What are some use cases for unique_ptr in C++?

Unique_ptr is used for managing dynamic memory, ensuring that there is a single owner for a resource.

Can you give me an example of when to use unique_ptr?

Sure! Use unique_ptr when you want to manage the lifetime of an object without worrying about memory leaks.

How does unique_ptr differ from shared_ptr?

Unique_ptr allows only one owner, while shared_ptr allows multiple owners to share the same resource.

Are there any performance benefits to using unique_ptr?

Yes, unique_ptr has lower overhead compared to shared_ptr since it doesn't require reference counting.

When should I avoid using unique_ptr?

Avoid using unique_ptr when you need shared ownership or when the resource needs to be passed around multiple times.
