Non-copyable and Non-copy-constructable. I prefer to deal with smart pointers:

 std::vector<std::unique_ptr<value>> v;  for (int i=0; i<10; i++)   v.emplace_back(new value(7)); 

Write a move constructor and then use emplace_back:

struct value { ... value(value && obj) : i_(obj.i_) { } or value(value && obj) = default; ... }; std::vector<value> v; for (int i=0; i<10; i++) v.emplace_back(7);
