Sets the starting seed value for the pseudorandom number generator.
void srand(
unsigned int seed
);

Seed for pseudorandom number generation
The 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 srand
with seed
passed as 1.
