#HEADS or TAILS

Hello again! Today’s game is called HEADS or TAILS, but with a twist… You have money and bets!

In other words, you input how much money you have and how much you’re willing bet.
You either bet HEADS or TAILS (duh…), if you win, you’ll multiply the money you bet by two and add to your existing money; if you fail, you lose the money you bet.

Simple, right?

I chose to polish up my program (even though it has some bugs) to add more syntactical clarity , but you can simply code a quick, functional program.

As always, feel free to post your code in other languages!

Happy Coding!

from random import randint

def game():
    mon = int(raw_input('\n[*] How much money do you have? > '))
    while mon > 0:
        r = randint(0,1) #generates either 0 or 1.  1 = 'heads'; 0 = 'tails'
        bet = int(raw_input('[*] Place your bet > '))
        if bet > mon:
            print "\n[!] You don't have that much money!"

        elif mon == 0:
                print '\n[!] You are out of money!\n'

            else:
                hd = raw_input('\n[*] All right, the million dollar question, HEADS or TAILS? > ')
                if (hd == 'heads' and r == 1) or (hd == 'tails' and r == 0):
                    print '\n[!] You won!\n'
                    mon += bet * 2
                    print '> You now have %s!\n' % (mon)

                elif (hd == 'heads' and r == 0) or (hd == 'tails' and r == 1):
                    print '\n[!] You lost...\n'
                    mon -= bet
                    print '> You now have %s!\n' % (mon)

                else:
                print '\n[!] Please choose HEADS or TAILS\n'

def main():
    print '#----------------#'
    print '| HEADS OR TAILS |'
    print '|    by n3xUs_   |'
    print '#----------------#'

    print '\n[*] This game is simple. You either choose HEADS or TAILS.\n'
        print '[*] If you win, you multiply the money you bet, if you lose, you lose the money.\n'
        print '[*] Simply input how much money you have and how much you want to bet.'

Here’s some C++ this time:

#include <iostream>
#include <string>
#include <algorithm>
 
void game() {
    std::cout << "[*] How much money do you have? ";
    int user_money; std::cin >> user_money;
 
    int user_bet, user_guess, toss;
    while (user_money > 0) {
        std::cout << "[*] Place a bet. ";
        std::cin >> user_bet;
        if (user_bet > user_money) {
            std::cout << "Your bet was too large! Try again..." << std::endl;
            continue;
        }
        while (true) {
            std::cout << "Guess: 0 for heads, 1 for tails. ";
            std::cin >> user_guess;
 
            toss = rand() % 2;
 
            if (user_guess >= 0 && user_guess <= 1) {
                std::cout << "You guessed " << (user_guess == 0 ? "heads" : "tails")
                    << " and were ";
                if (toss == user_guess) {
                    std::cout << "correct!";
                    user_money += user_bet;
                } else {
                    std::cout << "incorrect!";
                    user_money -= user_bet;
                }
                std::cout << std::endl;
                break;
            } else {
                std::cout << "Invalid guess. Try again...";
            }
        }
 
        std::cout << "You now have $" << user_money << ".\n";
    }
 
    std::cout << "You're out of money." << std::endll;
}
 
int main() {
    std::cout << "[*] Heads or Tails [*]" << std::endl
        << "You will bet on the outcome of a coin toss." << std::endl
        << "You can only bet as much as you have." << std::endl;
 
    game();
 
    return 0;

TFW we’re just porting to different languages.

I went a bit overboard.

Hey @Defalt! Nice to have you back!
Also, there’s no such thing as overboard…


(oaktree) #7

Lol exception handling. That could be considered “overboard.”


#8

Also, great code @Defalt, might change my own based on yours.
You can really see the difference between a beginner/intermediate (me) and an advanced coder like yourself!


(The Defalt) #9

Thank you for the compliment. It means a lot to me.

#! /usr/bin/ruby

$balance = 100

def flipCoin(bet, predict)
	    if ((bet == 0) or (bet > $balance))
		    puts '[!] Invalid Bet!'
		    return
	    end
	    return if (predict != 'heads' and predict != 'tails')
	    result = Random.new().rand(2)
	    if ((result == 0 and predict == 'heads') or (result == 1 and predict == 'tails'))
		    puts '[*] You won!'
		    $balance += bet*2
	    else
		    puts '[*] You lost!'
		    $balance -= bet
	    end
end

def getBet()
	    begin
		    print "[*] Enter Bet: "
		    bet = gets.chomp.to_i
		    print "[*] Heads or Tails: "
		    predict = gets.chomp.downcase		
		    return [bet, predict]
	    rescue
	    end
end

while true
	    print "Menu:\n1. Play\n2. Check Balance\n3. Exit\n"
	    print "> "
 	    choice = gets.chomp
	    begin
		    case choice
		    when "1"
			    userBet = getBet()
			    flipCoin(userBet[0], userBet[1])
		    when "2"
			    puts "[*] Balance: #{$balance}"
		    when "3"
			    exit
		    end
	    rescue
	    end
end

I got bored so here it is in Ruby.
