void reseed(); | (1) | (library fundamentals TS v2) |
void reseed( std::default_random_engine::result_type value); | (2) | (library fundamentals TS v2) |
Reseeds theper-thread random number engine and anystd::uniform_int_distribution instances used byrandint.
g as if byg.seed(value).Contents |
| value | - | value of the new seed |
Subsequent calls torandint do not depend on values produced by the per-thread engine prior to callingreseed.
#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
| generates a random integer in the specified range (function template)[edit] |
