C++ 获取）函数参数中的预期错误

我正在试着做一张学生成绩单（大约10名学生）

我得到1个错误，即“error TESTING.CPP 18:）EXPECTED”，请查看代码并帮助我

当我删除这个参数时，我得到了25个错误

我还没学过关于班级或工会的知识

我只知道。所以请不要给出结构之外的解决方案

这不是块，它是函数声明，它给出错误，因为它不是有效的C++。需要声明一个参数及其类型，而这不是你如何做的。你怎么做完全取决于你想要的参数是什么类型，甚至不太清楚。< /P> < P> OK，我修正了错误
void grade（学生U[]分数）被void grade（float G）
手工制作a可以让你自己很快发现这个问题。无关：TurboC++已经过时了大约30年。我强烈建议更新你的编译器和学习材料。你为什么要传入
U[]“标记< /代码>，而不是只是代码> U/COD>？为什么你要指定函数参数为<代码>学生U[]？McAs/Cuth>？这是不正确的。<代码>包含< < /代码>——你是另一个不得不使用恐龙Turbo C++编译器的穷学生吗？你的代码与任何现代C++编译器都是不可编译的。我如何传递这个论点，例如：.marks.phy（从void marks（）到grade（）函数？
