What is the performance impact of using smart pointers in C++?

Smart pointers in C++ can improve memory management but may introduce overhead. Would you like to know more about specific types?

Yes, can you explain the differences between std::unique_ptr and std::shared_ptr?

Certainly! std::unique_ptr is lightweight and has no overhead, while std::shared_ptr uses reference counting, which adds some overhead.

Does using std::shared_ptr significantly affect performance?

It can, especially in performance-critical applications. The overhead comes from managing the reference count, which can slow down operations.

Are there scenarios where using raw pointers is better?

Yes, in cases where performance is critical and you can ensure proper memory management, raw pointers may be preferable.
