a slight optimization improvement in this answer's 3rd code snippet. By moving the if(n < 0) check in the very start of the function, two integer declarations can be saved.

| Mar 29, 2016 at 23:26 | comment | added | whatsisname | @Luaan: that's not the responsibility of the example function, though. | |
| Mar 29, 2016 at 8:52 | comment | added | Luaan | "Fail fast to the nearest safe state" is more reasonable. If you make your application so that it crashes when something unexpected happens, you risk losing the user's data. Places where the user's data is in jeopardy are great points for "penultimate" exception handling (there's always cases where you can do nothing but throw your hands up - the ultimate crash). Only making it crash in debug is just opening another can of worms - you need to test what you're deploying to the user anyway, and now you're spending half of your testing time on a version the user is never going to see. | |

Taking JDługosz's advice to use an ArgumentException
|
| Mar 28, 2016 at 10:30 | comment | added | Kevin | @JDługosz Yep! C# has an ArgumentException, and Java has an IllegalArgumentException. | |
| Mar 28, 2016 at 8:06 | comment | added | JDługosz | Doesn't c# have a particular kind of exception to indicate invalid arguments or out-of-range arguments? | |
