i need store sequence of elements of type thirdpartyelm , , i'm using std::vector (or std::array if need fixed size sequence). i'm wondering how should initialise sequence. first version creates new element , (if i'm right) creates copy of element when inserted in sequence: for (int = 0; < n; i++) { auto elm = thirdpartyelm(); // init elm.. my_vector.push_back(elm); // my_array[i] = elm; } the second version stores sequence of pointers (or better smart pointers c++11): for (int = 0; < n; i++) { std::unique_ptr<thirdpartyelm> elm(new thirdpartyelm()); // init elm.. my_vector.push_back(std::move(elm)); // my_array[i] = std::move(elm); } which lightweight version? please highlight errors. avoid dynamic allocation whenever can. thus, prefer saving elements instead of smart-pointers them in vector. that said, either fine, , if thirdpartyelem polymorphic, wouldn't have choice. other considerations cost , possibil...
