Well, you can either actually construct the "Invalid index: X" and put it in the exception -OR- you can create an exception class that takes a string AND an int then make the "what" function format them. We chose the kind of the latter at a company where I worked.... we added an exception class that held both a string and an int.... and, of course, added an accessor for the int (kinda like what() is an accessor for the string)..... so if you needed to output both the string and the int you could cout << e.what() << ' ' << e.code(); [deleted] Victor A.
