What are some use cases for raw pointers in C++?

Raw pointers in C++ are often used for dynamic memory management, interfacing with low-level APIs, and implementing data structures like linked lists.

Can you explain how raw pointers differ from smart pointers?

Sure! Raw pointers do not manage memory automatically, while smart pointers like std::unique_ptr and std::shared_ptr handle memory management and help prevent leaks.

When should I prefer using raw pointers over smart pointers?

You might prefer raw pointers in performance-critical sections where you need fine control over memory, or when interfacing with legacy code that requires them.

Are there any risks associated with using raw pointers?

Yes, raw pointers can lead to memory leaks, dangling pointers, and undefined behavior if not managed carefully. It's crucial to ensure proper memory allocation and deallocation.

What are some best practices for using raw pointers?

Best practices include ensuring proper ownership, avoiding memory leaks by matching new with delete, and using nullptr instead of NULL for better type safety.
