[edit]Example
Run this code
#include <iostream>#include <random> int main(){std::random_device rd;std::mt19937 gen(rd());using BinomialDist =std::binomial_distribution<>; BinomialDist bino_dis(1, 0.5); std::cout<<"A sample of Binomial( 1, 0.5): "<< bino_dis(gen)<<'\n'; // Use another parameter set bino_dis.param(BinomialDist::param_type(100,0.9));std::cout<<"A sample of Binomial(100, 0.9): "<< bino_dis(gen)<<'\n';}
Possible output:
A sample of Binomial( 1, 0.5): 0 A sample of Binomial(100, 0.9): 94
