摘 要 C语言是国际上广泛流行的计算机高级程序设计语言，在各类高等院校的计算机及相关专业中，C语言均被列为一门必修的基础课程。随着计算机技术的日趋成熟，该课程的考核从传统手工阅卷走向计算机自动评阅。本文开发的C语言在线考试系统，一方面实现了C语言课程考试的无纸化，节约了大量能源；另一方面，实现了部分题目的自动评阅，降低阅卷的工作量，提高评阅过程中的公平性与准确性。它为C语言教学提供了一套完备的自我测试系统，也为学生的自主学习提供了更好的支持。 本系统主要对考试系统中的自动组卷、考生考试及自动评分模块进行了研究与设计，我主要完成的是自动评分模块的功能实现。在设计系统的过程中，我们结合平时使用软件的需求，对该项目进行了界面的优化，该系统设计成功后，经过了一定量的测试，初步证明运行稳定，自动评分准确，评分标准统一，整体效果良好，具有一定的的使用价值。 关键字：C语言在线考试系统；自动评分模块；PHP；Apache  Abstract C language is widely popular international high-level computer programming language, various institutions of higher learning in the computer and related professions, C language are classified as a compulsory basic course. As computer technology matures, the course of the assessment from the traditional manual scoring toward the computer automatically marked. This development of the C language online examination system, on the one hand to achieve a paperless examination of the C language curriculum, saving a lot of energy; the other hand, to achieve some of the subject automatically marked, reducing the workload of marking, the process of improving Review fairness and accuracy. It is a C language teaching provides a complete self-test system, but also for the students self-learning provides better support. This system is mainly for automatic generation of test systems, and automatic scoring module exam candidates conducted research and design, I mainly to complete the automatic scoring module function implementation. In the process of designing the system, we usually use the software combines the needs of the project was carried out to optimize the interface, the system is designed successfully, after a certain amount of testing, preliminary evidence of stable operation, automatic scoring accurate, unified scoring criteria, the overall effect is good, has a certain value in use.
