Does it matter if I add the #include directive to my cpp file or to the header file with the included content?

Question

My C ++ program uses a separate header file (let him call it myHeader.h) and therefore includes it ( #include "myHeader.h"). In my program, I need to use a different header file (let him name it another.h). Does it matter whether I put the directive #include "another.h"in a cpp file or in myHeader.h?

Answer 1

If it is not used in the file .h, then there will be no difference in success / failure of compilation.

However, it is recommended that you include include for header files that you only need to implement in files .cppfor the following reasons:

• - , .
• A.h B.h , B.h include A.h. .
• , ( , , ).
