编译原理的一个题目：算符优先分析-Compilation Principle of a topic: operator priority analysis

词法分析程序设计 1、给出各单词符号的类别编码。 2、词法分析程序应能发现输入串中的错误。 3、词法分析作为单独一遍编写，词法分析结果为二元式序列组成的-Lexical analysis program design one, given the various types of code word symbols. 2, lexical analysis procedure should be able to detect errors in the input strings. 3, again as a separate lexical analysis prepared for morphological analysis of binary sequence composed of

编译原理的词法分析程序-compiler tenets of lexical analysis procedure

TurboC2.0汉化包 311K 英语不太好的朋友们可以试试看。不过需要先下载一个英文版的TurboC2.0，用汉化包覆盖。-TurboC2.0 sinicizing wraps the 311K English not too good friends to be allowed to try to look. But needs first to download an English version TurboC2.0, with sinicizing package of cover.

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

使用Java语言实现Small Basic语言解释器。包括两个主要的子系统：一个是表达式解释器，负责处理数字表达式；另一个是解释器，负责程序的实际执行。-use Java language Small Basic language interpreter. Including the two major subsystems : an expression interpreter is responsible for handling digital expression; Another interpreter, responsible for the actual implementation process.

使用vc编写的文法分析器课件，对于入门的vc学习者，可以作为windows界面编程的参考-vc prepared by the use of grammar analyzer courseware for the entry vc learners, as windows programming interface reference

Java形式文法-BNF.是设计形式文法的好范例。-Java form grammar-BNF. Form design is a good example of grammar.

用词法+语法分析树写的四则运算，非常强大
