C ++标题顺序 [英] C++ Header order

问题描述

在header / cpp文件中应该声明什么顺序头文件？显然，后续头文件所需的那些应该更早，类特定的头文件应该在cpp范围而不是头文件范围，但是有一个设置顺序约定/最佳实践吗？

What order should headers be declared in a header / cpp file? Obviously those that are required by subsequent headers should be earlier and class specific headers should be in cpp scope not header scope, but is there a set order convention / best practice?

推荐答案

在头文件中，你必须包含所有的头文件，使其可编译。

In a header file you have to include ALL the headers to make it compilable. And don't forget to use forward declarations instead of some headers.

在源文件中：

• 相应的头文件


• 必要的项目标题


• 第三方库标题


• libraries headers


• 系统标题

• corresponded header file
• necessary project headers
• 3rd party libraries headers
• standard libraries headers
• system headers

按此顺序，您不会错过任何头文件忘记包含自己的图书馆了。

In that order you will not miss any of your header files that forgot to include libraries by their own.
