rand, srand − random number generator
srand(seed)
int seed;
rand( )
Rand uses a multiplicative congruential random number generator with period 2 32 to return successive pseudo-random numbers in the range from 0 to 2 15 −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.
