srand

Sets a random starting point.

void srand(
   unsigned int seed 
);

seed

Seed for random-number generation

The srand function sets the starting point for generating a series of pseudorandom integers in the current thread. To reinitialize the generator, use 1 as the seed argument. Any other value for seed sets the generator to a random starting point. rand retrieves the pseudorandom numbers that are generated. Calling rand before any call to srand generates the same sequence as calling srand with seed passed as 1.
