std::binomial_distribution<IntType>::param – std::binomial_distribution<IntType>::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
