Error Codes and std::error_code
Error codes provide an alternative to exceptions for error handling. They're explicit, predictable, and have zero overhead in the success case, making them ideal for performance-critical code and systems programming.

Exceptions provide a mechanism to transfer control from a point where an error occurs to a handler that can deal with it. They separate error-handling code from normal logic, making code cleaner and more maintainable.
