c语言写的basic词法分析器

YYCC语言编译器-YYCC Language Compiler

没什么的 只是一个普通的编译原理的实验程序-it doesn t matter,it is a ordinary test program of complier pronciple

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

#include

针对java语言的最简词法分析器 输入原文件输出目标文件。txt

El-Kabong: A speedy, yet forgiving, SAX-stylee HTML parser.-El-Kabong : A speedy, yet forgiving. SAX- stylee HTML parser.

一个Pascal子集语言的编译器，将pascal子集语言的源程序存成source.txt文件，经过编译器的处理得到C++语言的code.cpp文件。-Subset of a Pascal language compiler, a subset of the pascal language source.txt Save as source files, compiler after treatment has been C++ Language code.cpp document.

这可是我的倾情制作，离卖弄的语法分析器，是自己写的实现程序，不使用他人的结果，直接从原始语法里进行推理计算的，而且这个使用c语言实现的，很多底层函数都是自己来写，像hash表里的hash函数，还有像动态自增长分配等。当然这个还很不完善，但是已经作了很多工作，差就差在没有找到理想的脚本支持语言，最后没有办法只能用函数指针的数组来进行语义调用了。-this but my DEDECATES production, from the play of parser, written in their own procedures, not to use the results of others directly from the original grammar conducted calculated reasoning, but the use of the c language, many are bottom of their function to write, like hash exterior of the hash function , as from the dynamic growth of distribution. Of course, this is far from perfect, but has made a lot of work, they just lacked the poor fail to find an ideal script language support, no way to the final only with an array of function pointers for the Semantic call.

本人写的简单C词法分析器，能基本实现C词法分析。可以供要求不是很严格的毕业设计。-I wrote a simple C lexical analyzer that can realize the basic lexical analysis of C. Can not very strict requirements for the graduation project.

本代码为根据老师的课程设计要求做的小编译器的词法分析部分和语法分析部分，附件中有老师的要求文档，还有语法分析时使用到的分析表-This code is based on the teacher" s curriculum design requirements to do a small part of the compiler" s lexical analysis and syntax analysis section, in the annex to the request of the teacher documents, as well as the use of grammatical analysis to the analysis table
