C - 3D 数组两列之间的地址差异

### 3D 数组中列地址差异的探索

c
#include 
int main() {
    int arr[3][3][3];
    int (*ptr)[3][3] = arr;
    printf("Address of arr[0][0][0]: %p%
", &arr[0][0][0]);
    printf("Address of arr[0][1][0]: %p%
", &arr[0][1][0]);
    printf("%
Address difference between arr[0][0][0] and arr[0][1][0]: %lu%
", (unsigned long)(&arr[0][1][0]) - (unsigned long)(&arr[0][0][0]));
    return 0;
}
