1、整个系统均用C语言实现；

2、利用指针、链表来实现学生成绩的数据结构设计；

3、系统具有输入、显示、查询、删除、排序、插入，保存、读取基本功能；

4、系统的各个功能模块都用函数的形式来实现；

5、可以将学生成绩信息保存在文件中。

6、可以将学生信息从文件中读取出来。-one, the entire system will be used C language; 2, the use of indicators, Listless to achieve student performance data structure design; 3, the system is input, display, query, delete, sort, insert, preservation, read basic functions; 4, the various functional modules are used in the form of function to achieve; 5. student achievement will be to preserve information in the document. 6, students will be information from the document read out.
