How do smart pointers affect performance in C++?

Smart pointers in C++ manage memory automatically, which can improve safety but may introduce some overhead.

What types of smart pointers are there?

There are three main types: std::unique_ptr, std::shared_ptr, and std::weak_ptr. Each serves different purposes.

When should I use std::shared_ptr?

Use std::shared_ptr when you need shared ownership of an object, but be cautious of potential circular references.

Do smart pointers slow down my program significantly?

They can introduce some overhead, especially std::shared_ptr, but the benefits of safety often outweigh the costs.
