What is the reason that C++11 gives up auto_ptr? [duplicate]

Question

It gives up auto_ptr and adds unique_ptr and shared_ptr. Are they good enough to let c++ abandon auto_ptr? There must be sometimes auto_ptr could lead to bad results. Can anyone give me an example?

If it doesn't do bad C++11 will keep it rather than give up.

Answer 1

Because unique_ptr is a better alternative for auto_ptr.

In particular, it was not possible to store an auto_ptr in a container. While you can store unique_ptr in a container.
