Library creators should put their headers in a folder and have clients include those files using the relative path #include <some_library/common.h> The advantages of the angular form listed below assume that a library's headers are put into such a "root" folder named after the library (I hate it when libraries don't do that).
#include "filename" The preprocessor also searches in an implementation-defined manner, but one that is normally used to include programmer-defined header files and typically includes same directory as the file containing the directive (unless an absolute path is given).
Is there any material about how to use #include correctly? I didn't find any C/C++ text book that explains this usage in detail. In formal project, I always get confused in dealing with it.
In C (or a language based on C), one can happily use this statement: #include "hello.h"; And voila, every function and variable in hello.h is automagically usable. But what does it actually do? I
If a library is included in a class header and then this header is included in another class do I have to include the library again? For example: #ifndef A_H #define A_H #include<someLibrary....
As the title suggest I am looking for a way to do a where clause in combination with an include. Here is my situations: I am responsible for the support of a large application full of code smells.
Include is used to extract use case fragments that are duplicated in multiple use cases. The included use case cannot stand alone and the original use case is not complete without the included one. This should be used sparingly and only in cases where the duplication is significant and exists by design (rather than by coincidence).
0 I propose to simply include an All.h in the project that includes all the headers needed, and every other .h file calls All.h and every .c/.cpp file only includes its own header.
I am using Visual Studio Code in my C++ project. I installed Microsoft C/C++ Extension for VS Code. I got the following error: #include errors detected. Please update your includePath. IntelliSense
In the project where you want to #include the header file from another project, you will need to add the path of the header file into the Additional Include Directories section in the project configuration. To access the project configuration: Right-click on the project, and select Properties. Select Configuration Properties -> C/C++ -> General.
