    从键盘读入一个四位的十六进制数,CRT显示等值的二进制数. 由于每个十六进制数位对应4个二进制,所以每读入一个十六进制位后,即可将其对应的4个二进制位依次输出。由于数字‘0’~ ‘9’的ASCⅡ码为30H~39H,字母‘a’~‘f’与 ‘A’~‘F’的ASCⅡ码为61H~66H 与41H~46H ,因此,如果输入的字母为数字‘0’~‘9’,则其低4位即为对应的二进制位;如果输入的字符为字母‘a’~‘f’或‘A’~‘F’,则需要减7,然后通过移位将低4位依次输出。 -Reading from the keyboard into a 4 hexadecimal number, CRT display equivalent binary number. Since each hexadecimal number of the corresponding 4-bit binary, so every time into a hexadecimal places, can be its corresponding 4-bit binary sequence output. Due to the number
