摘要
网络课程C语言编程学习中,师生互动性差、教学效率低,学生难以凭借自身能力解决编程中常见的代码缺陷问题.为了更好帮助学生解决学习中的难题,辅助老师达到教学目的,研究一款代码缺陷检测辅助学生编程实践系统.该系统首先对易犯的代码缺陷分类,分析编译器不易检测的语法、词法和语义缺陷;然后构建智能分析器,集成多种检测工具,在系统中存储知识规则集合并扩展常见代码缺陷抽象模式;最后检测代码并给出错误报告和修改意见,通过配合学生模型辅助学生编程学习.实验结果表明:该系统能成功检测出常见代码缺陷并辅助学生编程实践.
In the learning of online course C Language Programming, the interaction between teachers and students is poor, and the teaching efficiency is low. It is difficult for students to solve the common code defects in programming themselves. To better help students solve the problems in learning and assist teachers to achieve the teaching purpose, this study develops a practical system to assist students in programming. Firstly, the system classifies the common code defects, focusing on the analysis of syntactic, morphological, and semantic defects that are not easy to detect by the compiler. Secondly, it builds an intelligent analyzer that integrates a variety of detection tools to store the set of knowledge rules and extend the abstract pattern of common code defects. Finally, it detects the codes and gives error reports and modification suggestions. This system is capable of assisting students in programming by cooperating with the student model. The experimental results show that the system can successfully detect common code defects and thereby assist students in programming practice.
