Questions tagged [exception]
An exception is an unusual condition that requires deviation from the program's normal flow. Normally, an exception should not result in total failure, but instead be attended by an exception handler. Exception handling is a built-in construct in many programming languages. Usually, exceptions are handled by unwinding the stack, thus rolling back to a defined state outside the exception's scope, and then invoking a handler block or routine.
