Should I include common routines members in one "include header" or use separate header for each class?

[imakaia]

I have a big project with many classes in diferent files including their methods in diferent files also.

I have some RAF manipulation routines functions which are put in each class as members

1ST OPTION
Till now I declare them inside the class and i include a header outside them.
A diferent file for each class but all containing the same routines.
e.g

1 2 3 4 5 6 7 8 9 10 11

class SERVER { bool writeINT(string Filename, size_t pBlock intSTRUCT iCELL ); }; #include "routines.SERVER.h" class EXECUTOR { bool writeINT(string Filename, size_t pBlock intSTRUCT iCELL ); }; #include "routines.EXECUTOR.h" routines.SERVER.h

bool SERVER:: writeINT(string Filename, size_t pBlock, intSTRUCT iCELL ) {...} routines.EXECUTOR.h ---------------------------------------------------- bool EXECUTOR::writeINT(string Filename, size_t pBlock, intSTRUCT iCELL ) {...}

2ND OPTION
I can also just declare them with no parametres and include the same header on both
e.g.

1 2 3 4 5 6 7 8 9 10 11

class SERVER { bool writeINT(); #include "routines.h" }; class EXECUTOR { writeINT(); #include "routines.h" }; routines.h

bool writeINT(strinf Filename, size_t pBlock, intSTRUCT iCELL ) {...}

In this option however i lose the ability to see the parametres of each function. I can put them as comments however

Thats the best solution if there ll be changes No? What do you suggest?

Can I get another risk this way i dont see?
(writing include is as to copy-paste the file contents in that place no? no other program binding yes?)

I suppose what you want to know, is about inheritance?

Don't do that. I didn't quite understand what exactly you're trying to achieve, but I doubt any good solution would include including headers in random places.

[imakaia]

OH YES I CAN DONE IT THROUGH INHERITANCE ALSO!

THATS PRODUCTIVE AND PROFESSIONAL!

HOW CAN I HAD FORGOT!

Thank you so much. I doubt there are other solutions. I ll leave it Unsolved 24 hours however.

@hanst99
Many classes will use common routines like
Deep_Copy_This_Specific_Structure_Common_to_all_Clases
(STRUC sourceSTRUCT, STRUCT destinationSTRUCT);

I'm glad I could help! :)
