编译通不过
#include <iostream>
using namespace std;
class base
{
    float real,image;
    public:
        base (){}
        base (float x,float y):real(x),image(y){
        }
         base operator + (base ,base );
        void show()
        {
            cout<<real<<" +"<<image<<"i"<<endl;
        }
};

 base base::operator+(base a,base b)
 {
     base c;
     c.real=a.real+b.real;
     c.image=a.image+b.image;
     return c;
 }
 
 main()
 {
     base a(1.2,4.5),b(2.2,5.5);
     base c;
     c=a+b;
     c.show();
 }
