NAME
rand, srand - random number generator
SYNOPSIS
srand(seed) int seed;rand()
DESCRIPTION
The newer random(3) should be used in new applications;
rand remains for compatibilty.
Rand uses a multiplicative congruential random number generator with period 2\u\s732\s0\d to return successive pseudo-random numbers in the range from 0 to 2\u\s731\s10\d-1.
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.
