1. Try to avoid putting any using namespace declarations in your header files. If you absolutely need some namespace objects to get your headers to compile, please use the fully qualified names (Eg. std::cout , std::string )in the header files. 1.尽量避免将任何使用空间声明在你的头文件。
头文件 在之前介绍的大部分C语言语法基础的章节中列举的实例代码部分,都会在源文件的开始的第一行通过#include预处理指令包含进"stdio.h",后面这个".h"后缀名的就是头文件了。而什么是头文件呢? 通俗方式理解头文件 还是从"stdio.h"说起,这是C语言中内置的标准库,也就是说,头文件很多时候其实就是一个“库...
建议把头文件也加上,这样在 VS 里可以出现在“Header Files”一栏。 add_executable(main) set(sources main.cpp other.cpp other.h) target_sources(main PUBLIC ${sources}) 使用GLOB自动查找 使用GLOB 自动查找当前目录下指定扩展名的文件,实现批量添加源文件: add_executable(main) file(GLOB sources *.cpp...

Hopefully someone can help - I have spent 2 weeks trying to fix this and exhausted pages of google results :( I use a Mac mostly these days and wanted a nice "proper" IDE for Mac and VSCODE seemed to fit the bill. I have it working fine ...

例如,main.c包含了headerA.h和headerB.h,而headerA.h内部又包含了headerB.h。在预处理阶段,headerB.h的内容就会被复制到main.c中两次:一次是main.c直接包含它,另一次是通过headerA.h间接包含。 为了解决这个问题,我们需要一种机制来确保每个头文件在同一个编译单元中只被处理一次。幸运的是,C/C++ 提供了...
