符合编译原理的词法分析器

语法分析器(C++)源代码＋其详细的课程设计报告 输入的文法可以消除左递归并提取公共左因子求出文法的非终结集合――FIRST和FOLLOW集并对输入的算符优先文法，构造算符优先关系表 -Parser (C++) Source code its detailed report on curriculum design input left recursive grammar can be eliminated and the public left factor extract derived grammar of non-end collection- FIRST and FOLLOW set of the input operator priority grammar, operator precedence relations structure table

LEX程序 用来生成词法分析器-LEX procedure uses for to produce the morphology analyzer

非常好的编译源代码 将一个l语言转换为中间代码 java版本-very good source code will compile a l converted to intermediate language code java version

FIR滤波器，经过编译！！！！！！无密码，解压就可用-FIR filter, after the compiler! ! ! ! ! ! No password, decompression can be used

词法语法分析，说明说明原理的词法分析和语法分析的全过程！-Lexical syntax analysis that the principle of lexical analysis and syntax analysis of the entire process!

这是一份实验报告，目的是掌握YACC的使用方法，了解YACC处理二义性的方法。 用YACC等工具生成如下文法表示的表达式对应的计算器 exp->exp + exp | exp - exp| exp * exp |exp / exp |exp ^ exp | - exp |(exp) |NUM 对于输入的表达式，能输出结果。比如: 3 +(4 *5)结果应为23 当出现错误时可以进行错误处理。 -This is a test report, the purpose is to master the use YACC to learn YACC handling of the ambiguity approach. Using tools such as YACC grammar that generates the following expression for the corresponding calculator exp-> exp+ exp | exp- exp | exp* exp | exp/exp | exp ^ exp |- exp | (exp) | NUM expression for the input type, can be output. For example: 3+ (4* 5) the result should be 23 when the error can be error-handling.

C语言来构造编译器的,十分详细的源代码，还有注释-on the use of C language compiler construction, the site has its source code matching.
