@Gordon: rand() and srand() are defined in stdlib. You can find out about any standard function with the man command in the Terminal. So you could type "man srand" and it would tell you:
NAME
rand, srand, sranddev, rand_r -- bad random number generator
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include
...followed by a whole bunch more information about what the functions do and how they're used.
By the way, random() and srandom() are better for getting random numbers (which is why the manpage for rand() says it's a "bad random number generator"). rand() and srand() are mainly there for compatibility.
