"Craps", Game Help

  #1
Sep 26th, 2004
I've been studying VC++ for about 2 months, and I was working on my first game from a book (Game Programming All In One)
The game is 'Craps', it's a dice game. Anyways, I've had a few prolems with the codeing, can someone help me? (Windows 32 Console)
Here is the game....


Code:
C++ Syntax (Toggle Plain Text) 
  1. #include <iostream>                                        // Includeing Headers

I've had a few problems with this book already, it's about 2 years old or so, it uses an older version of c++ and there has been some
modifications over those few years. ANYWAYS!!! I need help, here are the errors!


c:\Projects\Craps\Craps.cpp(151): error C2065: 'MoneyEarned' : undeclared identifier
c:\Projects\Craps\Craps.cpp(95): error C2601: 'DoDiceThrow' : local function definitions are illegal
c:\Projects\Craps\Craps.cpp(123): error C2601: 'DoMoneyCalc' : local function definitions are illegal
c:\Projects\Craps\Craps.cpp(26): warning C4244: '=' : conversion from 'unsigned long' to 'short', possible loss of data

Well I got it to compile and run.

Here's the errors that I found:

Your function prototypes didn't match the function's return type in it's code. (Aka, return a short but prototype says it returns void.)

You didn't close all functions with braces. Forgot a few :-P

You closed the switch statement with a brace but didn't open with one.

Other than that it's all good. One thing that I would change, not bad code just style, is to not use tab in the parameter list of a function and don't use it inside strings unless needed.

Here's the output from the console and I think you'll see what I mean about tabs in strings. It makes it hard to read.
C++ Syntax (Toggle Plain Text) 
  1.           Welcome to Craps 1.0
  2.  
  3.  Here are the rules:
  4.  
  5. You have 1000 dollars to start  gambling.
  6.  
  7. There are three types of bets.  You     can     bet     on:
  8.  
  9.   - 2 and 12 which      will give you the ratio of 5 to 1 if you win.
  10.   - 4 and 10 which      will give you the ratio of 2.5 to 1     if you win.
  11.   - 6 and 8 which will  give you the ration     of 1.5 and 1 if you     win.
  12.  
  13. The minimum amount      of money you can bet is 10 dollars and
  14.  the highest amount     of money you can bet is 100.
  15.  
  16. Have fun playing!
  17.  
  18. You have :      1000    dollars.
  19.  
  20. Enter a type of bet ( 1 = '6/8',  2 = '4/10',   3 =     '2/12':

Other than that, nice job overall!

Here's the revised code:

Thanks! ^^ I'm still having some issues with it, but it was just a test!
