i have a question concerning a part of the code from the allegro example
files.  it's probably a stupid question but i've looked in my c and c++
books and i can't find the answer.  here's the question, in this small
snippet of the code..

      hotspot[c] += (random() & 7) - 3;

what does "random() & 7" do?  i'm figuring random() returns a random
# of type int maybe?  but i have no idea what the "& 7" does.  the & 7
is the only thing that i need an explenation for.  any help would be
much appreciated.

Daniel
