②编译指定的头文件目录(由gcc -I参数指定,工程中通常写在makefile中,避免每次编译时都要指定) ③gcc的环境变量CPLUS_INCLUDE_PATH(gcc的环境变量主要包括include环境变量和库文件环境变量,分别在编译和链接时使用。) ④最后搜索gcc的内定目录:/usr/include;/usr/local/include;/usr
#include <future> 在C++中,<atomic> 是一个标准库头文件,它包含了 std::atomic 类,这是一个原子操作库。要在C++代码中包含这个库,你需要在文件的开头添加以下代码: 代码语言:cpp 复制 #include<atomic> 在C++中,<filesystem> 是一个标准库头文件,它包含了 std::filesystem 类,这是一个文件系统库。要在...
Header Files 头文件 *.h 头文件 头文件的所有内容,都必须包含在 #ifndef {Filename} #define {Filename} // {Content of head file} #endif 头文件中的 #ifndef/#define/#endif 防止该头文件被重复引用 指一个头文件在同一个cpp文件中被include了多次,这种错误常常是由于include嵌套造成的。 比如:存在a....
