重载运算符“+”和“—”实现两复数的加、减运算。
void main( )
{
CComplex com1(3);
com1.show();
CComplex com2(5);
com2.show();
com2.assign(5,9);
com2.show();
(com1,com2).show(); //输出为8＋9i
(com1,com2).show(); //输出为-2-9i
}

自学了一天还是不会...疯求掉了...

求大神啊....

木有人吗...

明天就要交作业啦....跪求啊...

#include "iostream.h"
class CComplex
{
double real,imag;
friend CComplex add_complex(CComplex &,CComplex &);
public:
CComplex(double r,double i){real=r,imag=i;}
void assign(double r,double i){real=r;imag=i;}
void show()
{cout<<real<<"+"<<imag<<"i"<<endl;}
};
friend CComplex add_complex(CComplex &r,CComplex &i)
{
CComplex s;
s.show=r.assign+i.assign;
return s;
}
void main()
{
CComplex com1(3);
com1.show();
CComplex com2(5);
com2.show();
com2.assign(5,9);
com2.show();
(com1+com2).show();
(com1-com2).show();
}

研究半天还是不对啊...
