2.32.2.Use References operator &

#include <iostream>



int main()

{

    int  intValue;

    int &intReference = intValue;



    intValue = 5;

    std::cout << "intValue: " << intValue << std::endl;

    std::cout << "intReference: " << intReference << std::endl;



    std::cout << "&intValue: "  << &intValue << std::endl;

    std::cout << "&intReference: " << &intReference << std::endl;



    return 0;

}

intValue: 5
intReference: 5
&intValue: 0x22ff74
&intReference: 0x22ff74
