编译原理 课件 蛮实用的

PL/0语言的词法分析，主要是将每个词识别并且读入-PL/0 language lexical analysis, mainly to identify each word and read

词法分析程序，可对以下的C源程序进行分析：main() {int a[12] ,sum for(i=1 i=1 j--){ if(i==j&&i+j==13)sum+=a[i][j] } } printf("%c",sum) }-lexical analysis procedures, right below the C source code analysis : main () (int a [12] [12], the sum for (i = 1 ilt; I = 12) (for (j = 1 JLT; J = 12) Scanf ( "% d", a [i] [j])) for (i = 12 IGT; a = i--) (for (j = 12 IGT; = 1 j--) (if (i == ji j == 13) sum = a [i] [j])) printf ( "% c", sum

从源程序文件中读取有效字符和并将其转换成二元组机内表示形式输出。-Read from source file characters and the effective and converted into binary machine express the form of group output.

c语言实现，slr(1)语法分析，语法分析的ation表和goto表分别用txt文档保存。-c language, slr (1) grammar analysis, grammar analysis ation table and goto table txt documents were preserved.

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. In light of the semester created software engineering courses The experimental curriculum design process requirements in the software engineering idea to organize the development process. in the software life cycle stages to. Due to the smaller size of the curriculum design, the software life cycle appropriate to consolidate, streamline and five stages that the

一个slr(1)的 语法分析器 可以自行输入文法-1 slr (1) parser can enter your own grammar

词法分析和语法分析的程序，带实验报告- The lexical analysis and the grammar analysis procedure, brings the test report

C编译器,在VC6.0环境下开发，是C的一个简单编译器，但可以运行任何C程序，可以函数嵌套-C compiler, the environment VC6.0 development is a simple C compiler, But can run any C program can be nested function

这是一个文法分析器，很方便，只要输入句子，程序会自动分析，如果错误也会提示-It s a grammer analyzer,which is convenience,if you input sentence,program will automatic analyse and clue to if it is error.

词法分析器的一个实验报告 附带的有一个词法分析器 新手可以随便看看!-lexical analyzer in a report experimental fringe of a lexical analyzer novice can easily see!
