职工工资管理系统设计--C语言课程设计

1、.C语言程序设计课程设计实习报告实 验 题 目 职工工资管理 1问题描述：添加模块：添加职工或工资的信息删除模块：能通过姓名或者工号删除职工信息修改模块：修改职工信息查询模块：能通过姓名或者工号查询职工信息显示模块：显示全部职工信息文件管理模块：负责源数据文件的管理，包括新建、读取和保存源数据2概要设计 职工工资管理添加模块删除模块修改模块查询模块显示模块文件管理模块按姓名按工号按姓名按工号新建记录数据文件读取记录数据文件保存记录数据文件在各模块处用指针函数来使用后面的保存记录数据文件进行保存。3详细设计 include <stdio.h># include <stdlib.
