It always makes an annoying "BEEP!" when it shows the board. (It cout's the board after TopOfLoop:) All help is appreciated :)

Ok, well before I give you any solid help I need to find out some information first…what program are you using to develop the C++ code? Is it Visual Studio 6? 2005? Dev C++?
I'm pretty good with VS 2005, and I remember a little bit of VS 6…I'm not that good with Dev C++, but I can make it work =P.
Just let me know and I'll make an edit on this post with some fixes =)
For now I'll try working with it in VS 2005

EDIT: Alright, I admit this is pretty weird. I can't find the source of the beep. Nice job on the code btw :)!
Anyway, I'm not sure if you've noticed this, but I found that if you start at a higher number, such as inputing 8 or 9 first, the beeps go away. If you try to start with anything before that the beeps continue until one of those numbers are pressed.
I can't, for the life of me, figure out why the computer thinks that it needs to beep if the number is less than 8. I'll try working with it for a little while longer, and I'll add some more edits to this post of I fix it.

Weirdest non-syntax error ever :p

tvXxX is good at that he makes an game ask him

Microsoft Visual C++ 2005 Express Version. Thanks for checking it out for me. :D

Yes, it is the wierdest nonsyntax error ever. XD

Just a tip: get rid of the using std:: crap at the top there. You don't need it. Not a good practice to use namespaces either. Just call your cin/cout functions like this:

std::cout << "lol" << std::endl;

Easy.

Second thing, don't use explicit arrays. Use the std::vector template container class. You can access it like an array but it's WAYYY better. It can be used in a dynamic way. Seriously. Example: to declare an int array:

std::vector<int> myArray;

Or a boolean array:

std::vector<bool> anotherArray;

Yet another tip: don't use char arrays. Use the string class std::string.

Uhm… Its back? OMFG! ITS BAAAAACCCCCKKKKK!!!

But it taught me something… something I will not forget ;)




But if I didn't need all of the extra… things …that vectors have, why use one?

1. What's back?
2. An array in C++ is very messy. It's just an array of pointers. That's why just use vectors. Trust me, they'll come in handy. That's the C++ way of doing things.

Err, unfortunately, I think he's talking about you. :redface:

Lol.

Anyway, best site for C++ stuff: http://www.cplusplus.com/doc/tutorial/

And here's a simple program I made to demonstrate the use of the std::vector class exactly like an array: http://www.blog.solarwind.metafy.org/2008/02/21/c-random-number-guesser-alpha/
