What are some common mistakes when using unique_ptr in C++?

What are some common mistakes when using unique_ptr in C++?

Some common mistakes include not using unique_ptr for resource management, forgetting to release ownership, and using it with raw pointers.

Can you explain why forgetting to release ownership is a mistake?

Forgetting to release ownership can lead to memory leaks, as the unique_ptr will not free the resource when it goes out of scope.

What happens if I try to copy a unique_ptr?

Attempting to copy a unique_ptr will result in a compilation error, as unique_ptr is designed to have exclusive ownership.

Are there any scenarios where using unique_ptr is not recommended?

Yes, using unique_ptr is not recommended in scenarios where shared ownership is required; in such cases, consider using shared_ptr.
