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
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
