at the beginning of your main program, put the following:

srand(time(0));

and don't forget at beginning of the same file:

#include <stdlib.h>
#include <time.h>

This works for me. srand(time(0)) takes the current time and seeds the
random numbers generator with it. After that, you can use rand() to
get a series of pseudo-random numbers (depending on the seed value
used with srand())
