std::shuffle(std::begin(cards_), std::end(cards_), rng); 随机本来是挺简单的,日常大家的做法是rand()%n,即可得到一个n范围内的变量,来自行随机,但实际的效果没有std实现的随机好,实在想用的话,使用创建std::vector集合来实现随机吧
int main() { printf("vec size:%lu; set size:%lu\n",sizeof(std::vector<uint32_t>),sizeof(std::set<uint32_t>)); std::random_device rd; std::mt19937 mt(rd()); std::shuffle(V.begin(),V.end(),mt); for(size_t i=0;i<V.size();++i) {ST.insert(V[i]);} for(auto ...
但我不明白我应该如何实现 random_engine 函数。我所做的与 std::random_shuffle 配合得很好,但我知道这个函数已被弃用,而 std::shuffle 是首选。我正在努力让它发挥作用:int main() { std::vector<int> v = { 1, 2, 3, 4, 5, 6, 7, 8, 9 }; std::shuffle (v.begin(), v.end(), my...
std::vector<int> v; for (int i = 0; i < 10; ++i) { v.push_back (i); } // obtain a time-based seed: unsigned seed = std::chrono::system_clock::now ().time_since_epoch ().count (); std::shuffle (v.begin (), v.end (), std::default_random_engine (seed)); for (...
