C语言实现的SIMPLE语言词法分析器，并用JAVA实现界面。

一个小型的编译程序，用于学习实验。 文件中包含有 词法分析 语法分析 编译程序等 -Compile a small program for learning experiment. File contains lexical analysis parser compiler, etc.

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.

一个程序，用于判定给定的文法是否为算符优先文法。 实现了：1．文法的机内表示；2. FIRSTVT集和LASTVT集的计算； 3. 算符优先关系矩阵的构造。-a procedure for the determination of grammar to whether the operator priority to grammar. Realized : 1. Grammar said the machines; 2. LASTVT FIRSTVT sets and set computing; 3. Operator precedence relations of the matrix structure.

计算机科班学生的词法分析作业，用flex处理生成的VC源程序。- The computer regular professional training student s lexical analysis work, processes the production with flex the VC source program.

词法分析程序。用于词法分析器的制作与应用。-lexical analysis procedure. Lexical analyzer for the production and application.

朋友给的一个产品的demo程序，说是对学单片机的朋友极其有用-Friend to a product demo program, saying it was for school SCM extremely useful to Friend

输入已经消除左递归的以及提取公共左因子的LL(1)文法，再输入相应的表达式，若分析成功，则在递归输出过程中输出"acc",若不成功，则有相应的报错以及位置指名。注意，要把同一个非终结符的产生式分成单个输入。他会自动计算first,follow,预测分析表的构造，但并不输出。-importation has been eliminated and left recursive public from the left-LL (1) grammar, further importation of the corresponding expression, if the analysis is successful, the output of the recursive process output "belongs", if successful, there were errors and the corresponding location named. Attention, we should end with a non-escalation of production into a single input. He will be automatically calculated first, follow, and predicting and analyzing the table structure, but does not export.
