NAME

std::mersenne_twister_engine::seed - std::mersenne_twister_engine::seed

Synopsis

void seed( result_type value = default_seed ); (1) (since C++11)
template< class Sseq > (2) (since C++11)
void seed( Sseq& seq );

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
