C++ smart vector with smart pointers?

Question

Learning smart pointers and stumble upon this problem: How would I create a vector with objects that auto deletes themselves? Below is a snippet of how I have it at the moment, is this the correct way to ensure I don't need to call delete on anything?

unique_ptr<vector<unique_ptr<OBJ>>> list(new vector<unique_ptr<OBJ>>);

Answer 1

H.Guijt指出了在向量本身上调用new的冗余，下面的代码应该足够了：

vector<unique_ptr<Entry>> list;
