Library Functions
RAND
Synopsis
Description
The rand() function is a pseudo-random number generator. It returns an integer in the range 0
to 32767, which changes in a pseudo-random fashion on each call. The algorithm will produce a
deterministic sequence if started from the same point. The starting point is set using the srand() call.
The example shows use of the time() function to generate a different starting point for the sequence
each time.
