第1题：
使用VC6打开考生文件夹下的工程test20_3，此工程包含一个源程序文件tes00_3.cpp，其中定义了用于表示复数的类comp，但类comp的定义并不完整。请按要求完成下列操作，将类comp的定义补充完整。
(1)定义comp的构造函数，函数含参数x和y，它们都是in，型的数据，默认值都为0，请使用参数列表的形式分别将类数据成员a和b初始化x和y的值。请在注释“//**1**”之后添加适当的语句。
(2)完成类comp的成员函数input(int x,int y)的定义，将int型的参数x和y分别赋值给数据成员s和b，请在注释“//**2**”之后添加适当的语句；
(3)完成类comp的友元函数friend compplus(comp &x,comp &y)的定义，该函数首先要定义一个comp类的对象c，然后将参数x和y的数据成员a与b分别相加并分别赋值给c的成员a和b，最后返回c的值，请在注释“//**3**”之后添加适当的语句。输出结果如下：
10+20i
2+3i
result：12+23i
注意：除在指定位置添加语句之外，请不要改动程序中的其他内容。
源程序文件test20_3.cpp清单如下：
include ＜iostream.h＞
class comp
{
int a;
int b;
public:
//**1**
friend comp plus(comp &x, comp &y);
void input(int x,int y)
{
//**2**
}
void output ( )
{
cout＜＜a＜＜'+'＜＜b＜＜"i"＜＜end1;
}
};
comp plus(comp &x, comp &y)
{
//**3**
c.b=x.b+y.b;
return c;
}
void main()
{
comp x(10,20),y,z;
y.input(2,3);
z=plus(x,y);
x.output();
y.output();
cout＜＜"result:";
z.output();
}

D. Configure the hard disks as one extended NTFS volume.
E. Place inventory_data.mdf on the first volume and inventory_log.ldf on the second volume.
F. Place inventory_data.mdf on the first volume and inventory_data2.ndf and inventory_log.ldf on the second volume.
G. Place inventory_data.mdf and inventory_log.ldf on the same volume.

第8题：
2 Which of the following are correct?
1. The balance sheet value of inventory should be as close as possible to net realisable value.
2. The valuation of finished goods inventory must include production overheads.
3. Production overheads included in valuing inventory should be calculated by reference to the company’s normal
level of production during the period.
4. In assessing net realisable value, inventory items must be considered separately, or in groups of similar items,
not by taking the inventory value as a whole.
A 1 and 2 only
