Kuinka hypätä silmukan ulkopuolelle? alla olevassa ohjelmassa miten käytetään gotoa tai muuta hyppyyn liittyvää ohjelmaa

• Muotoile koodi oikein. En voi ' t seurata mitä siellä tapahtuu.
• Kyllä, ikävä pala spagettikoodia (todella hienosti sanottu).
• Ja C ++ -muotoilijan käytön jälkeen ' on melko selvää, miksi se voi ' ei toimi
• Vain curiositeetin x1, x2, x3, fault = 0; on tarkoitus asettaa muuttujat nollaksi? Minulla on huonoja uutisia sinulle.
