What are the best practices for using std::unique_ptr in C++?

When using std::unique_ptr, always prefer it over raw pointers for better memory management. Make sure to use it for exclusive ownership.

Can you explain how to transfer ownership of a unique_ptr?

You can transfer ownership of a std::unique_ptr using std::move. This will transfer the pointer to another unique_ptr.

Are there any situations where I shouldn't use unique_ptr?

Yes, avoid using std::unique_ptr when you need shared ownership. In such cases, consider using std::shared_ptr instead.

What happens if I try to copy a unique_ptr?

Copying a std::unique_ptr is not allowed and will result in a compilation error, as it is designed for unique ownership.
