So wurde ich beauftragt, ein grundlegendes Hotelverwaltungssystem zu verursachen. Während ich insgesamt zufrieden mit meiner Arbeit bin, habe ich festgestellt, dass, nachdem ich mehr als 2 Daten bei der Funktion user() eingegeben habe, die Option break after start() die update() Funktion aufrufen würde, während sie das Programm beenden sollte. Ich habe den ganzen Code eingeschlossen, da ich keine genaue Idee habe, wo das Problem liegt. Bitte helfenZeigt Funktion nach Pause an

Die einzigen verwandte Funktionen meiner Meinung nach den Benutzer ist() und update(), denn wenn ich das Update() Funktion zu entfernen, es keine andere Funktion aufrufen, nicht gehen.
Bitte Code richtig einrücken. Es ist wirklich schwer es so zu machen wie es ist – Mureinik
Bitte erstellen Sie ein [mcve] oder debuggen Sie einfach Ihr Programm –
Können Sie diesen Code vereinfachen, so dass er sich auf das Problem konzentriert? Entfernen Sie den gesamten Code, der nicht als Teil des Szenarios ausgeführt wird. Was haben Sie beim Debuggen des Programms festgestellt? –
