/*定义复数类Complex，
（1）定义私有数据成员，实部和虚部；
（2）定义带默认值的构造函数，给数据成员赋值，默认值为0；
（3）定义输出函数void display()，输出格式如“3+4i”或“-3-4i”；
（4）定义复数与复数的加、减运算符重载；复数加实数运算符重载；赋值运算符重载；
（5）定义主函数，对上述成员函数进行测试。
b=4+5i
c=a=2+3i
f=a+b=6+8i
d=a+4=6+3i
g=a-b=2+2i

Complex operator =(Complex & c)

return *this;
}
Complex operator -(Complex &百度文库c)
b.display();
c=a;
cout<<"c=a=";
c.display ();
f=a+b;
cout<<"f=a+b=";
f.display();
d=a+4;
cout<<"d=a+4=";
d.display ();
g=a-b;
cout<<"g=a-b=";
g.display();
}
结果：
a=2+3i

temp.real =c.real -real;
temp.imag =c.imag -imag;

{
Complex a(2,3),b(4,5),c,d,f,g;
cout<<"a=";
a.display();
cout<<"b=";
