converting address to string

converting address to string

• F. Gsell

  Given:

  int i(99), *pi=&i;

  You can output the address directly using:

  std::cout << i << ' ' << pi << '\n';

  Or you can convert to a string using ostringstream as in:

  std::ostringstream ss;
  ss << pi;
  std::cout << ss.str() << '\n';

  Another way to convert to a string is _ultoa or _ultoa_s, but this does not provide leading zeros:

  char Buffer[16];
  _ultoa(reinterpret_cast(pi), Buffer, 16);
  std::cout << Buffer << '\n';

  thank you for taking the time to anwer my question, but when I try to make a ostringstream it gives me the following error:

  error C2079: 'sc' uses undefined class 'std::basic_ostringstream<_Elem,_Traits,_Alloc>'

  with

  [

  _Elem=char,

  _Traits=std::char_traits<char>,

  _Alloc=std::allocator<char>

  ]

  Just as a side note you can have a look at some (not so intuitive, but handy) code of mine at http://einaros.blogspot.com/2006/11/put-hex-on-that-dump.html.

  Thank you for your help, I have another related question if it's not to much bother:

  is there way I can convert the address of what a managed handle points to to a string

  
  

• TeleRiddler

  I already included the following:

  #include "stdafx.h"

  #include <iostream>

  #include <fstream>

  What am I missing

  Just as for all the STL classes, you need to do the relevant #include.
