我最喜欢的(我必须承认我用过很多次):

啊，我一直很喜欢这个……

public GetRandomNumber()
{
    // Chosen by a fairly rolen dice
    return 12;
}

 * As Gregor Samsa awoke one morning from uneasy dreams he found himself
 * transformed in his bed into a gigantic insect. He was lying on his hard,
 * as it were armour plated, back, and if he lifted his head a little he
 * could see his big, brown belly divided into stiff, arched segments, on
 * top of which the bed quilt could hardly keep in position and was about
 * to slide off completely. His numerous legs, which were pitifully thin
 * compared to the rest of his bulk, waved helplessly before his eyes.
 * "What has happened to me?", he thought. It was no dream....

大约10年前，我从事图像处理工作，通过扫描显微镜视频帧来检测细胞运动。我当时在做一个特别复杂的工作，决定和朋友出去喝一杯。当我回到家时，我工作了一会儿，但没有太多，因为我喝醉了。第二天早上，我发现了一个10行完全混乱的函数，带有以下注释(显然是我自己写的):

/* Ah ah ah! You'll never understand why this one works. */

最奇怪的是，它竟然起作用了。

一个文件中5000多行代码中很少的一些注释 事实上，我和那个为自己的编码风格辩护的程序员有过一次争论…… 无可奉告! 没有评论;-)(或者很少) 遗憾的是，这是产品代码。

offset=1;
for (i=0;i<=len;i++)
    {
    if ((i!=0)&&(i<len)) //-3
        {
        switch(mess[i])
            {
            case ETX:
            case ETB:
            case DLE:
                buf[offset]=DLE;
                offset++;
                break;
            }
        }
    buf[offset]=mess[i];
    offset++;
    }

我喜欢这个开关!

for (n=0;n<offset;n++)
{
    Sleep(TR);  //Modif A
    Sleep(T);//
    FWriteFile(hCom,buf+n,1,&dwMot,NULL);
    if (ECHO)
        FReadFile(hCom,tab,1,&dwMot,NULL);
}

不，没有注释解释什么“修改A”是在标题。

if (GetFileSize(hSlotFile,NULL)==3600)   //5*720

720是多少?
