What are some unique use cases for std::unique_ptr in C++?

std::unique_ptr is great for managing dynamic memory. One unique use case is implementing a custom deleter for resource management.

Can you give me an example of a custom deleter?

Sure! You can use a lambda function as a custom deleter to close file handles when the unique_ptr goes out of scope.

That sounds useful! Are there any performance benefits?

Yes, using std::unique_ptr can reduce memory leaks and improve performance by ensuring timely resource deallocation.

What about using std::unique_ptr with arrays?

You can use std::unique_ptr with arrays by specifying the array type, like std::unique_ptr<int[]> for dynamic integer arrays.
