C++ Error Codes Best Practices

What are some best practices for handling error codes in C++?

Some best practices include using exceptions for error handling, defining clear error codes, and documenting them.

Can you explain why using exceptions is preferred over error codes?

Using exceptions allows for cleaner code and separates error handling from regular logic, making it easier to maintain.

What should I do if I encounter an error code I don't understand?

You should consult the documentation for the library or framework you're using, as it often provides explanations for error codes.

Are there any common error codes I should be aware of?

Yes, common error codes include EIO for input/output errors and ENOMEM for memory allocation failures.
