2010-02-07T14:56:55 betterworldWo wuerdest Du den Code auf einer Skala von 1 bis 10 der Schwierigkeitsstufen fuer Aufgaben mit "pack" einordnen?
2010-02-07T14:47:54 biancaOha, du willst internes Debugging deiner Programme machen, kennst aber bestimmte Sachen nicht? Das wird schwierig.Wo finde ich denn da die Stelle, wie ich an den Variableninhalt komme?
Sorry, das übersteigt meine Fähigkeiten.
