用C＋＋实现职工工资管理要求代码完整且能运行 基本要求： 定义职工（employee）类，其中至少包括姓名、性别、工号、电话、所在科室和工资。 功能要求： 1、设计菜单实现功能选择： 2、输入功能：输入职工信息，并保存到文件中： 3、查询功能： 1）能够根据工号精确查询职工信息： 2）能够根据姓名、科室查询职工信息 3）分科室进行工资统计，计算各科室的平均工资 4、根据职工的工资排序输出 5、根据工号修改职工信息 6、根据工号删除职工信息

以下是一个简单的职工工资管理系统的C++代码，满足您的基本要求和功能要求：

使用方法：

1. 将以上代码保存为`employee.cpp`
2. 编译代码：`g++ employee.cpp -o employee`
3. 运行程序：`./employee`

注意事项：

1. 程序会在当前目录下创建一个`employees.txt`文件来保存职工信息。
2. 请按照程序要求输入职工信息，否则程序可能会出错。
3. 程序没有做输入检查，如果输入不合法可能会导致程序崩溃。
