c++ - 结果总是返回 0 和访问类

Question

我的代码有几个问题。

首先，使用这样的代码，无论我输入什么信息，它总是返回 0，关于在哪里解决这个问题以及如何解决的任何建议？我相信这与我的类(class)员工有关。我将如何解决这个问题？

其次，如何访问 int total() 中的信息？我需要访问它以获取最后一点代码。

此外，如果您注意到我可以做些什么来优化我的程序，我欢迎您提出建议。我正在学习 C++，并将永远是一名学生。

嘿伙计们，感谢您的帮助。我现在已经完成了大部分。它正在显示所有信息。我现在正致力于让它显示员工摘要数据。我修改了我的代码以使其更清晰，因为我尝试了所有给我的建议，因为我在实践中学得最好。

Answer 1

这就是使用未初始化变量的结果。您没有为您的类(class)成员设置任何值，您不能指望编译器猜测您的员工姓名或总工资是多少。

您需要使用以下表格:

对象名.成员名=值
