比dos下的debug更好的debug程序源码- Compared to under dos debug better debug procedure source code

这是一个vc++环境下运行的编译原理的词法分析源程序，可以在vc++环境下直接运行，其中有运行的截图，学校要求做实验报告，给和我一样要交报告的人。-This is a vc environment compiler running under the principle source of lexical analysis, the vc direct operating environment, which is running the screenshots, the school asked to do experiments, and I like to have to pay the people.

这是一个用C++编写的编译原理的词法分析程序,希望对各位学习编译的同学有一定帮助-This is a C compiler prepared by the tenets of lexical analysis procedure, and I hope to learn from you and the compiler will definitely help students

编译原理语法分析器编程- The translation principle grammar analyzer programs

现将本人搜集常用的程序设计语言的词法和形式文法提供给大家。其中，词法是按LEX格式编辑，形式文法是按YACC格式书写，大家可直接用LEX和YACC工具编译生成各类程序设计语言的分析器。-commonly used programming language syntax and grammar forms to the public. Among them, morphology is based on LEX format editing, grammar form is written by YACC format, we can use the LEX and YACC tools various compiler generation programming language analyzer.
