std::mersenne_twister_engine<UIntType,w,n,m,r,a,u,d,s,b,t,c,l,f>::seed: std::mersenne_twister_engine<UIntType,w,n,m,r,a,u,d,s,b,t,c,l,f>::seed

NAME

std::mersenne_twister_engine<UIntType,w,n,m,r,a,u,d,s,b,t,c,l,f>::seed - std::mersenne_twister_engine<UIntType,w,n,m,r,a,u,d,s,b,t,c,l,f>::seed

Synopsis

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

Reinitializes the internal state of the random-number engine using new seed value.

Parameters

value - seed value to use in the initialization of the internal state
seq - seed sequence to use in the initialization of the internal state

Exceptions

(none)

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
