How do C++ exceptions affect performance?

How do C++ exceptions affect performance?

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

Is the performance impact significant in real-time applications?

In real-time applications, the performance impact can be significant, especially if exceptions are thrown frequently.

Are there alternatives to using exceptions in C++?

Yes, alternatives include using error codes, assertions, or even custom error handling mechanisms.

What are the best practices for using exceptions in C++?

Best practices include using exceptions for exceptional cases only, avoiding exceptions in performance-critical code, and ensuring proper resource management.
