まず C++ で STL。 #include <vector> #include <iostream> int main(){ std::vector<int> u, v; std::vector<std::vector<int>*> m; m.push_back(&u); m.push_back(&v); for(int i = 0; i < 5; i++){ u.push_back(i); v.push_back(-3 * i); } u[4] = 100; v[2] *= -1; for(std::vector<std::vector<int>*>::iterator m</std::vector<int></std::vector<int></int></iostream></vector>…
