指针数组

顾名思义：用来装指针的数组

#include <iostream>

using namespace std;

int main()
{
    /**********************指针数组************************/
    int arr[3] = {10,100,200};
    int length = sizeof(arr) / sizeof(int);
    int *p_arr[3];

    for(int i = 0;i < length;++i)
    {
        p_arr[i] = &arr[i];
    }

    for(int i = 0;i < length;++i)
    {
        cout << "address : " << p_arr[i] << endl;
        cout << "value : " << *p_arr[i] << endl;
    }
    return 0;
}

输出如下：

address : 0x61fef8
value : 10        
address : 0x61fefc
value : 100       
address : 0x61ff00
value : 200
