怎么用C语言实现职工工资管理系统

本文小编为大家详细介绍“怎么用C语言实现职工工资管理系统”，内容详细，步骤清晰，细节处理妥当，希望这篇“怎么用C语言实现职工工资管理系统”文章能帮助大家解决疑惑，下面跟着小编的思路慢慢深入，一起来学习新知识吧。

设计要求：

模拟并设计一个企业的职工工资管理系统，职工信息包括工号、姓名、基本工资、津贴，设职工人数不超过500人，以菜单选项的方式完成相应的功能，主要功能需求如下：

建立工资表；

职工扣税和实发工资；

按实发工资从高到低的顺序显示工资明细表；

修改职工的工资信息；

按工号查询职工工资信息；

职工工资统计分析；

退出系统。

基本思路：

将职工工资管理系统的职工信息录入功能、数据处理并存入文件功能、按照职工工号查找职工工资信息功能、修改职工信息功能分成多个模块，为了使程序的可读性更强，程序的编写将以函数形式编写封装各个功能，然后在主函数中以循环形式读取用户输入的指令，根据用户的指令选择不同的函数入口地址，从而执行不同的操作，实现设计要求的职工工资管理系统的各项功能。
