suppose I have a statement like:
throw;
(throw without a type exception)
Can I know what is the default exception for c++?
It seems to me: if there is no outer layer exception, statement
throw ;
will return a notype exception and cause Abort anyway even if
I use
catch (...)
Any idea, thanks,

throw without an operand means re-throw. if re-throw is used in a context
when
there is no exception, terminate () will be called.

Thanks for confirmation, this is exactly what I guess :)
