geometric_distribution::p
傳回由發出參數。
RealType p() const;
備註
成員函式會傳回已儲存的值 stored_p。
範例
// std_tr1__random__geometric_distribution_p.cpp
// compile with: /EHsc
#include <random>
#include <iostream>
typedef std::mt19937 Myeng;
typedef std::geometric_distribution<int, double> Mydist;
int main()
{
Myeng eng;
Mydist dist(0.1);
Mydist::input_type engval = eng();
Mydist::result_type distval = dist(eng);
distval = distval; // to quiet "unused" warnings
engval = engval;
std::cout << "p == " << dist.p() << std::endl;
dist.reset(); // discard any cached values
std::cout << "a random value == " << dist(eng) << std::endl;
std::cout << "a random value == " << dist(eng) << std::endl;
std::cout << "a random value == " << dist(eng) << std::endl;
return (0);
