最后没有显示员工摘要的问题

Question

我一切正常，但当我在上交之前去检查它时，出了点问题，我无法让它在最后运行员工摘要。有人可以指导我了解我在这里缺少的部分吗？我还不断收到 3 个警告 C$@$$ "=" 从 double 转换为 float 可能丢失数据？第 99、101 和 109 行？：

Answer 1

(1) 我在 MSVC 2010 下编译/运行了它，但没有收到类型警告。但是，警告问题可能是因为您混合了类型——工资、基本工资和加班工资都是浮点类型，并且您正在使用 int 类型的变量进行计算（文字 40 和小时） a - 使用 40f 而不是 40（使用浮点常量而不是 int）和 b - 在这些语句中使用 static_cast(hours) 而不是仅 hours c - 考虑使用 double 类型而不是 float - 无论如何，使用 double 类型可以获得比 float 类型更好的精度。

正如 Mornfall 所说，您永远不会调用 AddSomethingUp 成员函数。

对该函数的唯一引用是类描述中的原型头和实际代码本身——你不能在任何地方调用它。

你可以在奶牛回家之前构建函数式代码，但除非你真的在某个地方告诉程序运行它，否则它不会被执行。您需要在处理完员工数据之后以及从 main 执行“return”语句之前调用它。

这是使用某些版本的 Visual Studio 编写的，以下几行是致命的赠品：

// ConsoleApplication29.cpp : Defines the entry point for the console application.`
//
#include "stdafx.h"

您是否尝试在调试器下运行它以查看调用了哪些代码？

Answer 2

您永远不会致电Addsomethingup，因此它永远不会打印摘要。将双精度数转换为浮点数当然会失去精度。始终对所有变量使用浮点数或双精度数（即，除非您有充分的理由不这样做，否则不要混合这些变量，而您可能在这里没有这样做）。
