### Smart pointers
C++11 introduces new smart(er) pointers: `std::unique_ptr`, `std::shared_ptr`, `std::weak_ptr`. `std::auto_ptr` now becomes deprecated and then eventually removed in C++17.
C++11 introduces new smart pointers: `std::unique_ptr`, `std::shared_ptr`, `std::weak_ptr`. `std::auto_ptr` now becomes deprecated and then eventually removed in C++17.
`std::unique_ptr` is a non-copyable, movable smart pointer that properly manages arrays and STL containers. **Note: Prefer using the `std::make_X` helper functions as opposed to using constructors. See the sections for [std::make_unique](#stdmake_unique) and [std::make_shared](#stdmake_shared).**
`std::unique_ptr` is a non-copyable, movable pointer that manages its own heap-allocated memory. **Note: Prefer using the `std::make_X` helper functions as opposed to using constructors. See the sections for [std::make_unique](#stdmake_unique) and [std::make_shared](#stdmake_shared).**
```c++
std::unique_ptr<Foo> p1 { new Foo{} }; // `p1` owns `Foo`
