How does C++11's try-catch affect performance?

C++11 introduced some optimizations for exception handling, but using try-catch can still impact performance.

What are the specific performance implications?

The overhead mainly comes from stack unwinding and the cost of throwing exceptions. It's generally more efficient to avoid exceptions in performance-critical code.

Are there best practices to minimize this overhead?

Yes, you can use exception specifications, avoid exceptions in tight loops, and prefer error codes for performance-sensitive sections.

Can you give an example of using error codes instead?

Sure! Instead of throwing an exception, you can return an error code from a function and handle it in the calling code.
