    Craps Game

    Heres my first really c++ game that I did some functions and stuff in. I'm just starting to program reading an eBook I downloaded. Please feel free to leave comments or suggestions.

    Code:
    /********************

    *	Craps Game
    *	main.cpp

    short playerBet (void);
    short diceRoll (void);
    unsigned short moneyCalc (short diceValue, short getBet, short betMoney);
    unsigned long getAmount (void);
    
    
    int main ()
    {
    	unsigned long playerEarned;
    	unsigned long playerMoney;

    		betMoney     =   getAmount ();
    		diceValue    =   diceRoll ();
    		playerEarned =   moneyCalc (diceValue, getBet, betMoney);
    
    		playerMoney -= betMoney;

    Howdy,
    definitely a great place to start. I don't have experience playing the real gambling game, but I did play this for a few minutes. It looks like a real good start, keep up the good work!

    And sure, I'll send some good reputation your way

    You have two warnings you know
    Code:
    playerEarned = betMoney * 1.5;
    should be
    Code:
    playerEarned = betMoney * (unsigned)1.5L;
    and with
    Code:
     playerEarned = betMoney * 2.5;
    should be
    Code:
     playerEarned = betMoney * (unsigned)2.5L;
    Plus
    Why does g++ say that UL is an invalid suffix?
    Unsigned constants are written with a terminal u or U, and the suffix ul or UL indicates unsigned long.

    2.5 is not a long it is a double. You want to cast the result and not the individual numbers. IE
    Code:
     playerEarned = (unsigned long)(betMoney * 2.5);
    Oh any my copy of g++ has no problems with UL.

    @TWIXMIX: You need to provide a gracious way to end the game early.
