Books are to mankind what memory is to the individual. They contain the history of our race, the discoveries we have made, the accumulated knowledge and experience of ages．They picture for us the marvels and beauties of nature, help us out of difficulty, comfort us in sorrow, change hours of tiredness into moments of delight, fill our minds with good ideas and happy thoughts, and lift us out of and above ourselves. And also, books can help transport us to mountains or the seashore, and visit the most beautiful parts of the earth, without fatigue, inconvenience, or expense. In a sense they give us an even more vivid idea than the actual reality. So, precious and priceless are the blessings which the books scatter around our daily paths．We walk, in imagination, with noblest spirits, through the most fascinating regions.

  • 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。
