If you always handle exceptions immediately in the caller of a method that can throw an exception, then exceptions become useless, and you’d better use error codes.

Does throwing exception break?

Does catch stop the program?

Program execution doesn’t resume until a catch-block somewhere in the call stack catches the exception. All methods in the call stack between the method throwing the exception and the method catching it have their execution stopped at the point in the code where the exception is thrown or propagated.
