NAME¶

std::binomial_distribution::param - std::binomial_distribution::param

Synopsis¶

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

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
