);

/*

Picks the first card that hasnt been drawn already, marks it as taken and

returns the value of the card.

Change value to -1 at the location to indicate taken

Arguments int[] deck of cards, which was created in main()

return int: value of card drawn.

*/

int lucky_seven(int);

/*

Implements lucky seven game logic. Takes in one card value and checks if it is equal to 7.

return 1 if value matches indicating the user won, return 0 if user loses.

*/

int high_card(int, int);

/*

High Card game logic. Takes in card values and checks which one is higher.

return 1 if user card is greater than dealer card indicating user wins, return 0 if user loses.

*/

double calculate_winnings(int, int, double);

/*

Calculates winnings based on game played and if the user won.

Arguments- int: game played, int: win or loss, double: amount bet

return double: amount won or lost.

Refer the table above.

*/

int match_card(int, int); // Bonus

/*

Game is only played when the user decides to quit. (Give them a last minute chance to double their money)

Takes in card values and checks if they are the same.

return 1 if user wins, return 0 if user loses

*/

int main(void) {}

/*

Acts as user interaction, creates arrays, calls other functions, keeps track of users total money.

First display the menu of games to play.

Declare all the variable you need to use and also the array representing the deck

Every time a game is played, display the amount the user has left and ask the user to enter the amount he wants to bet. Assume the user wont mess up (brownie points if you check this too).

Next, display the result of the game (display if the user won or lost, display the card(s) drawn, and the amount of money gained/lost).

Continue to play the game as long as user does not choose to exit and still has money.

Display final amount of money when the user quits or gets thrown out.

For the bonus, create a 2D Array representing 4 decks of 13 cards each. Shuffle each deck and choose two random cards from two different decks. Display cards drawn and if the user won or lost.
