How to create header files for later usage?

Question

I want to create header files, but I do not know where to begin.

Which reserved keywords start and end within a header file?

Its purpose is to write my own specialized file permissions, even though, I do not need to use the DWORD Windows registry keyword.

Answer 1

See Header files (C++)

Answer 2

Hi,

I want to create header files, but I do not know where to begin.

You could start from an empty project, and then add a .h file (right click the project -> add -> New Item).

Which reserved keywords start and end within a header file?

Typically, header files have an include guard or a #pragma once directive to ensure that they are not inserted multiple times into a single .cpp file.

#ifndef YOUR_NAME_INCLUDE  
#define YOUR_NAME_INCLUDE  
  
/* Your function statement here */  
#endif  

For more details about header files, I suggest you could refer to the Doc: https://learn.microsoft.com/en-us/cpp/cpp/header-files-cpp?view=msvc-160
