I'm afraid is not. See below.

For this piece of source code, 'random' is the least of your
problems. AFAIK, there is not conio.h available for *nix. So no
'gotoxy' and other DOS console functions. You could use the "curses"
library, which is far more complete than conio.h, but more complex
as well.

OTOH, take a look at the ISO C functions 'rand', 'random', and
'srand'.
