If you do this, it may make debugging more difficult, since the program won't behave the same way twice. However:

srand( (unsigned)time( NULL ) );

That will seed the standard random number generator with your system time. Do this once only, as your program starts up.

Then, you can call rand() to return to you a new random number between 0 and RAND_MAX.
