使用lex yacc编译/小

一个使用flex和bison的小例子-use of a flex and bison small examples

flex，词法自动生成工具，他可以在极短时间内帮助产生编译器的词法c源程序-flex, automatically generated lexical tools in a very short time he can help the compiler generate c source of lexical

DOS-intel平台的C编译器以及z80平台的C编译器。自己人写的。还不错啊。可以用之！-DOS-intel platform C compiler and the Z80 platform C compiler. Own writing.错啊not. Can be used!

能够生成exe执行文件的vc++源代码程序，多多指教~-capable of producing documents vc implementation of the source code procedures, exhibitions ~

基于pascal的词法分析程序-based on the lexical analysis procedure

按递归下降方式设计其编译程序，生成PL/0栈式指令代码，然后解释执行。用(a=1)+2*(b=3+4*5)/2+2*a*b-(a=a+5)/ (c=2) 测试-dropped by recursive approach to design their own compiler, generating PL/0 Stack-code instructions, and then the interpretation and implementation. Using (a = 1) 2* (b = 3 4* 5)/2* a* b- (a = 5 a)/(c = 2) Testing

编译的作业，对词法的分析分类以及发现错误，希望与大家交流，谢谢指教-Task of Compiler Implementation,To analyse and find error of Lexical,wish to communication with you,thanks.

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.

编译原理简单优先的文法的分析，有过程，一目了然，谢谢指教。-compiler priority to the principle of simple grammar analysis, a process, clear, thank you for your excellent suggestion.
