What are the key features of memory management in the C++ Standard Library?

The C++ Standard Library provides several features for memory management, including smart pointers like std::unique_ptr and std::shared_ptr, which help manage dynamic memory automatically.

Can you explain how std::unique_ptr works?

Sure! std::unique_ptr is a smart pointer that owns a dynamically allocated object and ensures that it is deleted when the unique_ptr goes out of scope. It cannot be copied, only moved.

What are the advantages of using smart pointers over raw pointers?

Smart pointers help prevent memory leaks and dangling pointers by automatically managing the memory lifecycle, making your code safer and easier to maintain.

Are there any performance considerations when using smart pointers?

Yes, while smart pointers add some overhead due to reference counting and additional checks, they often lead to better overall performance by reducing memory management errors.
