这是编译原理的词法分析源程序

一个简单实用的自己编写计算器，非常非常非常好用。-Calculator

C语言词法分析器 by wpc_LK 这是一个简单的词法分析器，不能避免的存在错误请大家指出予以纠正，谢谢！ 示例语句 include int main{ int a=3,b=4,c if((a+b)==7)c=1 else c=0 return 0 } 输入 exit 退出程序。-C language lexical analyzer by wpc_LK This is a simple lexical analyzer can t avoid that there re some errors here,please correct, thank you! for exzample: include int main{ int a=3,b=4,c if((a+b)==7)c=1 else c=0 return 0 } input exit quit the program.

用C语言实现了C-程序的语法分析，以控制空格来显示层次，表示出了语法分析树-With the C language to implement the syntax of C-program analysis in order to control the space to show the level of expressed syntax parse tree

是用flex分析pl0源代码的程序，统计处其中所有的关键字和变量名称，这个rar文件中有readme，具体见其中的说明。另外还有2个测试文件ceshi1.pl0和ceshi2.pl0-is flex pl0 source code analysis procedures, the Census and Statistics Department in which all the keywords and variable names, the rar a readme file, as shown in the note. Another two tests and documents ceshi1.pl0 ceshi2.pl0

simple语言的词法和语法分析，包括token串的填写，符号表的填写，四元式的生成 -simple language morphology and syntax analysis, including token strings fill in, fill in the symbol table, the generation of type Quaternion

LCC4.2 C编译器源码，移植到VC6.0平台下，可将C代码，编译为80X86的汇编代码，C文件为99.C，汇编程序保留在98文件中。强烈推荐 C编译器源代码，构件自己具有专业，产品级水平的C编译器。-LCC4.2 C compiler source, the transplantation of VC6.0 platform can be C code, the compiler to compile code 80X86, C document 99.C, assembler retained in the 98 documents. Strongly recommended C compiler source code, their professional components, product level C compiler.

(1)构造文法G的LR(0)项目 (2)构造文法G的LR(0)项目集规范族及识别活前缀的DFA (3)证明文法G不是LR(0)文法而是SLR(1)文法，并构造SLR(1)分析表 (4)设计LR语法分析程序，且能输出分析过程 (5)列举两个例子测试语法分析程序（识别失败一例，识别成功一例，后者推导步骤不得少于10步） -(1) construct grammar G of the LR (0) item (2) construct grammar G of the LR (0) item sets standards and identification of family living prefix DFA (3) prove that the grammar G is not LR (0) grammar, but the SLR (1 ) grammar, and constructs SLR (1) analysis table (4) design LR parser, and can output analysis process (5) cited two examples of parsing test procedures (identification fails an example, identify the success of a case, the latter shall not be derived step Less than 10 steps)
