编译原理及实践课后答案及部分代码，要的自己下-Compiler Construction Principles and Practice of after-school and part of the answer code

上课时老师用过的SNL编译器- Attends class when teacher has used SNL compiler

这个语法分析器用到的是自顶向下的递归调用的方法，根据Cminus语言的文法规则 的BNF范式编写递归调用的代码，parse方法是程序的入口，它调用的stmt_sequence完成整个语法分析工作，stmt_sequence背后是12个互相调用的方法，它本身也在语法分析的过程中被调用到。 每个方法在最后会返回一个构造好的节点DefaultMutableTreeNode节点t给调用它的方法，然后调用它的方法用这个返回的节点继续构造，最后语法分析完成后会返回一棵完全构造好了的树节点，然后将这个树节点作为根节点生成一个树控件JTree显示到窗体程序上 -CMM 　parser

Pascal语言的词法分析器源程序和开发文档，用LEX编写，可作为编译原理课程的学习参考，源文件已编译通过-Pascal language lexical analyzer and source documentation, prepared with LEX, as compiler theory courses of study reference source documents compiled by

一种视频流H264压缩加密方法

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

手工完成C语言编写的C-词法分析器，列出源代码以及提取出的token串-Manually written in C language C-lexical analyzer, listing the source code, and extract the token string

用递归下降法分析算术表达式的框图，主要完成： ⑴ 通知外界键入算术表达式； ⑵ 控制Ｅ过程分析算术表达式； ⑶ 根据分析结果之正误，分别通知外界不同的信息。 -Analysis of recursive descent method with arithmetic expressions diagram, mainly to complete: ⑴ notice outside type arithmetic expressions ⑵ control process analysis arithmetic expression E ⑶ results are based on an analysis of error, respectively, different information to inform the outside world.

构造实验一所给文法（应考虑改造）的FIRST集合和FOLLOW集合；构造LL(1)分析表；构造预测分析的总控程序；利用分析表、分析栈和总控程序对源程序进行自上而下的语法分输出整个语法分析过程中栈的变化过程及分析结果，如符合语法规则输出“正确”，否则输出“错误”。 -Experiment to construct a grammar (should consider the transformation) of FIRST and FOLLOW set of the collection construct LL (1) analysis table structural prediction analysis of the master control procedures the use of analytical tables, analyze the stack and the total source code control procedures carried out since the last sub output down syntax parsing process of the whole stack and analysis of the results of the change process, such as the grammatical rules out the " right" , otherwise output " error."
