  • 第4题：

    如果表达式++x/y中，++是作为友元函数重载的,/是作为成员函数重载的，则该表达式还可为

    A．(operator++(x)).operator/(y)

    B．(operator++(0)).operator/(y)

    C．operator/((operator++(x,0)),y)

    D．operator/((operator++(0)),y)


    正确答案：A
    解析：C++中用成员函数重载++x为：x.operator++()，用友元函数重载++x为：operator ++(x)，用成员函数重载x/y为：x.operator/(y)，用友元函数重载x/y为：operator/(x，y)。

  • 第5题：

    正确答案：编写Command1的Click事件代码如下： ThisForm. Release 编写Check1的InteractiveChange事件代码如下： IF This. Value＝1 ThisForm. Label1．Caption＝“身体健康!” ELSE ThisForm. Label1Caption＝“” ENDIF
    编写Command1的Click事件代码如下： ThisForm. Release 编写Check1的InteractiveChange事件代码如下： IF This. Value＝1 ThisForm. Label1．Caption＝“身体健康!” ELSE ThisForm. Label1，Caption＝“” ENDIF 解析：InteractiveChange是一个当用户使用键盘或鼠标更改控制的值时发生的事件。当复选框处于选中状态时，其Value值为1，否则为0。
