C/C++ 指针 <一>

//address.cpp
//using the & operator to find addresses
#include <iostream>
int main()
{
    using namespace std;
    int donuts = 6; //donuts dron^ts n, 甜甜圈
    double cups = 4.5;
   
    cout << "donuts value = "<< donuts << "\t";
        //donuts 代表变量值， &donuts代表变量地址
    cout << " and donuts address = "<< &donuts<<endl;
    // NOTE : you may need to use unsigned (&donuts)
    // and unsigned(&cups)
    cout << "cups value = " << cups <<"\t";
    cout << " and cups address = " << &cups << endl;
     return 0;

}

结果如下：
