8.2 引用变量  page225

注：必须在声明时进行初始化

#include <iostream>

int main()
{
        using namespace std;

        int rats = 10;
        int &rorats = rats;

        cout <<"rats= "<< rats;
        cout <<",rodents= "<<rorats<<endl;

        rorats++;

        cout <<"rats= "<< rats;
        cout <<",rorats = "<< rorats <<endl;

        cout <<"rats address=" << &rats;
        cout <<",rorats address ="<< &rorats <<endl;

        return 0;
}

ywx@yuweixian:~/yu/c++$ ./firstref
rats= 10,rodents= 10
rats= 11,rorats = 11
rats address=0xbfb3ffbc,rorats address =0xbfb3ffbc
