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) << ' ';
std::cout << '\n';
}
Possible output:
Random 2-digit decimal numbers: 41 60 56
