指针数组与数组指针

#include<iostream>
using namespace std;


int main()
{
int *ptr[5];//指针数组
int p=5,p2=6,*page,*page2;
//page=&p;
//page2=&p2;
//ptr[0]=&p;
//ptr[1]=page2;
//cout<<*ptr[0]<<endl;
//cout<<*page<<endl;
//cout<<*ptr[1]<<endl;


int test[2][3]={{1,2,3},{4,5,6}};
int test2[3]={1,2,3};
page=&p;
page2=&p2;
ptr[0]=&p;
ptr[1]=page2;
int (*a)[3],(*b)[3];//数组指针
a=&test[1];
b=&test2;
cout<<*page<<endl;
cout<<(*a)[0]<<(*a)[1]<<(*a)[2]<<endl;
cout<<(*b)[2]<<endl;
return 0;
