What are the best practices for using raw pointers in C++?

When using raw pointers in C++, it's important to manage memory carefully. Always ensure that every new has a corresponding delete to avoid memory leaks.

Are there situations where using raw pointers is preferred over smart pointers?

Yes, raw pointers can be preferred in performance-critical sections where the overhead of smart pointers is not acceptable, or when interfacing with legacy code.

What are some common pitfalls to avoid with raw pointers?

Common pitfalls include dangling pointers, memory leaks, and double deletions. Always initialize pointers and set them to nullptr after deletion.

Can you explain the difference between a raw pointer and a smart pointer?

A raw pointer is a simple memory address, while a smart pointer (like std::unique_ptr or std::shared_ptr) manages memory automatically, helping to prevent leaks and dangling pointers.
