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, which is present in shared_ptr.

How does unique_ptr manage memory differently than raw pointers?

unique_ptr automatically deallocates memory when it goes out of scope, preventing memory leaks that can occur with raw pointers.

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

Yes, if you need shared ownership of an object, 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.
