What are the best practices for using raw pointers in C++11?

In C++11, it's recommended to minimize the use of raw pointers. Instead, consider using smart pointers like std::unique_ptr and std::shared_ptr for better memory management.

Can you explain why smart pointers are preferred over raw pointers?

Smart pointers automatically manage memory, reducing the risk of memory leaks and dangling pointers. They also provide better ownership semantics.

Are there any specific scenarios where raw pointers are still useful?

Yes, raw pointers can be useful for performance-critical code or when interfacing with legacy APIs. However, use them cautiously.

What about using nullptr instead of NULL?

Using nullptr is preferred in C++11 as it provides a type-safe null pointer constant, improving code clarity and safety.
