C语言+数据结构学期课程设计《员工管理系统》

资源内容介绍

关于一个员工管理系统的开发，详细描述了如何构建一个具备基本功能的员工信息管理软件。系统的核心目标是有效地组织和维护员工的个人及工作相关数据，确保数据的准确性和易于访问性。系统的主要特点包括：员工信息管理：每个员工的记录包含编号、姓名、性别、出生日期、学历、职务、电话号码和住址。数据持久化：系统能够将员工数据保存到文件中，以便在程序关闭后数据不会丢失，并且在下次启动时能从文件中恢复这些数据。数据检索：支持按ID或姓名查找员工的具体信息。数据更新：允许管理员根据员工的编号修改其个人信息。数据录入：具备添加新员工信息的功能。数据移除：可以按员工编号删除不再在职的员工记录。数据排序：能够按照员工的ID、姓名或出生日期对所有员工信息进行排序。数据展示：可以列出所有员工的信息，或者展示排序后的员工列表。在技术实现上，文档采用了C语言编程，并利用了动态顺序表作为存储结构，这使得数据的增删改查更加高效。此外，还设计了一系列函数来实现上述各项功能
