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

lupdate

lupdate(1)						      General Commands Manual							lupdate(1)

NAME

       lupdate - update Qt Linguist translation files

SYNOPSIS

       lupdate [ options ] project-file
       lupdate [ options ] source-files -ts ts-files

DESCRIPTION

       This  page  documents  the Qt Linguist Update tool for the Qt GUI toolkit.  Lupdate reads a qmake/tmake project file (.pro file), finds the
       translatable strings in the specified source, header and interface files, and updates the translation files (.ts files)	specified  in  it.
       The translation files are given to the translator who uses Qt Linguist to read the files and insert the translations.

       The .ts file format is a simple human-readable XML format that can be used with version control systems if required.

OPTIONS

       -help  Display the usage and exit.

       -noobsolete
	      Drop all obsolete strings.

       -verbose
	      Explain what is being done.

       -version
	      Display the version of lupdate and exit.

USAGE

       Here is an example .pro file that can be given to lupdate:

	   HEADERS	   = funnydialog.h 
			     wackywidget.h
	   SOURCES	   = funnydialog.cpp 
			     main.cpp 
			     wackywidget.cpp
	   FORMS	   = fancybox.ui
	   TRANSLATIONS    = gnomovision_dk.ts 
			     gnomovision_fi.ts 
			     gnomovision_no.ts 
			     gnomovision_se.ts

       When  running lupdate on this project file, the translatable strings in all the files listed in the HEADERS, SOURCES and FORMS entries will
       be put in the translation files listed in the TRANSLATIONS entry. Previous translations will be reused as far as possible,  and	translated
       strings that have vanished from the source files are marked obsolete.

       Lupdate can also be invoked with a list of C++ source files, .ui files and .ts files:

	   lupdate *.cpp *.h *.ui -ts gnomovision_dk.ts
