Ich habe vor, einen reinen Online-Fragebogen zu erstellen. Es gibt insgesamt zehn Fragen. Wenn Sie A wählen, erhalten Sie zwei Punkte, wenn Sie C wählen, erhalten Sie drei Punkte, und wenn Sie D wählen, erhalten Sie vier Punkte Die Ergebnisse werden direkt am Ende angezeigt. Derzeit besteht das Problem darin, dass der Benutzer, nachdem er in der ersten Frage A ausgewählt hat und später seine Antwort auf B ändert, seine Punktzahl nicht um einen Punkt verringert und dann addiert zwei Punkte. Mit welcher Methode lässt sich diese Frage lösen? Danke

第11道题,你怎么点,分数都不加也不减。
因为你没有对它进行计算,代码不用变化,把10改成11就可以了。
