error handling

error handling
   The way that a program copes with errors or exceptions that occur as the program is running.
   Good error handling manages unexpected events or wrongly entered data gracefully, usually by opening a dialog box to prompt the user to take the appropriate action or to enter the correct information. Badly written programs may simply stop running when the wrong data is entered or when an unanticipated disk error occurs.
