  • 第1题：

    类 Contain 的定义如下： class Contain { private: int x; protected: int z; public: class Embed { private: int y; public: Embed ( ) { y=100; } int Embed_Fun(); }MyEmbed; int Contain_Fun(); }； 下列对上面定义的描述中，正确的是( )。

    A．定义类Embed对象的语句是：Contain：：Embed Myobject；

    B．类Contain的成员函数Contain_Fun()中可以访问对象MyEmbed的私有成员y

    C．类Embed的成员函数Embed_Fun()中可以直接访问类Contain的所有成员

    D．类Embed的成员函数Embed_Fun()中只能直接访问类Contain的公有成员


    正确答案：A
    解析：对象MyEmbed是类Contain的成员对象，通过对象MyEmbed不能访问其私有数据成员y，所以选项B是错误的。类Embed是类Contain的嵌套类，类Embed的成员函数不能直接访问类Contain的所有成员，所以选项C和D都是错误的。
