How can I prevent memory leaks in C++ using the Standard Library?

To prevent memory leaks in C++, you can use smart pointers like std::unique_ptr and std::shared_ptr, which automatically manage memory.

Can you explain how std::unique_ptr works?

Sure! std::unique_ptr is a smart pointer that owns a dynamically allocated object and ensures that it is deleted when the unique_ptr goes out of scope.

What happens if I try to copy a std::unique_ptr?

You cannot copy a std::unique_ptr because it is designed to have a single owner. If you need to transfer ownership, you can use std::move.

Are there any other tools in the Standard Library to help with memory management?

Yes, you can also use std::shared_ptr for shared ownership and std::weak_ptr to avoid circular references.
