程序代码：

#include <iostream>
using namespace std;
int  main()
{
    int *p1=new int;
    *p1=12;
    int *p2=new int;
     *p2=12;
    cout<<"（赋予p1指针的值）"<<*p1<<endl;
        cout<<"（12也有地址?）"<<p1<<"（地址是否一样）"<<&p1<<endl;
        cout<<"（测试2赋予p2指针的值）"<<*p2<<endl;
            cout<<"（测试2也有地址?）"<<p2<<"（测试2地址是否一样）"<<&p2<<endl;
    delete p1;
    delete p2;
    system("pause");
    return 0;
}
