信息登记源码
㈠ 学生信息管理系统最简单源代码。
方法一：
1、创建一个c语言项目。然后右键头文件，创建一个Stu的头文件。
㈡ C# windowform程序，求源代码。 1.计算电费 2.信息登记

㈤ 简单的JAVA员工信息管理系统源码怎么做
1）每个员工的信息包括：编号、姓名、性别、出生年月、学历、职务、电话、住址等。
（2）系统的功能包括：
（a）查询：按特定条件查找员工。
（b）修改：按编号对某个员工的某项信息进行修改。
（c）插入：加入新员工的信息。
（d）删除：按编号删除已离职员工的信息。
（e）排序：按特定条件对所有员工的信息进行排序。

㈨ 求C语言学生信息管理系统源代码
给你点建议吧，录入功能你就用scanf进行录入，浏览功能你可以遍历你的所有数据，依次输出即可，查询最简单的就是用顺序查找，排序可以采用冒泡法
