// but the "real" solution is much more complicated

从jpgraph

Exception up = new Exception("Something is really wrong.");
throw up;  //ha ha

I was doing a database in Access, very simple thing - at least it was supposed to be at the start or I would have done it in Delphi. The client wanted to be able to get the customer info out of the database but they would not enter enough information to reliably identify the customer. I told them to use the phone number as the key as each customer (the way they worked, not for everyone) would have a different number. After a few frantic calls from them, (It's not working we can't enter the customer) I discovered that they were too lazy to look up the phone numbers from their old system and were trying to enter all the numbers they did not know as "n/a". In trying to sort this out for them I ended up with a lot of checking loops in the code and had the comment beside one outcome "This should never be reached if they do what they are supposed to do!!!!!!!!!"

他们还曾经问过我:“即使我们输入了错误的地址，我们如何才能找到正确的客户?”而这一切都是为了花生。

// Sorry dirty code

int main(void)

在eMule, Preferences.cpp中，强制最小上传速度限制与下载速度限制成正比的方法:

uint16 CPreferences::GetMaxDownload(){
//dont be a Lam3r :)
    uint16 maxup=(GetMaxUpload()==UNLIMITED)?GetMaxGraphUploadRate():GetMaxUpload();
    if( maxup < 4 )
        return (( (maxup < 10) && (maxup*3 < prefs->maxdownload) )? maxup*3 : prefs->maxdownload);
    return (( (maxup < 10) && (maxup*4 < prefs->maxdownload) )? maxup*4 : prefs->maxdownload);
}
