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

Using unique_ptr is great for managing dynamic memory. Always prefer it over raw pointers to avoid memory leaks.

Can you explain how to transfer ownership with unique_ptr?

Sure! You can transfer ownership using std::move. For example, if you have a unique_ptr named ptr, you can transfer it like this: unique_ptr<YourType> newPtr = std::move(ptr);

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

Yes, if you need shared ownership, consider using shared_ptr instead. Also, avoid using unique_ptr for non-heap objects.

What about using unique_ptr with arrays?

You can use unique_ptr with arrays by specifying the array type: unique_ptr<Type[]> ptr(new Type[size]); This ensures proper deletion.
