How can I handle errors in C++ without affecting performance?

How can I handle errors in C++ without affecting performance?

You can use exception handling judiciously, but for performance-critical code, consider using error codes instead.

What are the trade-offs between using exceptions and error codes?

Exceptions provide cleaner code and automatic stack unwinding, but they can introduce overhead. Error codes are faster but can lead to more complex code.

Are there specific scenarios where one is preferred over the other?

Yes, use exceptions for high-level error handling and error codes for low-level, performance-sensitive sections.

Can you give an example of using error codes in a function?

Sure! Here's a simple function that returns an error code instead of throwing an exception when it fails.
