How can I recognize the last iteration in a C++ while loop? -

-

How do I do that the last player's name is not , then it is: 

  Player Online: Jim, John, Tony

and not 

  Player Online: Jim, John, Tony,

My code is: 

  bool commands :: whoIsOnline (creature * c, const std :: string and cmd, const std :: string & ultimate ) {Player * player = dynamic_count & lt; Player * & gt; (C); If (player) {player-> SendTextMessage (MSG_STATUS_CONSOLE_BLUE, "player online:"); Autologist and lieutenant; Player & gt; :: Litterator IARR = Player :: listPlayer.list.begin (); Std :: String information; Int count = 0; While (IARR = Player :: listPlayer.list.end ()) {info + = (* iter) .second-> GetName () + "," ;; ++ ITER; ++ count; If (calculated% 10 == 0) {player-> SendTextMessage (MSG_STATUS_CONSOLE_BLUE, info.c_str ()); Info.clear (); }} If (Info.empty ()) player- & gt; Send Text Message (MSG_STATUS_CONSOLE_BLUE, info.c_str ()); } Back true; Instead of thinking it instead,  player + ","

it "," + player

, then you can do something like (psuedo-code): 

  But first name = true output = = "," output = = player name

if your language supports it (if it does C ++): if ONFSTNNAME: ONFERST_NAME = Incorrect Other: Output =): 

  If the player length & gt; 0: Output = Players [0] For players in players except [0]: Output + = "," + Player name Other: Output = ""

I like After all, I have to invent the language which actually works like this.

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends.
