一个简单的编译器，里面有测试代码，希望对大家有用

正则式到有穷自动机 最近刚学了编译原理 搞出来得这个东西-to DFA has recently compiled a study of the principles of producing more things

这个是编译原理的词法分析的实验报告！很不错，希望大家支持！-this principle is to compile the lexical analysis of the experimental report! Quite well, and hope that we support!

LL(1)文法使用的是确定的自顶向下的分析技术。LL(1)的含义是：第一个L表明自顶向下分析是从左向右扫描输入串，第2个L表明分析过程中将使用最左推导，1表明只需向右看一个符号便可决定如何推导，即选择哪个产生式(规则)进行推导。-LL (1) grammar using a set top-down analysis techniques. LL (1) the meaning is: the first one L shows a top-down analysis is a scan input string from left to right, the first two L shows the analysis process will be the most left-derivation, one that will be just right to see a sign can decide how to derive, choose what Production (rules) for derivation. LL (1) grammar, followed by calculation of the discriminant needs FIRST sets, FOLLOW sets and SELLECT set, and then determine whether to LL (1) grammar, the last sentence further analysis.

对简单的C程序或者Pascal程序进行词法分析以TOKEN字的形式放入结果文件-of simple C program or Pascal procedures lexical analysis in the form of the word TOKEN Add outcome document

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

JC1.0。本编译器包含完整的文档与程序。借助 Lex & Bison, masm 开发。语句5个，支持混合运算。输入输出作为两个 IO 语句（函数调用），由汇编实现并编译为 io.obj，将由 Link 链接。生成 EXE。整个流程完整清晰，代码易读。-JC1.0. The compiler includes complete documentation and procedures. With Lex Bison, can develop. Statement 5, support mixed computing. Input and output as two IO statement (function call), compiled by the compiler to achieve and io.obj will link Link. EXE generation. The entire process, complete and clear, legible code.

PL/0语言可以看成PASCAL语言的子集，它的编译程序是一个编译解释执行系统。PL/0的目标程序为假想栈式计算机的汇编语言，与具体计算机无关。 文件说明: PL.htm---PL/0语言基本原理 pl0.h---定义 PL0.cpp---实现 testPl0.cpp---使用方法举例 testPas.txt---一个LP/0语言源程序-PL/0 language may regard as the PASCAL language the subset, its compiler is a translation explanation execution system.
