Sets the starting seed value for the pseudorandom number generator.
void srand( unsigned int seed );
Seed for pseudorandom number generation
srand function sets the starting point for generating a series of pseudorandom integers in the current thread. To reinitialize the generator to create the same sequence of results, call the
srand function and use the same
seed argument again. Any other value for
seed sets the generator to a different starting point in the pseudorandom sequence.
rand retrieves the pseudorandom numbers that are generated. Calling
rand before any call to
srand generates the same sequence as calling
seed passed as 1.
