我一直在为这个课程编写课程，但是我的输出无法正确。
我的作业指示是：</ p>
扩展员工薪资计划，以包括基于小时和薪水的员工。此阶段使用一组员工对象，不同类别员工的继承以及薪水计算的多态性。给出了52周的年薪以及以薪水为基础的员工的加班时数。
对于基于工资的员工，要找到一周的常规（总）工资，将工资除以52.要计算基于工资的员工的加班工资，首先通过将总工资除以40来找到每小时工资，然后计算加班费。对于每位员工，还必须计算加班费，税额和净工资。
此外，该计划应该找到所有员工的最低和最高净工资，并根据他们的净工资（升序）对员工进行分类
这就是我到目前为止所做的：

当我在CMD中运行我的程序并为2名员工输入时，第二名员工将覆盖第一名员工。我不确定有什么问题，任何帮助或指导都会非常感激（我之前找不到这个问题，但我认为它已经存在，我是一名新生并且不熟悉Stack Overflow）。
答案 0 :(得分：0)
初始化employeeCounter并且它将起作用：
int employeeCounter = 0;
坦率地说，这段代码根本就不存在。你需要至少一致地缩进它。你需要注意很多事情。
您应该浏览C++ Core Guidelines。

您有全局变量来存储数据，而在打印函数中，您正在打印这些全局变量。这意味着您只能获得最新的存储值。
你真的需要通过OOP的基础知识来正确处理这些事情。
始终缩进代码。 初始化变量。 并且，不要评论每行代码。
