#include <iostream>
using namespace std;
class A{
public:
    unsigned a;
    double b;
    unsigned c;
    double d;
};
void main(){
    A a;
    cout<<&a.a<<endl<<&a.b<<endl<<&a.c<<endl<<&a.d;
    cout<<endl<<"~~~~~~~~~~~~"<<endl;
    int e;
    double f;
    int g;
    unsigned h;
    cout<<&e<<endl<<&f<<endl<<&g<<endl<<&h;
}
为什么输出a,b,c,d的地址是由小到大，e,f,g,h的地址是由大到小
