From cppreference.com
< cpp | numeric | random | 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
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
