这个program会print什么出来，可以解释一下简单的逻辑为什么会print那个单词吗

#include<stdio.h>
void function (char **);
int main ()
{
char *arr[] = { "ant," "bat," "cat," "dog," "egg," "fly" };
function (arr);
return 0;
}
void function (char **ptr)
{
char *ptr1;
ptr1 = (ptr += sizeof (int))[1];
printf ("%s\n", ptr1);
}

牛逼，考眼力的
"ant," "bat," "cat," "dog," "egg," "fly"这是1个字符串

首先，这个代码是跑不起来的，就不用考虑会pirnt什么

建议修改代码，让它跑起来再说
