谢谢你。

推荐答案

CDECL 报告：

char *(*arr)[2]

declare arr as pointer to array 2 of pointer to char

和

char **arr[2]

declare arr as array 2 of pointer to pointer to char

这只是在 [] 数组声明具有较高的precedence比 * 指针预选赛，所以括号改变的含义。

It's just that the [] array declarator has higher precedence than the * pointer qualifier, so parentheses change the meaning.
