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：
