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
#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
