How does std::unique_ptr perform compared to raw pointers in C++?

How does std::unique_ptr perform compared to raw pointers in C++?

std::unique_ptr generally offers better performance than raw pointers due to its automatic memory management and reduced overhead.

What are the main advantages of using std::unique_ptr?

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

Are there any performance drawbacks to using std::unique_ptr?

In some cases, std::unique_ptr may introduce slight overhead due to its additional features, but this is often negligible.

Can std::unique_ptr be used with arrays?

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

How does std::unique_ptr compare to std::shared_ptr?

std::unique_ptr is for single ownership, while std::shared_ptr allows multiple pointers to share ownership of the same resource.
