std::binomial_distribution::param

性病：：二项式[医]分配：：Param

param_type param() const;(1)(since C++11)
void param( const param_type& params (2)(since C++11)

管理关联的分发参数集。

1%29返回相关的参数集。

2%29将相关参数设置为params...

参数

params-new contents of the associated parameter set

返回值

1%29相关联的参数集。

2%29%28%29。

复杂性

常量。

例

二次

#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';
}

二次

可能的产出：

二次
