What are the advanced features of std::unique_ptr in C++?

std::unique_ptr offers features like custom deleters, move semantics, and support for arrays. Would you like to know more about any specific feature?

Can you explain how custom deleters work?

Sure! Custom deleters allow you to define how the memory is released when the unique_ptr goes out of scope. You can pass a function or a lambda as a deleter.

What are some use cases for using std::unique_ptr with custom deleters?

Use cases include managing resources like file handles or network connections, where you need specific cleanup logic.

How does std::unique_ptr handle move semantics?

std::unique_ptr cannot be copied, but it can be moved. This means you can transfer ownership of the managed object to another unique_ptr.
