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+20i2+3iresult: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();}
