Hello all.  Well I am trying to generate some random "dice" rolls with rand
and I am having difficulty.  I have #include <time.h> so that I can use
srand(time(NULL)); to generate a new seed each time but the problem is when
I roll a d6 for example it rolls it and will keep generating the same number
each time the program is run.  Here is what I am talking about:

#include <time.h>

~~~skipping main and stuff~~~
int die;

srand(time(NULL)); got this out of my c++ book to use the seconds to
generate a "seed"

die = ((rand%6)+1);
die = ((rand%6)+1);
die = ((rand%6)+1);
die = ((rand%6)+1);

when I run this each time i run it I get a different number but all four of
them are the same.  For example...
first run
die = 2
die = 2
die = 2
die = 2

second run
die = 5
die = 5
die = 5
die = 5

Could anyone help me generate more random numbers in my code?  Thanks in
advance.

Will
