Implementing function outside struct
I have this code where I have declared a struct with some functions. Trying to write the function implementation outside the struct declaration and do not know how to proceed.

Code:
#ifndef ParseEl_hh
#define ParseEl_hh

#include <iostream>
#include <fstream>

#include "DynBaseObj.hh"
#include "List.hh"
#include "Stack.hh"
#include "Tree.hh"
#include "Vect2.hh"
#include "Vector.hh"
#include "String.hh"
#include "common.hh"

enum TypeParse { PARAM, LIST };

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

struct ParseEl {

  enum TypeParse Type;
  int  Hash;
  String  Str;
  String  Name;
  List<String>  StringList;
  List<int>  Ord;

  ParseEl() { }

  ParseEl(
    const String&  name,
    String&  s,
    const List<int>&  ord) {

    Name = name;
    Str = s;
    Type = PARAM;
    Ord = ord;
    Hash = Name.Hash();

    while ((Ord.size() > 0) && (Ord[Ord.size()-1] == 0)) {
        Ord.Delete(Ord.size() - 1);
    }

  }

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

  ParseEl(
    const String&  name,
    const List<String>&  ls,
    const List<int>&  ord) {

    Name = name;
    StringList = ls;
    Type = LIST;
    Ord = ord;
    Hash = Name.Hash();

    while ((Ord.size() > 0) && (Ord[Ord.size()-1] == 0)) {
      Ord.Delete(Ord.size() - 1);
    }

  }

  ParseEl(const ParseEl&  parsel ) {

    Name = parsel.Name;
    Type = parsel.Type;
    Str = parsel.Str;
    StringList = parsel.StringList;
    Ord = parsel.Ord;
    Hash = parsel.Hash;

  }

  friend  int  operator == (
      const ParseEl  p1,
      const ParseEl  p2) {

      return (    (p1.Hash == p2.Hash) && (p1.Type == p2.Type)
          && (p1.Name == p2.Name)  && (p1.Ord == p2.Ord)
          && (p1.Str == p2.Str) && (p1.StringList == p2.StringList) );

  }

};

#endif

I have now changed the code and things are working fine. My last problem is how to take care of ParseEl() { } to be outside the struct. It is not doing anything so I suppose I can just declare it inside the struct as ParseEl();

Code:
#ifndef ParseEl_hh
#define ParseEl_hh

#include <iostream>
#include <fstream>

#include "DynBaseObj.hh"
#include "List.hh"
#include "Stack.hh"
#include "Tree.hh"
#include "Vect2.hh"
#include "Vector.hh"
#include "String.hh"
#include "common.hh"

enum TypeParse { PARAM, LIST };

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

struct ParseEl {

// -- Attributes -----------------------------------------------------------------------------------

  enum TypeParse Type;
  int  Hash;
  String  Str;
  String  Name;
  List<String>  StringList;
  List<int>  Ord;

// -- Operations -----------------------------------------------------------------------------------

  ParseEl() { }

  ParseEl(
    const String&  name,
    String&  s,
    const List<int>&  ord);

  ParseEl(
    const String&  name,
    const List<String>&  ls,
    const List<int>&  ord);

  ParseEl(
    const ParseEl&  parsel);

  friend int operator  == (
    const ParseEl  p1,
    const ParseEl  p2);

};

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

  ParseEl::ParseEl(
    const String&  name,
    String&  s,
    const List<int>&  ord) {

    Name = name;
    Str = s;
    Type = PARAM;
    Ord = ord;
    Hash = Name.Hash();

    while ((Ord.size() > 0) && (Ord[Ord.size()-1] == 0)) {
        Ord.Delete(Ord.size() - 1);
    }

  }

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

  ParseEl::ParseEl(
    const String&  name,
    const List<String>&  ls,
    const List<int>&  ord) {

    Name = name;
    StringList = ls;
    Type = LIST;
    Ord = ord;
    Hash = Name.Hash();

    while ((Ord.size() > 0) && (Ord[Ord.size()-1] == 0)) {
      Ord.Delete(Ord.size() - 1);
    }

  }

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

  ParseEl::ParseEl(
    const ParseEl&  parsel) {

    Name = parsel.Name;
    Type = parsel.Type;
    Str = parsel.Str;
    StringList = parsel.StringList;
    Ord = parsel.Ord;
    Hash = parsel.Hash;

  }

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

  int  operator == (
    const ParseEl  p1,
    const ParseEl  p2) {

    return (    (p1.Hash == p2.Hash) && (p1.Type == p2.Type) && (p1.Name == p2.Name)
             && (p1.Ord == p2.Ord) && (p1.Str == p2.Str) && (p1.StringList == p2.StringList) );

  }
