1、【例4.8】定义复数Complex类，使用友元函数，完成复数的加法、减法、乘法运算，以及对复数的输出。#includeclassComplex{doublereal;doubleimage;public:Complex(doubler=0,doublei=0){real=r;image=i;}friendvoidinputcomplex(Complex&comp);friendComplexaddcomplex(Complexc1,Complexc2);friendComplexsubcomplex(Compl

2、exc1,Complexc2);friendComplexmulcomplex(Complexc1,Complexc2);friendvoidoutputcomplex(Complexcomp);};voidinputcomplex(Complex&comp){cin>>comp.real>>comp.image;}Complexaddcomplex(Complexc1,Complexc2){Complexc;c.real=c1.real+c2.real;c.image=c1.image+c2.image;returnc;}Compl

3、exsubcomplex(Complexc1,Complexc2){Complexc;c.real=c1.real-c2.real;c.image=c1.image-c2.image;returnc;}Complexmulcomplex(Complexc1,Complexc2){Complexc;c.real=c1.real*c2.real-c1.image*c2.image;c.image=c1.real*c2.image+c1.image*c2.real;returnc;}voidoutputcomplex(Complexcomp

4、){cout<<"("<

5、lt);cout<<"-------------------------"<

6、";outputcomplex(result);cout<

7、实现复数的四则运算，这是我们在第6章要讲到的运算符重载。
