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

Sets the state of the random-number engine.

1) Right after the state is set, *this == std::mersenne_twister_engine(value) is true.
2) Right after the state is set, *this == std::mersenne_twister_engine(seq) is true.

Parameters

value - seed value to use to set the state
seq - seed sequence to use to set the state

Exceptions

Throws nothing.

Complexity

1) Same as std::mersenne_twister_engine(value).
2) Same as std::mersenne_twister_engine(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
