求大神解决    是哪里出错了   我用的是VC6.0  错误提示warning C4005: 'SWAP' : macro redefinition

 while(wFlag <= rFlag)
    {
        if(color[wFlag]==WHITE)
            wFlag++;
        else if(color[wFlag]==BLUE)
        {
            SWAP(bFlag, wFlag);
            bFlag++; wFlag++;
        }
        else
        {
            //你的程序里这里的while写错了，细心点
            while(wFlag<rFlag && color[rFlag]==RED)
                rFlag--;
            SWAP(rFlag, wFlag);
            rFlag--;
        }

    }

你的while单词写错了

哦买噶  我检查了半天都没注意太无语  没想到是单词错  谢了哈

哈哈
