本程序不能编译除大小写字母之外的编码 本程序需事先建立字母权值文后件才可运行 本程序从文件中读入文字，编译后写入文件，所以屏幕上不会直接出现答案...

这个是编译原理的词法分析的实验报告！！很不错，希望大家支持-this principle is to compile the lexical analysis of the experimental report! ! Quite well, and hope that we support! !

一个外国人写的词法分析程序，大家可以参考一下，不过代码太多了！ 有点难-a foreigner writing lexical analysis procedures, we can take a look, but too many of code! Hard

语义分析器，将语义分析程序编制成子程序，在语法分析器分析出各语法单位后，分析其含义，并将可执行语句或表达式翻译为四元式输出，并将错误信息输出。-Semantic analyzer, semantic analysis program compiled subroutines, in the parser analyzes the syntax of the unit, analyze its meaning, and translated into an executable statement or expression quaternary-output, and error information output.

编译原理中的First集与 Follow集生成程序，这是我用C＋＋语言写的，希望对大家有点用处。-Compiler Principle of First Set and Follow procedures set generation, which is my C++ languages, we hope to somewhat useful.

前些天写了个小语言的词法分析程序，因为前些天在VC知识库看到一个pascal词法分析的程序，觉得写得挺复杂的。其实词法分析程序的原理都是一样的，所以我想只要搞明白了简单的词法分析程序，再写复杂的就不难了，无非是多加几个关键字，多写几个条件判断语句而已。词法分析是编译程序的基础，也是最简单的。好，现在让我们看程序吧。 先让我们看看这个小语言的文法吧-few days ago wrote a small language lexical analysis procedures, because the other day in the knowledge base to see a VC pascal lexical analysis procedures, find that quite complex. In fact, lexical analysis procedure is the same principle, I think if you understood a simple lexical analysis procedure to write complex it is not difficult, is nothing but add a few keywords and writing several conditions judgment statement it. Lexical analysis is the basis of compilers, as well as the most simple. Well, now let us look at the procedures it. Let us look at this small language grammar it
