PL/0语法分析程序原代码（TURBOL PASCAL）

词法分析程序的功能是，接受一个表达式，输出该表达式中的各类单词符号。测试词法分析程序时，可以按照一定格式输出各类单词符号。 本程序实现整数四则运算表达式的词法分析程序。-Lexical analyzer function is to accept an expression, the output of the expression of the various types of word symbols. Testing lexical analysis program, you can format the output according to certain types of word symbols. This procedure to achieve an integer 4 expression is the lexical analysis program.

这是一个关于词法语法分析器的软件，我们的课程设计的，-This is one of the syntax analyzer software, the curriculum design,

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

这是很好的编译原理的词法分析程序。供大家参考！

压缩文法等价变换，输入一个文法，可以对其进行等价变换，很方便-compression grammar equivalent transformation, importation of a grammar can transform its equivalent, is a convenient

生成C++的词法/语法分析的Flex语法分析器 -Flex syntactic and phrase parser which can produce C++ code

我的编译原理大作业，自动分析语法，判断语句是否符合规则。DFA即有穷自动机。因为这个工作量比较大，所以恕我不无帐号发放了。-I build large operating principle, automatic syntax analysis, judgment statement with the rules. DFA that the DFA. Because the workload is bigger, it is not without regret that I paid the account.

一个语法分析，能实现SLR语法分析，是一个好的语法分析器-A parsing,which can realize SLR parsing,is a good parsing analyzer.
