数以百计的；没有名为“的成员”；错误C++； 我刚开始C++编程，所以请原谅我这是一个可怕的错误，但它正在我的脑袋里。< /P>

我有多个正确编程的.cpp文件，编译后没有错误，都有自己的.h文件

出于某种原因，当我试图编译一个名为“flyingUnit.cpp”的类时，我会遇到数百个错误，都是这样的：

flyingUnit.cpp: In constructor ‘FlyingUnit::FlyingUnit(const char*, const char*, double, double,
bool, const char*, const char*, int, const char*)’:
flyingUnit.cpp:26:38: error: class ‘FlyingUnit’ does not have any field named ‘length’
             const char* weyr ) : length(length), wingspan(wingspan), age(age)
                                  ^

我完全不知道为什么会发生这种情况，课堂上使用的所有东西都找不到，完全目瞪口呆，而其他所有的课程似乎都很好。为什么我会犯这些错误

ostream&operator您的类FlyingUnit中缺少一个成员变量“double length”


请注意，在您的合同中

FlyingUnit::FlyingUnit( const char* dragonName, const char* dragonColour,
        double length, double wingspan, bool breatheFire,
        const char* riderName, const char* rank, int age,
        const char* weyr ) : length(length), wingspan(wingspan), age(age)



您尝试初始化不存在的变量；长度、翼展和年龄。。。尝试在标题中声明这些内容
 你读到错误了吗
class'FlyingUnit'没有任何名为'length'的字段。
对我来说非常清楚。我无法提供完整的错误，大约400行长，并表示“class FlyingUnit'没有名为'xxxxx'的成员”everything@Burgtaro如果您已经开发了此代码，请更频繁地编译，或者使用带有intellisense的IDE。所有这些都是
FlyingUnit
s成员，而不是
FlyingUnit
的成员。我修复了它，感谢您的帮助！我提供的错误就是一个例子，它发生在构造函数中的每个变量上，查看您在类中定义的数据成员。您试图访问的变量并不存在。@Burgtaro他给出的答案只是一个例子：P，而且大多数其他成员都只是丢失了是的，所有长度、翼展、年龄都丢失了。我对其他4个类和.h文件做了完全相同的操作，效果非常好，出于某种原因，这一个无法识别任何内容
