// random_device example
#include <iostream>
#include <random>
int main ()
{
std::random_device rd;
std::cout << "default random_device characteristics:" << std::endl;
std::cout << "minimum: " << rd.min() << std::endl;
std::cout << "maximum: " << rd.max() << std::endl;
std::cout << "entropy: " << rd.entropy() << std::endl;
std::cout << "a random number: " << rd() << std::endl;
return 0;
}

可能的输出
default random_device characteristics:
minimum: 0
maximum: 4294967295
entropy: 32
a random number: 4230014324
