What are the performance benefits of using unique_ptr in C++?

What are the performance benefits of using unique_ptr in C++?

Using unique_ptr can improve performance by eliminating the overhead of reference counting, as it has sole ownership of the object.

How does unique_ptr compare to raw pointers in terms of memory management?

Unlike raw pointers, unique_ptr automatically manages memory, ensuring that the memory is freed when the unique_ptr goes out of scope.

Are there any scenarios where using unique_ptr might not be the best choice?

Yes, if you need shared ownership of an object, std::shared_ptr would be more appropriate than unique_ptr.

Can unique_ptr be used with arrays?

Yes, you can use unique_ptr with arrays by using std::unique_ptr<Type[]> to manage dynamic arrays.
