Do you have a reason for posting all that code ???

[Tashandra]

Hi,

I'm new to the IT world and was wondering what the code is for? Is it a game or a pic. or what?

[jephthah]

who knows? and more importanly, who cares?

the OP didn't bother describing anything, so i'm not going to bother trying cipher out the code. Or trying to read his mind.

the fact that he uses <conio.h> does tells me it's probably a broken, unportable mess, and I just stopped looking at it right there.

[Ancient Dragon]

I'd suggest the OP compile the code then run it to see what it does.

[mvmalderen]

What I guess is that the name "my code" is not a very appropriate name for this thread, because the OP probably didn't even write this code himself.
But who knows? Only the OP, right?
But if he just drops down his code on forum, without any comments, then he's just begging for replies like this one.
If he did, then I strongly suggest him to read the following guide, whatever error or bug there is in his code, this will help to prevent nearly any of them: http://cboard.cprogramming.com/c-programming/88495-development-process.html (follow these guidelines when designing/creating/writing a new program).
I also want to suggest the OP to read this: How to ask questions the smart way.
