如何快速输出C++结构体的成员名和其值

#include <iostream>
#include <string>
#define Name(X) #X
#define Out(X) {string xname=Name(X);cout<<xname.substr(2,xname.size()-1)<<": "<<X<<endl;}
using namespace std;

struct A
{
int x;
int y;
};

struct B
{
float w;
int u;
double v;
A a;
};

void outA(A v)
{
Out(v.x);
Out(v.y);
}

void outB(B v)
{
Out(v.a.x);
Out(v.a.y);
Out(v.u);
Out(v.v);
Out(v.w);
}

int main()
{
A a={1,2};
B b={1.1,10,2.34,a};
outA(a);
outB(b);
return 0;
}
