在我的C++编程类中，我负责为5名员工创建工资记录器。其中一个要求是没有全局变量，因此我认为这需要我在每个单独的函数中局部声明变量并将它们传递给它们。我知道错误意味着什么，但我不知道如何实施解决方案，请帮助。我甚至不确定是否通过引用传递/按值传递甚至对参数有意义，但由于关于doCalculations（），displayPayrollSummaryResults（）和displayEmployeeResults（）中有3个参数的3个错误， （）。这里是我有的doCalculations（）。C++编程非常新 - C++函数不需要0个参数
在调用getInput之前还有另外一个函数，其中我接收用户输入的empID，payrollType ....并将它们放入payrollArray。数组的其余部分用于存储此函数的计算数据。并在之后添加更多功能来显示结果（请参阅最后的完整代码）。

在main（）做什么用newPayroll.doCalculations（ “放什么在这里吗？”），我只是去通过试验&误差将（双payrollArray [12] [5]，诠释& empID ....），不完全保留C++课程的构造函数或函数原型，也许我缺少一些代码块？感谢您的帮助。

你有一本书，从你的班学习？ – 2012-04-18 06:03:55
这是很多代码。我建议你提供一个简短的例子来说明你的问题。 – juanchopanza 2012-04-18 06:08:46
你，先生，缺少一些基本概念。我建议你简单看看函数和方法是如何工作的。 – ScarletAmaranth 2012-04-18 06:10:03
