说明：  计一个学生成绩管理系统，需要存储4个班级的数据结构成绩，存储学生信息使用结构体。用到的数据结构是线性表，包括顺序表以及链表。 2.按成绩降序存储，考虑存储完所有信息以后再进行排序，或者在存入的时候进行排序，排序方法可以使用比较法，冒泡排序等方法。 3.系统有输入信息，插入信息，合并信息，输出信息等功能，所以应该有一个界面框供用户选择。 4. 要实现顺序表以及链表的建立、初始化、输出、查找、定位的功能。
(For a student achievement management system, it needs to store the data structure scores of four classes, and store the student information using structure. The data structure used is linear table, including sequence table and linked list. 2. It is stored in descending order according to the results. It is considered to sort after all the information is stored, or sort when it is stored. The sorting method can use comparison, bubble sorting and other methods. 3. The system has the functions of inputting information, inserting information, merging information, outputting information, etc., so there should be an interface box for users to choose. 4. Realize the function of establishing, initializing, outputting, searching and locating the sequence list and the linked list.)
