/*hi I'm having problems with my "while ()" apperently it is not taking any action, and it keeps going endless. i need it to stop when the answer is 'n'*/

thanks i just notice like a minute ago after i posted, thanks majestics

Unportable code alarm!
You're including conio.h, this isn't a standard library file
iostream.h is not a C header, it's a C++ header, so you posted your code in the wrong forum
Aaargh, the terrible void main() , it's evil, replace it with int main() (read this ).
This is not C code, this is C++ code (this means that you've posted in the wrong forum), consider using new style header files (if your compiler supports it), so:

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
#include<string.h>
#include<iostream.h>

would become:

#include<cstdio>
#include<conio.h>
#include<cstdlib>
#include<cstring>
#include<iostream>

:)

Note: This is definitely (rubbish) C++ code (mixed with C), cout is an object, and C isn't an object oriented language :P

gawd yes, what a mess. i too hate conio.

It's pretty much logical your while statement isn't working correctly, if you use the '=' operator in an expression, this means that you're assigning something, it means not that you're comparing something, if you want to compare, you should use the '==' operator so while (r[B]=[/B]'s') would become while (r[B]==[/B]'s') :)
