此为编译原理实验报告 学习消除文法左递规算法,了解消除文法左递规在语法分析中的作用 内含 设计算法 目的 源码 等等.... 算法:消除左递归算法为: (1)把文法G的所有非终结符按任一种顺序排列成P1,P2,…Pn 按此顺序执行 (2)FOR i:=1 TO n DO BEGIN FOR j:=1 DO 把形如Pi→Pjγ的规则改写成 Pi→δ1γ δ2γ … δkγ。其中Pj→δ1 δ2 … δk是关于Pj的所有规则; 消除关于Pi规则的直接左递归性 END (3)化简由(2)所得的文法。即去除那些从开始符号出发永远无法到达的非终结符的 产生规则。

对c语言的简单语法分析器 文件说明: input.txt内为输入的源程序,包括for,while和if else控制等 output.txt内为输出的二元单词序列 k.txt为关键字表 l.txt为运算符和界符表 i.txt为该输入的源程序的标志符 c.txt为常数表 个别表需要序列号,这时各表的序列号默认为从1开始,每行加1。 使用说明: 在提示符下输入input.txt文件的路径和文件名字, 运行完成后,打开文件output.txt看结果。

Addfilter is a command-line application which adds and removes filter drivers for a given drive or volume. It is intended to demonstrate how to insert a filter driver into the driver stack of a device. The sample illustrates how to do this by using the SetupDi APIs. The sample works on both x86 and Alpha platforms. It has only been tested in a 32-bit environment. Since Addfilter is not a driver, it does not deal with Plug and Play or Power Management.

手机文件浏览程序的另外一个版本! SMan is a system utility that manages your UIQ device. It provides functionality which manufacturers did not provide or which are difficult or impossible to do manually. SMan helps keep your UIQ device running in a "healthy" state and, to a certain degree, allows you to customize the system behaviour of your device.

The ICA/BSS algorithms are pure mathematical formulas, powerful, but rather mechanical procedures: There is not very much left for the user to do after the machinery has been optimally implemented. The successful and efficient use of the ICALAB strongly depends on a priori knowledge, common sense and appropriate use of the preprocessing and postprocessing tools. In other words, it is preprocessing of data and postprocessing of models where expertise is truly ne

Have you ever wanted to copy a file from your Desktop Computer to your handheld Pocket PC? This included any Windows CE version too? Well if so, I will present an easy way to do it here: It s called the Remote Application Programming Interface, or, RAPI in this article. It is touched on in the MSDN but not really explained very well.

The goal with this project was to make it possible for almost any mobile-phone to use ICQ and be able to communicate with other users! One other goal with this project was to lower the GPRS-traffic in the phone and make the ICQ-ing cheaper. A third goal was to make this service as easy to log-in to as possible. Anyone tried to fill a log-in screen with a WAP-browser should know what I mean. With Wapmess all you have to do is to write your login-url ONCE and then bookmark it in your phone, to make it available fast. :)
