  Hello all,
  I try to store number 01 in integer i like this : int i = 01; cout
  << i ;
  You do not understand what "int" means. More generally, you do not
  understand how numbers are represented in a computer. There is no such
  thing as an "int with value 01". There is only value 1. "0" is just
  padding that you can add when you turn your "int" into a string of
  characters (which happens for you when you "insert" a number into a
  stream).
  It simply prints 1. What I want is to print 01.
  Is it possible ?
  Try
  #include <iomanip>
  cout << setw(2) << setfill('0') << i;
  Goran.
  Thanks for your answers.
  I do understand what integer means and how computer stores it.
  I try to be more specific. I dont want to pad 0 to int i in cout. So
  iomanip is useless for me.
  What I want is when I convert integer 1 to string, the value of string
  should become 01 (I want to pad 0 to string after converting it from
  int).
  Any ideas ?
  #include <iomanip>
  #include <iostream>
  #include <sstream>
  #include <string>
  int main()
  {
  int i = 1;
  std::ostringstream oss;
  oss << std::setw(2) << std::setfill('0') << i;
  std::string s = oss.str();
  std::cout << s << '\n';
  return 0;
  }
  Cheers,
  Stu
