std::mersenne_twister_engine<UIntType,w,n,m,r,a,u,d,s,b,t,c,l,f>::seed
void seed( result_type value = default_seed ); | (1) | (since C++11) |
template< class Sseq > void seed( Sseq& seq ); | (2) | (since C++11) |
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).
Complexity
Example
#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
