[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
