[問題] #define的問題
開發平台(Platform): gcc
問題(Question)： 目前情況是我有8個#define
#define A1 '1'
#define A2 '2'
#define A3 '3'
#define A4 '4'
#define A5 '5'
#define A6 '6'
#define A7 '7'
#define A8 '8'
但是我想要改一個做法,透過一個#define INPUT
#define INPUT 0x12345678
然後這8個#define可以從INPUT裡面取得上面我想要的結果
我有想過一個方法 但是失敗了
#define A1 (((INPUT>>28)&0xf)+48)
#define A2 (((INPUT>>24)&0xf)+48)
#define A3 (((INPUT>>20)&0xf)+48)
#define A4 (((INPUT>>16)&0xf)+48)
#define A5 (((INPUT>>12)&0xf)+48)
#define A6 (((INPUT>>8)&0xf)+48)
#define A7 (((INPUT>>4)&0xf)+48)
#define A8 (((INPUT)&0xf)+48)
所以想請問大家有沒有其他的方法, 謝謝.
餵入的資料(Input)：#define 0x12345678
預期的正確結果(Expected Output)：
可以和
#define A1 '1'
#define A2 '2'
#define A3 '3'
#define A4 '4'
#define A5 '5'
#define A6 '6'
#define A7 '7'
#define A8 '8'
有一樣的效果
謝謝...
