1. char (*p)[4]; - 聲明數p作爲指針炭的陣列4。
2. char *p[4]; - 將p聲明爲指向char的數組4。

Answer 2

char (*p)[4];：p是指向一個char陣列長度的4

      char [4] 
    points to    | 
    char [4]    v 

    +------+    +------+------+------+------+ 
    | p |------------>|  |  |  |  | 
    +------+    +------+------+------+------+ 
         char char char char 

    p will point to a char [4] array. Array is not created. 
    p is intended to be assigned at address of a char [4] 

char *p[4];：p是長度爲4的一個陣列，所述陣列的每個位置是一個指向char

   +------+------+------+------+ 
    p   |  |  |  |  | 
an array  +------+------+------+------+ 
itself   |  |  |  | 
       v  v  v  v 
       char* char* char* char* 

    p is an array and will be allocated in stack (if automatic)
