A game of Craps (Ruby and Java)

This week i have been reading lots about c language and "programming logics and design". We are supposed to learn C programming and develop a game in the end of this module assignment.

In one example we are writing a game of craps in c... C is just too much typing, and hard to keep control over all syntax' for a newbie, but still learning! :D
Although we are programming in C, i first wrote the program in ruby wich gave me a much clearer understanding of what to do in C.(except from classes and rest of easy ruby syntaxes)

Even if you don't know much about programming, i guess you should be able to understand what the program does.

class Craps

    def initialize

        puts "A game of craps"

        first_roll

    end

    def first_roll

        roll = roll_dice

        case roll

        when 7,11

            game_won

        when 2,3,12

            game_lost

        else

            puts "Your point is: " + roll.to_s

            @my_points = roll

            keep_rolling

        end

    end

    def roll_dice

        #dice = (1+rand(6)) + (1+rand(6))

        die1 = 1+rand(6)

        die2 = 1+rand(6)

        dice = die1 + die2

        puts "You rolled: #{die1} + #{die2} = #{dice}"

        return dice

    end

    def game_won

        puts "You win"

        exit

    end

    def game_lost

        puts "You lose"

        exit

    end

    def keep_rolling

        roll = roll_dice

        case roll

        when @my_points

            game_won

        when 7

            game_lost

        else

            while roll

                case roll_dice

                when @my_points

                    game_won

                when 7

                    game_lost

                end

            end

        end

    end

end

play = Craps.new

# Output:

# A game of craps

# You rolled: 5

# Your point is: 5

# You rolled: 12

# You rolled: 8

# You rolled: 5

# You win

I will not paste the C program here, since its pretty similar to the example in "C how to program" by Deitel and Deitel. Boooring! >)

A game of craps (Java)

The java version is just the same. The java syntax' are pretty easy to learn after studying C the last couple of weeks. Java is the language to learn if i ever want to make an android app... but... do i? o_O

I seem to love this game... maybe not, but its an easy way to learn, among other well written programs.

import java.util.Random;

class Craps {

private Random randomizeDice = new Random();

int my_point;

int roll = 0;

public void game_won() {

System.out.println("You win!");

System.exit(0);

}

public void game_lost() {

System.out.println("You lose!");

System.exit(0);

}

public void first_roll() {

roll = roll_dice();

switch (roll) {

case 7:

case 11:

game_won();

case 2:

case 3:

case 12:

game_lost();

default:

my_point = roll;

System.out.println("Your point is: " + my_point);

}

}
