I have copied this program from this site, and simply copied as a new C++ file
but when run I got a number of error. so I included Myheader file which amongs other includes, the iostream.h, and stlib.h, that is why they have been commented out below. Any way doing this I have then run the program, and got a syntax error so I commented out line six as well, as shown below, but then still couldn't get the program to run, I keep getting this error

I think you should comment out the first line.

[B]//#include"myheader.h"[/B]
#include<iostream.h>
#include<time.h>
#include<stdlib.h>
#include<windows.h>
...

yes that's exactly the error have got.

once i comment the first line, I get loads more errors.

Am guessing maybe that game is rather a C++ project, but i have tried creating it as a project but still no success. Uhh I don't know

can smeone please try and copy the game from http://www.daniweb.com/techtalkforums/thread5123.html
and see if you can get it to work.

Thank you
