What are the different types of smart pointers in C++?
An example of an AI chatbot conversation about C++ smart pointers and their types.
What are the different types of smart pointers in C++?
In C++, there are three main types of smart pointers: std::unique_ptr, std::shared_ptr, and std::weak_ptr. Would you like to know more about each?
Yes, please explain std::unique_ptr.
std::unique_ptr is a smart pointer that owns a dynamically allocated object exclusively. It cannot be copied, only moved, ensuring that there is a single owner of the resource.
What about std::shared_ptr?
std::shared_ptr allows multiple smart pointers to share ownership of a single object. It keeps a reference count to manage the lifetime of the object.
And what is std::weak_ptr used for?
std::weak_ptr is used to break circular references in shared_ptr. It does not contribute to the reference count, allowing the object to be deleted when no shared_ptrs point to it.
