"《编译原理》课程设计说明书：if-else条件语句的简单优先法翻译程序设计"

本课程设计要求学生设计一个IF-ELSE条件语句的翻译程序，采用简单优先法，输出四元式。学生首先需要写出符合给定的语法分析方法的文法和属性文法，然后完成中间代码四元式的描述。接着，学生需要根据给定的语法分析方法的思想，完成语法分析和语义分析程序设计。在编制分析程序后，学生需要设计若干用例，并进行上机测试，确保程序的准确性和有效性。最后，学生需要按照要求书写课程设计报告，包括系统描述、文法及属性文法的描述、语法分析方法描述、中间代码形式的描述、编译系统概要设计、详细算法描述、软件测试方法和结果、研制报告等内容。通过这次课程设计，学生将深入理解编译原理相关知识，并掌握实际应用的能力。Designing a program for translating IF-ELSE conditional statements using the simple precedence method and outputting quadruples is the main task of this course project. Students are required to first write a grammar and attribute grammar that conforms to the given syntax analysis method, then describe the quadruples of the intermediate code. Next, based on the idea of the given syntax analysis method, students need to complete the design of syntax analysis and semantic analysis programs. After developing the analysis program, students need to design several test cases, conduct on-site testing, and ensure the accuracy and effectiveness of the program. Finally, students are required to write a course design report according to the specified requirements, including system description, description of grammar and attribute grammar, description of syntax analysis method, description of intermediate code form, outline design of compilation system, detailed algorithm description, software testing method and results, development report, etc. Through this course project, students will gain a deeper understanding of compiler principles and acquire practical application skills.
