std::experimental::reseed

From cppreference.com
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).

Contents

[edit] Parameters

value - value of the new seed

[edit] Remarks

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

[edit] Example

#include <experimental/random>
#include <iostream>
 
auto main() -> int
{
    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
