What are advanced techniques for using smart pointers in C++?

Advanced techniques for using smart pointers include custom deleters, shared pointers with weak pointers, and using smart pointers in data structures.

Can you explain how to use custom deleters with smart pointers?

Sure! You can define a custom deleter by passing a lambda function or a function pointer to the smart pointer's constructor.

What are the benefits of using weak pointers?

Weak pointers help prevent circular references in shared pointers, allowing for better memory management and avoiding memory leaks.

Are there any performance considerations when using smart pointers?

Yes, while smart pointers manage memory automatically, they can introduce overhead due to reference counting, so it's important to use them judiciously.
