自己用vc编写的班级学生成绩管理系统，成绩存储在txt格式的文件中...

我们设计的数据库系统能够实现学生信息管理，学生成绩管理等功能。我们研究了数据库的查询优化问题。-we design a database system to achieve student information management, student performance management capabilities. We have studied the database query optimization problem.

一、课程设计题目、内容、要求 题目：《学生成绩管理系统》(第二套 难度：2) 内容：按要求完成的基础上，增加了输入学号查询学生记录的功能，和错误输入报错功能 要求： 1）输入将本班学生的信息（每个学生至少包括学号、姓名、科目成绩（三门）、学分、平均分）。 A．要求编写函数sort对个学生按某个条件（比如某科成绩，学号，学分）升序或降序（可选择）排序，并将结果（包括名次、学号、姓名、成绩、学分、平均分）显示出来。 B．编写函数find，用折半法查找某科某个成绩，并将结果打印出来。 C．要求编写函数fun找出所有及格的同学，并将他们的信息存显示出来。 -a curriculum design topic, and requested topic : "Student Performance Management System" (second difficulty : 2) : completed as required, on the basis of increase in the importation of Science inquiry student record function, input errors and mistakes in the functional requirements : 1) importation of Bumbuna student information (including each school students at least, names, subjects results (3), credits, average). A. Prepared function sort of a student by a certain condition (such as certain subjects, learning, credits) ascending or descending (optional) sequencing, and the results (including the rank of school, names, achievements, credits, average) is displayed. B. Prepared function
