C语言课程设计 Win32应用程序

问题描述：

请设计一个职工信息管理程序，以方便人事部门对本单位职工的管理，该程序应该具有以下功

能：

(1)能从键盘输入职工的信息。

(2)给定职工号，显示职工的信息。

(3)给定工作部门，显示该部门的职工信息。

(4)给定职工号，修改职工的信息。

(5)给定职工号，删除职工信息。

题目要求：

(1)按照分析、设计、编码、调试、测试的软件过程完成这个应用程序。

(2)职工信息应该包含职工号、姓名、工作部门、职称、入厂时间、工资。

(3)为程序设计windows 窗口，在该窗口上以按钮的形式为用户提供“菜单”，通过点击各个功

能项对应的按钮完成操作。

输入要求：

(1)用户可以根据需求，选定相应的操作项目。进入每个操作后，通过窗口的文本框，从键盘输

入相应的信息。程序根据用户输入的信息完成相应的处理，实现要求的功能。

(2)能对输入的数据进行简单的校验，例如，入厂时间必须是合法的日期格式，职工号是唯一的

（一个职工号对应一个职工的职工信息）。

输出要求：

(1)应用程序运行后，要在屏幕上显示一个按钮形式的“菜单”。

(2)要求用户输入数据时，给出清晰、明确的提示信息，包括输入的数据内容、格式以及结束方

式等。

(3)在程序完成处理后，要清楚地给出程序的处理结果。例如，在给定职工号删除职工信息时，

如果该职工不存在，要提示没能删除，如果删除成功要提示删除成功。

实现要求：

(1)在程序中使用链表存储职工信息。

(2)采用模块化程序设计的方法，将程序中的各项功能用函数实现。

提示：

(1)使用结构体表示职工信息，一个结点保存一条职工信息。

扩展功能：

(1)提供一些统计功能。例如统计每个部门的人数，统计平均工资、统计各职称的人数。

(2)职工信息从文件读入。

(3)将职工信息保存到文件中。

代码如下：

 #include <windows.h>

 #include<string.h>

 #include<stdio.h>

 #include"resource.h"
