一、程序清单

rvref.cpp  

// rvref.cpp -- simple uses of rvalue references
#include <iostream>inline double f(double tf) {return 5.0*(tf-32.0)/9.0;};
int main()
{using namespace std;double tc = 21.5;double && rd1 = 7.07;double && rd2 = 1.8 * tc + 32.0;double && rd3 = f(rd2);cout << \" tc value and address: \" << tc <<\", \" << &tc << endl;cout << \"rd1 value and address: \" << rd1 <<\", \" << &rd1 << endl;cout << \"rd2 value and address: \" << rd2 <<\", \" << &rd2 << endl;cout << \"rd3 value and address: \" << rd3 <<\", \" << &rd3 << endl;// cin.get();return 0;
}

执行结果：

tc value and address: 21.5, 00AFF768
rd1 value and address: 7.07, 00
