What are the best practices for using std::unique_ptr in C++?

What are the best practices for using std::unique_ptr in C++?

When using std::unique_ptr, it's best to ensure that you use it for sole ownership of dynamically allocated objects. Avoid using raw pointers.

Can you explain how std::unique_ptr handles memory management?

std::unique_ptr automatically deallocates the memory it owns when it goes out of scope, preventing memory leaks.

Are there any specific scenarios where std::unique_ptr is not recommended?

Yes, avoid using std::unique_ptr in situations where shared ownership is required; in such cases, std::shared_ptr is more appropriate.

What are the advantages of using std::unique_ptr over raw pointers?

The main advantages include automatic memory management, prevention of memory leaks, and clearer ownership semantics.
