问:C++能不能在类中定义一个私有的静态常量数组?

fiowrf

如题,有点晦涩了,举个例子,想定义一个"学生"类如下:
//file ClassMate.h
string District[10]={"朝阳","海淀","宣武","东城","怀柔","密云"};//实际程序用拼音
class classmate{
private:
        string mName;
        int mHomeDistrictIndex;
public:
        classmate(){};
        .......;
};

我想,这里的string District[10]只供ClassMate类使用,不想让程序别的类也能看见并访问它,不知道该怎么解决?

大家别说我偏激啊,哈哈,我只是想,C++的一个思想是数据隔离,能隐藏的就隐藏.不知道这个该怎么隐藏呢?

我搞成了这个样子,mingw下报错:
class classmate{
private:
        static string District[10]={"朝阳","海淀","宣武","东城","怀柔","密云"};
        string mName;
        int mHomeDistrictIndex;
public:
        classmate(){};
        .......;
}

请大家指教!

static const string District[10]
这样试试。

class Operator:public BaseStructure{
private:
        OperatorType mType;
        static int ar[6];
        static const string OperatorSymbol[7]={"+","-","*","/","^","??"};
public:
..........
}
结果提示错误:
Operator.hxx:13: error: invalid in-class initialization of static data member
of non-integral type `const std::string[7]'

fiowrf

any idea?

在类外初始化
class Operator:public BaseStructure{
private:
        OperatorType mType;
        static int ar[6];
        static const string OperatorSymbol[7];
public:

}

const string Operator:OperatorSymbol[]={"+","-","*","/","^","??"};

静态数据在c++中只有 static const int t = 0;
可以初始化。
其他都要在类的外面。
