What are the differences between smart pointers and raw pointers?

What are the differences between smart pointers and raw pointers?

Smart pointers are objects that manage memory automatically, while raw pointers are simple memory addresses without management.

Can you give me examples of smart pointers?

Sure! Common examples of smart pointers in C++ include std::unique_ptr, std::shared_ptr, and std::weak_ptr.

What are the advantages of using smart pointers?

Smart pointers help prevent memory leaks and dangling pointers by automatically managing the memory they own.

Are there any downsides to using smart pointers?

Yes, smart pointers can introduce some overhead and complexity, especially in terms of performance and circular references.

When should I use raw pointers instead of smart pointers?

Use raw pointers when you need low-level memory management or when interfacing with legacy code that doesn't use smart pointers.
