  • 第3题:

    有以下程序: class Date { public: Date(int y,int m,int D) ; { year =y; month=m; day=d; } Date(int y=2000) { year=y; month=10; day=1; } Date(Date &D) { year=d.year; month=d.month; day=d.day; } void print () { cout<<year<<"."<<month<<"."<<day<<end1; } private: int year,month,day; }; Date fun(Date D) { Date temp; temp=d; return temp; } int main() { Date date1(2000,1,1),date2(0,0,0); Date date3(date1); date2=fun(date3); return 0; } 程序执行时,Date类的拷贝构造函数被调用的次数是

    A.2

    B.3

    C.4

    D.5


    正确答案:B
    解析:本题考核拷贝构造函数。上述程序中,拷贝构造函数一共被调用了3次:第一次是在执行语句Datedate3(date1);时,用已经建立的对象date1对正在建立的对象date3进行初始化:第二次是在调用fun函数时,由于是传值调用,因此实参对象date3要对形参对象d进行初始化;第三次是在执行fun函数中的返回语句returntemp;时,系统用返回初始化一个匿名对象时使用了拷贝构造函数。

  • 第4题:

    查询最近30天的记录应使用( )作为准则。

    A.Between Date()And Date()一30

    B.Between Date()一30 And Date()

    C.<;=Date()一30

    D.<;Date()一30


    正确答案:B
    B.【解析】本题考查查询准则的知识。获得当前日期可以使用系统函数Date(),而当前日期的30天前就是日期Date()一30。最近30天内的记录,也就是日期在这个区间内的记录,使用关键字Between…And…来表示在区间内,注意先写下限后写上限。

  • 第5题:

    在某数据表中的执勤时间字段查找执勤时间30 之内的准则是( )。

    A.Between Date()Or Date-30

    B.Between Date()And Date()-30

    C.<Date()And>Date()-30

    D.<Date()Or>Date()-30


    正确答案:B
    解析:Date(date)返回给定日期1~31的值,表示给定日期是一个月中的哪一天;Date()返回系统当前日期;Between用于指定一个字段值的范围,指定的范围之间用And连接。选项A和D使用or连接是错误的,选项C的用法是错误的,答案为B。

    C.Test Date=date("1/1/2002")

    D.Test Date=Format("m/d/yy","1/1/2002")


    正确答案:A
    解析:本题考查日期型数据的用法,题目难度较小。解答本题首先应该注意日期型数据单独存在时前后需要用#号,选项B书写错误: Date函数不能带参数,选项C错误;Format函数可以将字符串数据转换为日期形式,但是该函数的格式是:Format(expressionLformat]- Lfirstofweek[,firstweekofye盯)D,即选项D中两个参数的顺序出现错误。答案为A。

    B)Between Date( )-30 And Date( )

    C)<=Date( )-30

    D)<Date( )-30


    正确答案:B
    本题考查查询准则的知识。获得当前日期可以使用系统函数Date0,而当前日期的30天前就是日期Date0.30。最近30天内的记录,也就是日期在这个区间内的记录,使用关键字Between…And…来表示在区间内,注意先写F限后写上限。
