DESCRIPTION

|
Rand uses a multiplicative congruential random number generator with
|

period 2**32 to return successive pseudo-random numbers in the range from
|
|
0 to RAND_MAX.
|
|
|
|
The generator is reinitialized by calling srand with 1 as argument. It
|
|
can be set to a random starting point by calling srand with whatever you
|
|
like as argument.
