Exemple
#include <random>
#include <sstream>
#include <iterator>
int main()
{
std::seed_seq s1; // default-constructible
std::seed_seq s2{1, 2, 3}; // can use list-initialization
std::seed_seq s3 = {-1, 0, 1}; // another form of list-initialization
int a[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
std::seed_seq s4(a, a + 10); // can use iterators
std::istringstream buf("1 2 3 4 5");
std::istream_iterator<int> beg(buf), end;
std::seed_seq s5(beg, end); // even stream input iterators
