  10. I know what the c.l.c. FAQ says about pseudo-random numbers, so I wonder why
  11. I seem to get "better" results with "rand() % n + 1" than I get when I use
  12. "n * rand() / RAND_MAX + 1"  Am I missing some parenthesis or something?
  13. Oh yeah, and I usually call "srand(clock())" once in the initialization of
  14. my program.  With the first, I get an integer between 1 and n.  With the
  15. second, I almost always get a value of 1 or 2.
