我有一个包含五个的程序。txt文件。这些文件被读入并放入不同的数组中。一个是一系列的名字。另外四个是带有测试分数的数组。

目前，该程序确实正确创建了阵列。接下来，程序将计算并显示每个测试的平均值（这很好）。然后程序会提示用户输入名称。如果找到一个名称，一个新的菜单将提示用户选择他们想要数据的测试。（这很好用）。

问题是：我在另一页上有主程序课和另一个成绩册课（做计算）。如何将这两页连接在一起？

例如：如果studentName是'Andrew'，并且在studentNameArray中找到了它，我选择了我想要查看的测试分数的1（scoreOneArray），说出数字88。我的程序找到了“Andrew”和“88”。它没有做的是将“Andrew”和“88”发送到成绩册，让数据计算测试百分比（88/100），并找到相应的字母成绩（在本例中为“B”）。最后，打印学生姓名、考试成绩（88%）和字母成绩。
