Can you include header files in header files?

Can you include header files in header files?

3 Answers. Yes, this will work. Note, however, that if you include a lot of headers in this file and don’t need all of them in each of your source files, it will likely increase your compilation time.

How do I add #include to Stdafx H?

It’s interesting that the trick that I use isn’t in the answers:

1. Create stdafx. h and stdafx.
2. Go to project properties -> precompiled headers. Change to “use”.
3. Go to stdafx. cpp, right-click properties -> precompiled headers.
4. Go to project properties -> advanced; change “Force include files” to stdafx.

Should you include in header files?

This rule means that if the header uses a type — such as ‘ FILE * ‘ or ‘ size_t ‘ – then it must ensure that the appropriate other header ( h> or for example) should be included.

Can you # include ” stdafx.h ” for?

It’s not really a problem. Just don’t include that header. Or if you must (if you have dozens of files and you don’t want to modify them all), you can “fake” it by creating a blank file named “stdafx.h”. Can I know what is #include “stdafx.h” for? When you #include a header file, it’s sort of like copy/pasting that header file into the cpp file.

How to create a precompiled header in stdafx.cpp?

Change the settings for the stdafx.cpp file in all configurations; set the value “Create (/Yc)” for the “Precompiled Header” option. Now we have enabled the precompiled headers option. If we run compilation now, the compiler will create the *.pch file.

Is the default MSVs header stdafx.h?

MSVS likes to name the default precompiled header “stdafx.h”. But that’s all it is. It’s worth noting that precompiled headers are completely worthless unless you are seeing slow compile times. I avoid them unless they make a significant difference in compile time.

What does the / YC switch do in stdafx.h?

This file is built with the “/Yc” switch which is used specifically to tell the compiler to create precompiled headers. The stdafx.cpp file can contain one line: #include “stdafx.h”. The most interesting stuff is stored in the “stdafx.h” file.
