Example

// Run this code


#include <iostream>
#include <random>


int main()
{
std::mt19937 gen;


// Seed the engine with an unsigned int
gen.seed(1);
std::cout << "after seed by 1: " << gen() << '\n';


// Seed the engine with two unsigned ints
std::seed_seq sseq{1, 2};
gen.seed(sseq);
std::cout << "after seed by {1,2}: " << gen() << '\n';
}

Possible output:


after seed by 1: 1791095845
after seed by {1,2}: 3127717181
