An example of an AI chatbot conversation about when to use smart pointers in C++.
When should I use smart pointers in C++?
Smart pointers are used in C++ to manage dynamic memory automatically, preventing memory leaks.
What are the different types of smart pointers?
The main types are std::unique_ptr, std::shared_ptr, and std::weak_ptr, each serving different ownership needs.
Can you give me an example of when to use std::shared_ptr?
Use std::shared_ptr when multiple owners need to share the same resource, like in a graph structure.
Are there any downsides to using smart pointers?
Yes, they can introduce overhead and complexity, especially with circular references in shared_ptr.
