【问题描述】：
在代码的近端，我希望它根据分数显示某人的表现。如果你得到 5 分，它应该显示“Perfect”，如果你得到 4 分，它应该显示“Great”，如果你得到 3 分，它应该显示“Good”，如果是 2 分，它应该显示“Nice Try”，如果是 1 分，“Try better next time”，如果是 0 分，则显示“You Failed” . 此外，每次您得到正确答案时，都会将其添加到“正确数字的数量”中，如果错误则添加到“错误答案的数量”中。
因此，我尝试了所有方法以使其适用于我目前所知道的有关编码的知识，但仍然无法使用。我尝试更改关系运算符并添加逻辑运算符，但仍然无法正常工作。如果得分为 5，则不会显示任何内容，如果得分为 4，则显示“Perfect”。如果它得到 3 分，它将显示“Great”。如果它得到 2，它将显示“Good”。如果它得到 1，它会显示“Nice Try”。最后，当 0 时，它显示“下次尝试更好”。

删除
printf("\nNumber of Correct Answers: %d\n", correctAnswer++);和printf("Number of Wrong Answers: %d\n", wrongAnswer++);中的++。
