. getaverage在它的左边需要一个类

我一直得到一个错误，说" .getAverage需要一个类在它的左边"。

这是赋值提示符:

考试分数。编写一个名为TestScores的类。类构造函数应该接受一个考试分数数组作为参数。类应该有一个成员函数，返回考试成绩的平均值。如果数组中的任何测试分数为负或大于100，则该类应抛出异常。

异常应该有两个类;一个叫NegativeScore，另一个叫TooLargeScore。这些异常类将具有一个数据成员，该数据成员是一个称为score的整数值。该数据成员将通过参数在构造函数中设置。它还应该提供一个名为getScore的成员函数，该函数返回分数数据成员。

TestScores中称为getAverages的函数将计算数组中测试分数的平均值(作为双精度)。它还将检查分数是否为负或大于100。如果它是负的，它应该使用NegativeScore类抛出异常。如果分数大于100，则应该使用TooLargeScore类抛出异常。

Main将创建TestScores类的实例并捕获异常。因此，它需要处理两个异常，并显示带有无效分数的错误消息。
