Thank you. If I include it inline, I would not need to have a .cpp file then. Is that right? Is it ok not to have a .cpp on some occasions like this one?

---------- Post updated at 05:02 AM ---------- Previous update was at 04:45 AM ----------

I had originally some code concerning a class (definition and implementation) in a header file put have now split it to have the definition and inline functions in the .h file, and the rest of the implementation in a .ccp file.

This is what I have for the .cpp file

The #ifndef, #define, #include and #endif were in the .h file. Should I remove them from the .cpp file as well, as to your explanation?

Code:

#ifndef COMPLEX_H
#define COMPLEX_H

#include <assert.h>
#include <cmath>
#include <iostream>

#include "gendef.h"

//////////////////////////////////////////////////////////////////////////

Complex&  Complex:operator /= (const Complex&  C) {
  assert((C.Re != 0) || (C.Im != 0));
  REAL  mod = (C.Re * C.Re) + (C.Im * C.Im);
  REAL  nr, ni;
  nr = ( (Re * C.Re) + (Im * C.Im) ) / mod;
  ni = ( (C.Re * Im) - (Re * C.Im) ) / mod;
  Re = nr;
  Im = ni;
  return (*this);
}

#endif
