书本上的小程序，结构体也可以跟类一样包含函数吗？
#include<iostream>
using namespace std;
struct Complex{
private:
    double r;
    double i;
public:
    void init(double rr,double ii){r=rr;i=ii;}
    double real(){return r;}
    double image(){return i;}
};
void main()
{
    Complex a;
    a.init(2,3);
    cout<<a.real()<<"+"<<a.image()<<"i"<<endl;
}
