What is std::auto_ptr in C++11?

Can you explain what std::auto_ptr is in C++11?

std::auto_ptr is a smart pointer that manages the lifetime of dynamically allocated objects. It was deprecated in C++11.

Why was std::auto_ptr deprecated?

It was deprecated because it has unsafe ownership semantics, leading to potential issues with object ownership and memory leaks.

What should I use instead of std::auto_ptr?

You should use std::unique_ptr or std::shared_ptr, which provide better ownership semantics and are safer to use.

Can you give me an example of using std::unique_ptr?

Sure! Here's a simple example: std::unique_ptr<int> ptr(new int(10)); This creates a unique pointer managing an integer.
