Question

Modify the craps application of fig 7.8 to allow wagering. Initialize variable balance to 1000 dollars. Prompt the player to enter a wager. Check that wager is less than or equal to balance, and if it's not, have the user reenter wager until a valid wager is enters. After a correct wager is entered, run one game of craps, if the player wins, increase balance by wager and display the new balance, if the player loses, decrease balance by wager, display the new balance, check whether balance has become zero and, if so display the mess "Sorry. You busted!" // Fig. 7.8: Craps.cs // Craps class simulates the dice game craps. using System; public class Craps { // create random number generator for use in method RollDice private static Random randomNumbers = new Random(); // enumeration with constants that represent the game status private enum Status { CONTINUE, WON, LOST } // enumeration with constants that represent common rolls of the dice private enum DiceNames { SNAKE_EYES = 2, TREY = 3, SEVEN = 7, YO_LEVEN = 11, BOX_CARS = 12 } // plays one game of craps public static void Main( string[] args ) { // gameStatus can contain CONTINUE, WON or LOST Status gameStatus = Status.CONTINUE; int myPoint = 0; // point if no win or loss on first roll int sumOfDice = RollDice(); // first roll of the dice // determine game status and point based on first roll switch ( ( DiceNames ) sumOfDice ) { case DiceNames.SEVEN: // win with 7 on first roll case DiceNames.YO_LEVEN: // win with 11 on first roll gameStatus = Status.WON; break; case DiceNames.SNAKE_EYES: // lose with 2 on first roll case DiceNames.TREY: // lose with 3 on first roll case DiceNames.BOX_CARS: // lose with 12 on first roll gameStatus = Status.LOST; break; default: // did not win or lose, so remember point gameStatus = Status.CONTINUE; // game is not over myPoint = sumOfDice; // remember the point Console.WriteLine( "Point is {0}", myPoint ); break; } // end switch // while game is not complete while ( gameStatus == Status.CONTINUE ) // game not WON or LOST { sumOfDice = RollDice(); // roll dice again // determine game status if ( sumOfDice == myPoint ) // win by making point gameStatus = Status.WON; else // lose by rolling 7 before point if ( sumOfDice == ( int ) DiceNames.SEVEN ) gameStatus = Status.LOST; } // end while // display won or lost message if ( gameStatus == Status.WON ) Console.WriteLine( "Player wins" ); else Console.WriteLine( "Player loses" ); } // end Main // roll dice, calculate sum and display results public static int RollDice() { // pick random die values int die1 = randomNumbers.Next( 1, 7 ); // first die roll int die2 = randomNumbers.Next( 1, 7 ); // second die roll int sum = die1 + die2; // sum of die values // display results of this roll Console.WriteLine( "Player rolled {0} + {1} = {2}", die1, die2, sum ); return sum; // return sum of dice } // end method RollDice } // end class Craps
