本文介绍了我如何使用.h和.cpp?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在尝试在.h和.cpp中格式化它。我不确定应该怎么做。这就是我所拥有的。另外,我不确定如何处理WeatherMeasurement。谢谢
C ++代码:
I am trying to format it in the .h and .cpp. I am not sure how it is really supposed to be done. here is what I have. Also, I am not sure what to do with WeatherMeasurement. Thank you

我尝试过:
我是编程的新手,所以我甚至不知道如何启动它。
What I have tried:
I am new to programming so I am not even sure how to start it.
推荐答案
它是c语言和C ++中的惯例单独的代码,以提高可读性。在一个h。 file是函数,类和常量的声明。并且在cpp-files中是标头声明内容的实现。
您的WeatherMeasurement文件为空。为WeatherMeasurement编写一些代码是你的工作。
您应该看到这个 C ++初学者教程学习基础知识或阅读一些入门级C ++书籍以获取开始。
提示:学习编写清洁代码并使用类。
It is convention in the language c and C++ to seperate code for better readability. In a h. file are the declaration of functions, classes and constants. And in the cpp-files is the implementation of the declared stuff of the header.
Your WeatherMeasurement files are empty. It is your job to write some code for "WeatherMeasurement".
You should watcht this C++ beginners tutorial to learn the basics or read some entry level C++ book to get started.
Tip: Learn writing "Clean Code" and use classes.
