Example: char **pa; 可以重寫為 char *(*pa);
若 pa = 0x1000;
*(pa+0) : 0x1000 ----> [0x009a]
*(pa+1) : 0x1002 ----> [0x009f ]
*(pa+2) : 0x1004 ----> [0x00a3]
//address value
[0x009a] = B
[0x009b] = O
[0x009c] = O <-----*(*pa)+2
[0x009d] = K
[0x009e] = '0'
[0x009f] = Y
[0x00a0] = O <-- *(*pa+1)+1
[0x00a1] = U
[0x00a2] = '0'
[0x00a3] = T
[0x00a4] = E
[0x00a5] = S
[0x00a6] = T <--- *(*pa+2)+3
[0x00a7] = '0'
[0x1000] = 0x009a <-- *pa
[0x1002] = 0x009f <-- *(pa+1)
[0x1004] = 0x00a3 <-- *(pa+2)
[0x????] = 0x1000 <-- pa
