条件，如果一个字节中1的中间有0,这样的位也要被置1,

例如，

一个字节为：#01001100B转化为#01111100B

谢谢了。

也许对你们身经百战的工程师们是不难，是我涉世太浅，想了大半天，还是没有思路。肯请你不吝赐教。

我也是初学的。有个很笨很笨的想法：
现判断这个数是不是：0000 0000，0000 0001，0000 0011， 0000 0111，0000 1111， 0001 1111， 0011 1111， 0111 1111， 1111 1111， 1000 0000，1100 0000，1110 0000， 1111 0000， 1111 1000， 1111 1100， 1111 1110？也就是两端是否有1.有可能有更好的方法，期待...

然后 MOV A,direct
XRL A,#0FFH
ORL A,direct

新手学习中，拍两砖。

你这方法也不行。你想判断八位就得用到255次判断。可我实际用的时候是12位的。那程序写到哪去了都？

否则就逐位扫描吧

LS 的方法有BUG哦，而且也不见得快

如果我数是12位的呢。比如 110011000000 转换成 111111000000，这怎么办？也写个表？

错了，忽略了许多数据。抱歉。

只看该作者 · 2008-12-12 15:43

数据先放在A中，B为转换后结果
    MOV  B,#11111111B
SHL:PUSH ACC
    MOV  R7,#80H
LP1:RLC  A
    JC   SHR
    XCH  A,R7
    XRL  B,A
    RR   A
    XCH  A,R7
    CJNE R7,#80H,LP1
SHR:POP  ACC
    MOV  R7,#01H
LP2:RRC  A

试了一下，感觉还是用流程图说起来方便点。
不过先点下：
1    先从最低位开始检测直到测到1，置标志，并记下为第几位。
2    再往高位测，测到0，则记下前一位（为1）
3    再往高位测，测到1，补齐中间0位。
4    再往高位测，如2 3步。
具体编程时可用循环方式，有多少位，没多少次。在由0变1与1变为时作相应处理。
如果还不大明白，晚上我再上流程图。

先把结果填充全1，右望，遇到0,把结果对应的位清零，直到遇到1，停止；
同理，左望，遇到0,把结果对应的位清零，直到遇到1，停止；
左望右望完了，就可以输出结果。

    填充全1： 1 1 1 1 1 1 1 1

右望  -->     0 0 1 0 1 0 1 0     <--  左望

       结果： 0 0 1 1 1 1 1 0

一个循环就够了，循环只计算高位的0，屏蔽低位的0只需&(val | -val)即可。
unsigned int change (unsigned int val) {
    if (val == 0)
        return 0;
    unsigned int result = (unsigned int) -1;
    unsigned int tmp = val;
    while ((int) tmp > 0) {
        result >>= 1;
        tmp <<= 1;
    }
    return result & (val | -val);
}
