What are the differences between C++ exceptions and error codes?

What are the differences between C++ exceptions and error codes?

C++ exceptions are used for error handling by throwing and catching errors, while error codes are returned by functions to indicate success or failure.

When should I use exceptions instead of error codes?

Use exceptions when you want to separate error handling from regular code flow, especially for unexpected errors.

Are there performance implications when using exceptions?

Yes, exceptions can introduce overhead, especially if they are thrown frequently. Error codes can be more efficient in performance-critical applications.

Can I mix both approaches in my C++ code?

Yes, you can mix both. Use exceptions for critical errors and error codes for expected conditions, but be consistent in your approach.
