std::experimental::reseed(3) | C++ Standard Libary | std::experimental::reseed(3) |
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) << ' ';
std::cout << '\n';
}
Possible output:¶
Random 2-digit decimal numbers: 41 60 56
