How do smart pointers affect performance in C++?

Smart pointers in C++ manage memory automatically, which can improve performance by reducing memory leaks.

Are there different types of smart pointers, and do they have different performance impacts?

Yes, there are three main types: unique_ptr, shared_ptr, and weak_ptr. Each has different overheads.

Which smart pointer is the most efficient in terms of performance?

unique_ptr is generally the most efficient as it has no reference counting overhead, unlike shared_ptr.

Can using smart pointers slow down my application?

If used improperly, especially shared_ptr, it can introduce overhead due to reference counting, potentially slowing down performance.

What are some best practices for using smart pointers in C++?

Use unique_ptr when ownership is clear, avoid shared_ptr unless necessary, and prefer make_shared for efficiency.
