编程思路：①: 使用单链表实现本程序要求，单链表每个节点存储一个学生的信息。②: 创建一个链表类（List），链表类可实现如下功能：创建链表，插入节点，删除节点，编辑节点，显示节点，保存链表信息等功能，读入数据文件等功能（详细说明请查看源代码）。③: 创建一个操作类（Operater），操作类实现如下功能：显示菜单，操作链表。-programming ideas :　: use a single linked list to achieve the procedural requirements of each node-Chain store a student information.　: Creating a List category (List), objectlist can achieve the following functions : Create List, insert nodes, the nodes to delete, edit nodes, nodes showed that the preservation Chain information and other functions, read features such as data files (see detailed descr iption of the source code).　: creating a category of operation (Operater), the operation to achieve the following functional categories : display menu, operation List.
