编译原理课程设计总结报告

1.设计题目及相关内容

本课程设计完成的是递归下降分析法。对算术表达式和赋值语句进行语义分析并生成四元式序列。其中，本设计用C语言对简单的pascal语言子集编制一个编译程序。语义分析输入的是语法分析后提供的单词串，而语法分析的输入是词法分析的程序所提供的单词序列。要求把语法分析程序和词法分析都作为子程序调用，其中输入字符串要用文件操作。

2．运行环境（软、硬件环境）

硬件环境：方正电脑，P4CPU，512M内存

软件环境：Visualc++6.0

3．算法设计的思想

本设计题目的实现，使用了多个程序，包括语义分析，语法分析和词法分析。

-Principles of curriculum design to compile a summary report

1. The design of the subject and related content

This course is designed drop recursive analysis. Of arithmetic expressions and assignment statements and generate semantic analysis of quaternion sequence. Among them, the design of a simple C language pascal language subset of the preparation of a compiler. Semantic analysis is parsing the input after the word string, and parsing the input lexical analysis procedure is provided by the word sequence. Procedures require parsing and lexical analysis are called as a subroutine, which enter the string to use file operations.

2. Operating environment (software and hardware environment)

Hardware environment: PC Founder, P4CPU, 512M memory

Software Environment: Visualc++6.0

3. Algorithm design thinking

　　　The realization of the design subject, the use of a number of procedures, including semantic analysis, syntax analysis and lexical analysis.
