c++ - What is Error C2039 and what does it mean in this case? -

i cannot compile code due errors these:

error c2039: 'difference_type' : not member of 'player' c:\program files (x86)\   microsoft visual studio 12.0\vc\include\xutility 373 1 football simulator" error c2039: 'iterator_category' : not member of 'player'  c:\program files (x86)\   microsoft visual studio 12.0\vc\include\xutility 371 1 football simulator" 

and on.

these messages offer nothing of value on how fix code or compiler having trouble , left code cannot compile. there 1 specific problem code, , getting barrage of useless compiler errors , amidst 1 of useful error tells me actual mistake is

this stdafx.h

#pragma once  #include "targetver.h"  #include <stdio.h> #include <tchar.h> #include <iostream> #include <algorithm> #include <cassert> #include <string> #include <time.h> 

and player.h fine.

 #pragma once #include "playerattributes.h" enum position{     gk,     fb,     cb,     dm,     cm,     fw,     max_positions };   class player {     playerattributes attributes;     std::string m_sname;     int m_nage;     position m_eposition;     std::string e_steamname;  public:      player();     player(int ndesiredattributevalues);     //     player(std::string sname, int nage, position eposition);      player(std::string sname, int nage, position eposition, int ndesiredattributevalues);     ~player();      friend std::ostream& operator<< (std::ostream &out, player &cplayer); }; 

edit: , pointed below, actual error lies in file team.cpp

team::team(int nnumberofplayers, int nattributevalue){      acplayer = new player[nnumberofplayers];     std::fill(acplayer[0], acplayer[nnumberofplayers-1], nattributevalue);  // error     nteamsize = nnumberofplayers; } 

nothing useful appeared on error list , in output, 5th message stated:

1> team.cpp(13) : see reference function template instantiation 'void std::fill(_fwdit,_fwdit,const _ty &)' being compiled

how supposed identify problem this? previous method check first error , go line stated, didn't work time.

thanks.

as comment stated above, error show in visual studio output window, didn't see (for reason).

the error states this:

1>  team.cpp(13) : see reference function template instantiation 'void std::fill<player,int>(_fwdit,_fwdit,const _ty &)' being compiled 

that error points in team.cpp file:

//test slow version team::team(int nnumberofplayers, int nattributevalue){      acplayer = new player[nnumberofplayers];     std::fill(acplayer[0], acplayer[nnumberofplayers-1], nattributevalue);  // error     nteamsize = nnumberofplayers; } 

now sees it, can tell issue is. std::fill function requires iterators first 2 parameters, provided full blown objects, not iterators.

the fix this:

    std::fill(acplayer, acplayer + nnumberofplayers, nattributevalue);   

a pointer has same traits iterator satisfies conditions std::fill requires. original problem std::fill algorithm applying operator++ iterator, , since passed object has no ++ defined, error emitted.

so contrary claims in post, these not "nonsense compiler errors". error makes perfect sense.
