我有点看法,但不知道是否正确.
因为参与计算的源数据都是单字节,结果也是单字节
所以,先取pos最后8位,
pos & 0xFF的结果不就是pos吗
那么是不是可以简化为(tmp-pos)^pos

(tmp-(pos & 0x000000FF)) ^ (pos & 0x000000FF)

其中，tmp是源文件的数据，单字节
pos是文件指针的当前位置
结果就是解码后的数据，单字节

那你就先计算pos & 0x000000FF，然后再计算好了。

因为 pos & 0x000000FF出现了两次
所以,我认为应该可以简化运算.过程并不重要,关键运算越简单,速度越快.
请各位算法高手帮忙

这式子用于C++对文件进行解码
修正一下应该如下：
(tmp - (pos &0x000000FF)) ^ (pos & 0x000000FF)
但我编写的解码程序比原来的明显慢
所以
我怀疑我的算法有问题

如果这个表达式能够很好的表达意图，就不需要简化

看不出为什么要简化

已经解决,最后化简为 (tmp-(short)pos) ^ (short)pos
但是，这不是导致速度慢的原因。主要原因是文件读写问题。
将文件一次性读进内存，然后在内存解码，再一次性写到文件。
速度快很。
谢谢大家。

linux服务器开发-socket小结
linux服务器开发入门版-socket小结 一、服务器/客户端构建流程 服务端函数调用流程： socket->bind->listen->accept->recv/send->close 客户端函数调用流程： socket->connect->send/recv->close send/recv可以进行多次交互。 1.服务端在listen之前，客户端不能向服务端发起连接请求 2.服务端在调用listen之后，服务端的socket开始监听客户端的连接 3.
