Years ago, when Dad moved to the US, I had to go to school in New York. I was worried. How could I, an 8-year-old girl from , make friends in America? On my first day at Anna Silver School, I met Miss Alice Green, my class . She spoke to me slowly and to get me used to her American accent. When she discovered that I drawing, she took me as the teacher. Miss Green made sure that I fit into (适应) her class easily, and before I knew it, I was already having fun, just as other schoolgirls were. When Dad was sent back to India, I had to Anna Silver School. I was again. Miss Green had planned to take us students for a trip, but I had to say goodbye to them now. So, with a heart, I left my school and the US. Back in India, I received a package one day. It was Miss Green and my classmates. They had written me a letter each, me about the fishing trip. Miss Green said she me very much. With her good wishes, she added: “Keep up with your drawing, you love it so much.” I’m very to Miss Green. She not only made a shy little feel at home in a faraway country, but also taught me and my classmates to understand the importance of being kind to others at an early age.

使用VC6打开考生文件夹下的源程序文件3.cpp,其中定义了类A、A1和A2,其中A1类由A类公有派生,A2类由A1类公有派生。
(1)定义类A的构造函数,该构造函数有一个整型的参数x,在构造函数中请将X赋值给数据成员a。请在注释“//********1********”之后添加适当的语句。
(2)定义类A1的构造函数,该构造函数有两个整型的参数x和y,在构造函数中请将X赋值给数据成员b,将y作为基类A构造函数的参数值传入。请在注释“//********2********”之后添加适当的语句。
(3)定义类A2的构造函数,该构造函数有3个整型的参数x,y和z,在构造函数中请将X赋值给数据成员c,将y和z分别赋值给基类A1构造函数的参数x和y。请在注释“//********3********”之后添加适当的语句。
(4)完成类A2的成员函数show的定义,该函数调用基类成员函数,输出基类书局成员a和b及类A2自身的数据成员c的值,上述3个值在输出时以空格隔开。请在注释“//********4********”之后添加适当的语句。
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。
程序输出结果如下:

7 3 8
注意:除在指定的位置添加语句之外,请不要改动程序的其他部分。
试题程序:
#include<iostream.h>
class A
int a;
public:
//********1********
int geta()return a;
;
class A1:public A
int b;
public:
//********2********
int getb()return b;
;
class A2:public A1
int c;
public:
//********3********
void show()
//********4********
;
void main()
A2 a(8,3,7);
cout<<a.geta()<<end1;
cout<<a.getb()<<end1;
a.show();
