Description
int rand ([int min [, int max]])
If called without the optional min,
max arguments rand()
returns a pseudo-random value between 0 and
RAND_MAX. If you want a random number
between 5 and 15 (inclusive), for example, use rand (5,
15).
Remember to seed the random number generator before use with
srand().
Note:
In versions before 3.0.7 the meaning of
max was range. To
get the same results in these versions the short example should
be rand (5, 11) to get a random number
between 5 und 15.
See also srand(),
getrandmax(), mt_rand(),
mt_srand(), and
mt_getrandmax().
