What are the new raw pointer safety features in C++11?

C++11 introduced several features to enhance raw pointer safety, including smart pointers like std::unique_ptr and std::shared_ptr.

How do smart pointers improve safety compared to raw pointers?

Smart pointers automatically manage memory, reducing the risk of memory leaks and dangling pointers that are common with raw pointers.

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

Sure! Here's a simple example:

#include <memory>

std::unique_ptr<int> ptr(new int(10));
// ptr will automatically delete the allocated memory when it goes out of scope.

What are the limitations of using smart pointers?

Smart pointers can introduce overhead and may not be suitable for all scenarios, especially in performance-critical code.
