词法分析程序，很初级的，我们刚刚开编译原理- Lexical analyaer, very primary, we just opened the translation principle

用C语言编的一个小解释器，可以执行C程序的！算是可以执行C程序的C程序吧！ （大师）写的哦！- A small interpreter arranges which with the C language, may carry out the C procedure! Is may carry out C the procedure C procedure! (Master) writes oh!

编译原理实验中的工具BISON,可以再windows或者DOS下使用-Compilation Principle Experiment tools BISON, can be used under windows or DOS

自己写的一个simple语言scanner，也许有些错。可作参考。-a scanner of simple language writed by myself,maybe it has error.you can consult.

1.1 引言 1.1.1 设计目的 本次课程设计是在完成一个学期的编译原理课程之后，为了进一步加深对编译原理相关知识的理解，培养实际解决问题的能力而进行的。结合本学期所开设的软件工程课程，本次课程设计实验过程要求按照软件工程的思想来组织开发过程，按照软件生命周期的阶段划分来进行。由于课程设计规模较小，所以对软件生命周期进行适当的合并，简化为五个阶段，即需求分析、总体设计、详细设计、编码实现和测试。 1.1.2 设计任务 针对本次课程设计我们设计了一个简化的pascal语言，称为mini-pascal。设计的任务就是开发出针对mini-pascal语言的编译程序。标准的编译程序结构分为五部分，分别是词法分析、语法分析、语义分析和中间代码生成、优化和目标代码生成。由于时间和能力所限，我们的编译程序只包括前三个部分，最后生成四元式形式的中间代码。 -1.1 Introduction 1.1.1 design purpose of this course is designed to complete a semester of compiler theory courses , in order to further deepen the knowledge of compiler theory understanding, develop practical problem-solving skills into practice.

C_minus语言的BNF语法定义 程序由声明的列表(或序列)组成，声明可以是函数或变量声明，顺序是任意的。至少必须有一个声明。接下来是语义限制(这些在C中不会出现)。所有的变量和函数在使用前必须声明(这避免了向后backpatching引用)。程序中最后的声明必须是一个函数声明，名字为main。注意，C－缺乏原型，因此声明和定义之间没有区别(像C一样)。-C_minus BNF language syntax definition of procedures from the list of statement (or sequence), with a statement can be variable or function statement, the order is arbitrary. There must be at least one statement. Next is the semantic constraints (these will not arise C). All the variables and functions to be used in the statement (which avoids the use Backpatching backwards). Procedures must be the last statement is a function declaration, the name of the main. Attention C- lack of a prototype, and the definition of a statement is no difference between (the same as C).

这是个简单的语法分析器程序,输入一个表达式,会给出一个分析过程.-This is a simple procedure syntax analyzer, the importation of an expression, is an analytical process.
