例6.1 通過(guò)指針變量訪問(wèn)整型變量。
#include <iostream>
using namespace std;
int main( )
{int a,b;                                  //定義整型變量a,b
int *pointer_1,*pointer_2;                //定義指針變量*pointer_1,*pointer_2 
a=100;b=10;                               //對(duì)a,b賦值
pointer_1=&a;                             //把變量ａ的地址賦給pointer_1
pointer_2=&b;                             //把變量ａ的地址賦給pointer_2
cout<<a<<″ ″<<b<<endl;                    //輸出a和b的值
cout<<*pointer_1<<″ ″<<*pointer_2<<endl;  //輸出*pointer_1和*pointer_2的值
return 0;
