Synopsis

void seed(result_type value = default_seed);
(1)(since C++ 11)

    template <class Sseq>

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
