这是我们老师留的作业，还算不错我给完成了，希望给想做的朋友一点启发...

词法分析的程序设计- Lexical analysis programming

语法分析的功能： 语法分析是编译过程的核心部分，它的主要任务是按照和程序语言的语法规则，从由词法分析输出的源程序符号串中识别出各类语法分析成分，同时进行语法检查，为语义分析和代码生成作准备。 有报告-Parsing functions: syntax analysis is the core of the compiler process, its main tasks and procedures in accordance with the grammatical rules of language, from the output by the lexical analysis of source symbols to identify all types of string parsing components, at the same time syntax checker for semantic analysis and code generation to make preparations. There are reports

reading from file and display the number of words without spaces

自己写的一个编译程序，可以从二进制文件中读取一段c程序，进行表达式的识别和一些简单的c语句，最后生成三元式输出-To write a compiler, you can read from the binary files for some c procedures, identification and expression of c some simple statements, the last generation of ternary output

一个很号用的词法分析程序，望能对想熟悉编译原理的同仁有一定的帮助，谢谢支持-one of the very lexical analysis procedures can look familiar to colleagues compiler theory can help, thank you support

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.

很详细的ll1文法编译演示程序,学习编译的极品!-very detailed grammar compiler ll1 Demonstration Program, the study compiled Acura!

一个小语言的词法分析器，由此可以写出其他各种语言的词法分析器。这对编译原理的初学者或许有一定的帮助。-a small language lexical analyzer, it can be written in various languages other lexical analyzer. This compiler theory and beginners may be of some help.

一个实现词法分析的程序 VC++环境 所需的efile.pas rfile.pas和头文件 仅供参考-achieve a lexical analysis procedure required for the VC environment and efile.pas rfile.pas document is the first reference

一个写得很不错的C编译器，供需要写编译器的人参考一下。-A very good C compiler, the compiler of supply and demand of people to write reference.
