  • 第1题:

    阅读下列函数说明和Java代码,将应填入(n)处的字句写在对应栏内。

    【说明】

    通常情况下,用户可以对应用系统进行配置,并将配置信息保存在配置文件中,应用系统在启动时首先将配置文件加载到内存中,这些内存配置信息应该有且仅有一份。

    下面的代码应用了单身模式(Singleton)以保证Configure类只能有一个实例。这样,Configure类的使用者无法定义该类的多个实例,否则会产生编译错误。

    include <iostream.h>

    class Configure{

    (1);

    Configure(){}; //构造函数

    public:

    static Configure *Instance();

    public:

    int GetConfigureData(){return data;} //获取配置信息

    int SetConfigureDate(int m_data)

    {data=m_data; return data;} //设置配置信息

    private:

    static Configure* _instance;

    int data; //配置信息

    };

    (2)=NULL;

    Configure * Configure∷Instance()

    { if(_instance==NULL)

    { _instance=(3);

    //加载配置文件并设置内存配置信息,此处省略

    }

    return (4);

    }

    void main()

    { Configure *t=NULL;

    t=(5);

    int d=t->GetConfigureData();

    //获取配置信息后进行其它工作,此处省略

    }


    正确答案:(1)public (2)Configure *Configure∷_instance (3)new Configure (4)_instance (5)Configure∷Instance()
    (1)public (2)Configure *Configure∷_instance (3)new Configure (4)_instance (5)Configure∷Instance() 解析:(1)public
    C++类中,构造函数属于公有成员函数,因此应该填入:public。
    (2)Configure *Configure∷_instance
    C++类中静态成员变量赋初值,只能在函数和类外进行。
    (3)new Configure
    Instance是类Configure的静态成员函数,它只能访问类的静态成员_instance,当指针_instance为NULL时,应该给_instance动态分配内存,所以此处应该填入:new Configure。
    (4)_instance
    类Configure的静态成员函数Instance的返回值是Configure*,即Configure类指针类型,由于此函数只能访问类的静态成员_instance,因此返回值应当是指针_instance。所以此处应该填入:_instance。
    (5)Configure∷Instance()
    t是一个Configure类指针,初值为NULL,因此此处必须首先动态开辟一个Configure类对象,让t指向这个对象,下面才能进行d=t->GetConfigureData()访问对象的成员函数。所以此处应该填入:new Configure。
