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

Manages the associated distribution parameter set.

1) Returns the associated parameter set.
2) Sets the associated parameter set to params .

Contents

Parameters

params - new contents of the associated parameter set

Return value

1) The associated parameter set.
2) (none)

Complexity

Constant.

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
