PDAs, Cellphones, Wireless There's an article making the rounds right now about how applications on iOS crash more often than applications on Android. I'm not going to detail the entire methodology - the article itself does so - but it does raise an interesting talking point about how both mobile operating systems handle application crashes and updates.

Handling a division-by-zero error in C++ is trivial. Subclass std::runtime_error and handle it like you would any other exception.

Only if you're using visual C++ and their silly structured exception handling, which is pretty bad for various reasons, including performances. Throwing an exception on a division by zero is non standard behavior.

Also, a division by 0 won't necessarily cause the program to halt. If you work with floats it will usually just yield a special type of NaN value indicating an infinite.

The best way to deal with divisions by 0 is to special case the situations where they can happen, or assert if it is never supposed to happen.
If you don't explicitly deal with the division by 0 cases it can result in either a crash (that includes uncaught exceptions) or bugged behavior, in absolutely any language.
