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, always prefer it over raw pointers for resource management. Make sure to use std::make_unique for allocation.

Can you explain why std::make_unique is preferred?

std::make_unique prevents memory leaks and is exception-safe, ensuring that memory is properly managed even if an exception occurs.

Are there any situations where I shouldn't use std::unique_ptr?

Yes, avoid using std::unique_ptr for non-heap objects or when you need shared ownership; in those cases, consider std::shared_ptr.

What about using std::unique_ptr with arrays?

For arrays, use std::unique_ptr<T[]> to manage dynamic arrays, ensuring proper deletion of the entire array.
