摘 要
学生成绩管理系统是典型的信息管理系统,是学校教务管理的重要组成部分,其处理信息量很大。本课程设计是用C++实现对学生的成绩管理作一个简单的模拟,实质是建立学生成绩单链表,每条记录由姓名、学号与成绩组成,即链表中每个结点由4个域组成,分别为:学号、姓名、成绩、存放下一个结点地址的next域。用菜单选择操作方式完成五项功能分别写成五个函数,插入学生成绩对应建立学生单链表的功能,输出全部学生成绩记录,后三个功能分别对应单链表的查询、修改与删除三大基本操作。该系统中的数据采用线性表中的链式存储结构即单链表来存储,用结构体类型和类类型定义每个学生记录并采用外部文件方式记录数据简便数据的读取与保存。

Abstract
Student achievement management system is a typical management information system, is an important part of the school educational administration management, the large amount of information. The curriculum design is used to achieve C++ performance management for the students to make a simplesimulation, the essence is to establish students report list, each recordconsists of name,and grade, namely the linked list in each node iscomposed of 4 domains, respectively: next domain name, student number,grade, put down a node address the. Complete the five functions were written in five function menu to select the mode of operation, into the student achievement established a single list of the output function of students, allstudents record, after the three functions corresponding to single table query,modify and delete the three basic operations. The system data in the linked storage structure of linear table is a single linked list to store, use the structure types and class types define each student records and the use of an external file to read and save data and simple data record.
