Hi Rick
Thanks for the link! I definitely need a good
understanding of OOP and that link will certainly
help.
anyway, other than that, I need a function which will
randomly return either -1 or 1 (but not zero). I 've
been thinking about that the whole night but cant seem
to be able to do it :(
Can anyone help me about that?
Cheeers!
jonathan.
