编译原理

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.

我做的一个C子集的词法分析器可以分析C语言的一个子集,包括17个关键字以及绝大部分的符号.能正确的报错-I do a C subset of the lexical analyzer can be analyzed in a C language subset, including 17 keyword majority of the symbols. Able to correct errors

自己做的一个普通词法分析程序c语言环境终结符：e c j t u可扩展-have done an ordinary lexical analysis procedure c language environment End Address : c j e t u scalability

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

输入文法，可以实现对非终结符，终结符的判断，最后判断文法。-importation of grammar can be realized by the end of the non-Fu, Fu end of the judgment, the final judgment of grammar.
