NAME¶

std::experimental::reseed - std::experimental::reseed

Synopsis¶

Defined in header <experimental/random>
void reseed(); (1) (library
fundamentals TS v2)
void reseed(std::default_random_engine::result_type value); (2) (library
fundamentals TS v2)

Reseeds the per-thread random number engine and any std::uniform_int_distribution
instances used by randint.

1) Sets the per-thread engine to an unpredictable state.
2) Seeds the per-thread engine g as if by g.seed(value).

Parameters¶

value - value of the new seed

Remarks

Subsequent calls to randint do not depend on values produced by the per-thread
engine prior to calling reseed.

Example¶

// Run this code

#include <experimental/random>
#include <iostream>

int main()
{
std::experimental::reseed();

std::cout << "Random 2-digit decimal numbers: ";

for (auto i = 0; i != 3; ++i)
{
std::cout << std::experimental::randint(10, 99) << ' ';
}
}

Possible output:¶

Random 2-digit decimal numbers: 41 60 56
