   C++ text to int  question
  Hi every one,I’ve just started programming in c++ and was wondering how would you convert a in to string an back ? I’m programming without the standard libraries.any ideas.Roy   
  If you're posting in "For Beginners" trying to program without the standard library is not a particularly sane methodology.In any case, you can either use  boost::lexical_cast or a std::stringstream.std::stringstream sstr;sstr << my_int;std::string str1 = sstr.str();std::string str2 = boost::lexical_cast<std::string>(my_int);;Quote:I’m programming without the standard libraries.Is there any particular reason for doing so? I mean, even input and output are going to cause trouble with such a mindset.   ;  Well this is every thing i'm using#include <windows.h>#include <windowsx.h>#include <d3d9.h>#include <d3dx9.h>#include <dinput.h>its off a tutorial from.http://www.directxtutorial.comand i dont wat to use .net   ;Quote:Original post by precious royWell this is every thing i'm using#include <windows.h>#include <windowsx.h>#include <d3d9.h>#include <d3dx9.h>#include <dinput.h>its off a tutorial from.http://www.directxtutorial.comYou know that you're allowed to include more header files than what a tutorial says, right?

If you search for the header name, you should be able to find a list of classes and functions it exposes.   ;Here and here. These are two sites that you will find frequently at the top of a Google search for a SC++L feature.   ;  thank you veryy mutch.. you have opend new dors for me :} but one more question how would i convert string to LPCWSTRMost web sites say that this should workint i = 1;std::stringstream sstr;sstr<<i;std::string test = sstr.str();    d3dfnt->DrawText(NULL, test.c_str(), -1, &rct, 0, TextColor );but it gives a can not convert error.
