What are some advanced usage scenarios for unique_ptr in C++?

Unique pointers are great for managing dynamic memory. One advanced usage is implementing custom deleters.

Can you explain how to use custom deleters with unique_ptr?

Sure! You can pass a custom deleter as a second argument to unique_ptr, allowing you to define how the memory is released.

What are some practical examples of custom deleters?

For instance, if you're managing resources like file handles or network connections, you can create a deleter that properly closes them.

Are there any performance considerations when using unique_ptr?

Yes, using unique_ptr can improve performance by avoiding memory leaks and ensuring proper resource management, but be mindful of the overhead of custom deleters.
