我正在尝试制作学生成绩单（约10名学生）
我收到1个错误，即＆＃34; ERROR TESTING.CPP 18 :)预期＆＃34;请查看代码并帮助我。
当我删除参数时，我得到25个错误。
我还没有被教过关于班级或工会的事。
我只知道结构。因此，请不要在结构之外提供解决方案。

void grade(student U[].marks) // THIS BLOCK IS GIVING ERROR
这不是一个块，它是一个函数声明，它给出了一个错误，因为它不是有效的C ++。你需要声明一个参数及其类型，这不是你怎么做的。你做的方式完全取决于你打算参数的类型，甚至不是很清楚。

好的我修正了错误
空缺等级（学生U []。标记）替换为空缺等级（浮动G）
