How do exceptions affect performance in C++?

How do exceptions affect performance in C++?

Exceptions in C++ can introduce overhead due to stack unwinding and the need for additional code to handle them.

Is the performance impact significant in high-frequency code paths?

Yes, in high-frequency code paths, the overhead can be noticeable, so it's often better to use error codes.

Are there any best practices to minimize the performance impact?

Yes, you can minimize impact by using exceptions for truly exceptional cases and avoiding them in performance-critical sections.

What about using noexcept? Does it help?

Using noexcept can improve performance by allowing the compiler to optimize code better, as it knows exceptions won't be thrown.
