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

NAME

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
