What are the differences between raw pointers and smart pointers in C++?

What are the differences between raw pointers and smart pointers in C++?

Raw pointers are basic pointers that directly reference memory addresses, while smart pointers manage memory automatically, helping to prevent memory leaks.

Can you explain how smart pointers work in C++?

Smart pointers in C++ are objects that act like pointers but provide automatic memory management. They include unique_ptr, shared_ptr, and weak_ptr.

What are the advantages of using smart pointers over raw pointers?

The advantages include automatic memory management, prevention of memory leaks, and better exception safety.

Are there any downsides to using smart pointers?

Yes, smart pointers can introduce some overhead and complexity, especially in terms of performance and understanding ownership semantics.

When should I use raw pointers instead of smart pointers?

You might use raw pointers in performance-critical sections or when interfacing with legacy code that doesn't use smart pointers.
