在代码的近端，我希望它根据某人的分数显示他们做得有多好。如果你得了5分，它应该显示"完美"，如果你得了4分，它应该显示"很好"，如果你得了3分，它应该显示"很好"，如果你得了2分，它应该显示"不错的尝试"，如果你得了1分，它应该显示"下次更好地尝试"，如果你得了0分，它应该显示"你失败了"。另外，每次你得到一个正确的答案，它将被添加到"正确的数字的数量"和"错误的答案的数量"，如果错误的。
所以我尝试了所有的方法来使它工作到目前为止我所知道的关于编码的知识，但仍然不起作用。我尝试改变关系运算符和添加逻辑运算符，但仍然不起作用。如果它得到5分，它不会显示任何东西，那么如果它得到4分，它将显示"完美"。如果它得到3分，它将显示"很好"。如果它得到2分，它将显示"好"。如果它得到1分，它将显示"不错的尝试"。最后，当它得到0分时，它将显示"下次更好地尝试"。

这是因为：
在代码末尾的这些行中，您只需为每个行添加一个，而不是打印它们，但当您得到5个正确答案时，
correctAnswer变量已经是5，因此您也不需要添加1。
