我一直遇到一个错误，指出cootie.h中声明的变量和函数无法在main.cpp文件中访问。基本上它说它们不在其范围内。任何帮助都会很棒，我无法弄清楚这一点。

编辑：不再得到函数和变量的错误不在main.cpp范围内，但现在它说的是“cootie c;”有一个不完整的类型。

修正了它，我忘记了我的打印功能的参数，现在一切正常，感谢您的帮助！

Answer 1

你有类似这个的电话：

setName(name);

未定义的非成员函数setName。您可能要调用的函数是类cootie的成员函数。应该在该类的对象上调用它，如下所示：

cootie c;
c.setName(...);

Answer 2

在你的main.cpp中尝试访问它们：

cootie::<variable or function>

我也意识到那些不是静态函数，你需要添加一个cootie对象：

cootie myNewCootie;
myNewCootie.<functions and whatnot>

Main.cpp无法访问头文件和其他.cpp文件中的变量和函数
