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

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

Using unique pointers helps manage memory automatically. Best practices include using them for resource management, avoiding raw pointers, and ensuring they are not copied.

Can you explain why I should prefer unique pointers over raw pointers?

Unique pointers provide automatic memory management, reducing the risk of memory leaks and dangling pointers, which are common with raw pointers.

Are there any situations where I shouldn't use unique pointers?

Yes, if you need shared ownership of an object, consider using shared pointers instead. Unique pointers are best for exclusive ownership.

How do I convert a raw pointer to a unique pointer?

You can convert a raw pointer to a unique pointer using std::make_unique or by directly initializing a unique pointer with the raw pointer.

What are some common mistakes to avoid when using unique pointers?

Common mistakes include trying to copy unique pointers, forgetting to release ownership, and using them inappropriately in data structures.
