std::mersenne_twister_engine::seed

STD：Mersenne[医]捻线机[医]发动机：：种子

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

使用新的种子值重新初始化随机数引擎的内部状态。

参数

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

例外

例

二次

#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';
}

二次

可能的产出：
