You can not use any function in the conio.h in Windows programs. This header is obsolete and most of the functions are only usable in "real" DOS.

Undefined reference is a linker error. You need to link against whatever static library defines delay(). Unfortunately, after Googling, I have no idea what library that would be. Try sleep? Sleep is defined in <unistd.h>
Thank you for your kind reply. The "sleep()" function under <dos.h> is working nicely also the "Sleep()" under <windows.h> is working. may be u are right, the delay() function will not work under windows 7.

Glad to help. If you'd ever like to try Linux development, things are relatively standard, and as far as I know, you won't find broken API stuff like this. Ubuntu is a pretty good distribution. I recommend it. You can also play Starcraft II on it just fine.
I think you mean <dos.h>, not <conio.h>. I use getch() from <conio.h> in Windows just fine.Originally Posted by jimblumberg

@cpjust you are correct, but dos.h and conio.h are considered obsolete....
