武汉理工大学编译原理课程实验源代码之词法分析器

编译原理的作业 编译器- Translation principle work compiler

编译原理的VC实现,最近做编译作业,下载的.-compile VC tenets of a recent compiler operations, the downloaded.

C programm for frequency distribution.

lcd的初始化等-lcd initialization, etc.

有限自动机的运行，利用状态表和有限自动机的运行原理，识别一个输入串是否为一个有效的无符号定点实数。-of the operation, the use of tables and limited state of the automatic machine operation principle, to identify whether an input string as a symbol of effective non-sentinel real.

不需要做任何修改的lex-yacc的demo，可以在parser generator或lex-bison下成功运行-Do not need to make any changes to the lex-yacc the demo, or a parser generator in the lex-bison successfully running

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.

1、输入串应是词法分析的输出二元式序列，即某算术表达式“实验项目一”的输出结果。输出为输入串是否为该文法定义的算术表达式的判断结果。 2、LL(1)分析过程应能发现输入串出错。 3、设计两个测试用例（尽可能完备，正确和出错），并给出测试结果。 -1, input strings should be the output of lexical analysis of binary sequence, that is, the arithmetic expression of a

语义分析的功能： 第一，审查每个语法结构的静态语义，即验证语法结构合法的程序是否真正有意义。有时把这个工作称为静态语义分析或静态审查。第二，如果静态语义正确，语义处理则要执行真正的翻译，即，或者将源程序翻译成程序的一种中间表示形式（中间代码），或者将源程序翻译成目标代码。 有报告-Semantic analysis of the functions: First, review each of the grammatical structure of the static semantics, that is, the grammatical structure to verify whether the procedures legally meaningful. Sometimes this is called static or static semantic analysis review. Secondly, if the correct static semantics, semantic processing should be the implementation of a genuine translation, that is, or will be translated into procedures source an intermediate representation (intermediate code), or source code translated into object code. There are reports
