学生成绩管理系统 c++实现

系统可以实现如下功能：

1.录入：可以录入学生基本信息（姓名、学号）学生各门课程的成绩（五门）

2.查询：可以查询任意学生任意一门功课的成绩

可以查询全班最高和最低分数

可以查询全班任意一门课程的平均分

3.删除：可以删除任意学生的成绩信息

4.修改：可以修改任意一个学生的信息

要求：根据以上功能说明，设计学生成绩信息、系统的存储结构、设计程序完成功能。根据要存入一个数据文件中永久保存。

提示：

1.数据的存储结构可以采用线性结构

2.每次系统运行前先从文件中取数据，运行结束之前把数据存入文件

3.每个学生的信息采用结构体

4.从磁盘中读入学生的信息到内存中采用函数

5.把内存中的学生信息输出到磁盘文件中采用函数 -Student achievement management system c++ implementation

System can achieve the following functions:

1 Entry: Students can input basic information (name, student number) students in various courses of the results (five)

(2) query: You can check any one any student homework results

You can check the class the highest and lowest scores

You can check any class of a course of average

3 Delete: You can delete any information on student achievement

4 Review: You can modify any of the information a student

Requirements: Based on the above functional descr iption, design student achievement information, the system s storage architecture, the design process completion. According to the data file into a permanent preservation.

Tip:

1 data storage structure can be linear structure

2 each time the file system before running start to take data, run before the end of the data stored in files

3 each student s information using a structure

4 students read from disk into memory
