衝啊！pointer！

今日主題：指標與二維陣列（續）

接續昨天的議題，今天來看個範例。

#include <stdio.h>

main()
{
    int arr[3][2] = {100,200,300,400,500,600};
    int i;
    
    for (i = 0; i < 3; i++){
        printf("arr[%d] = %p\n", i, arr[i]);
        printf("arr+%d = %p\n", i, arr+i);
        printf("*(arr%d) = %p\n\n", i, *(arr+i));
    }    
}

結果如下：

arr[0] = 0x7fff43520df0
arr+0 = 0x7fff43520df0
*(arr0) = 0x7fff43520df0

arr[1] = 0x7fff43520df8
arr+1 = 0x7fff43520df8
*(arr1) = 0x7fff43520df8

arr[2] = 0x7fff43520e00
arr+2 = 0x7fff43520e00
*(arr2) = 0x7fff43520e00
