#include <iostream>

int main()
{
  std::cout << "Enter some words: ";
  std::list<std::string> slist;

         std::istream_iterator<std::string>(),

  return 0;
}

============= OUTPUT =============
/home/arnuld/programming/c++ $ g++ -ansi -pedantic -Wall -Wextra
ex_09.27.cpp

/home/arnuld/programming/c++ $ ./a.out
Enter some words: ab cd ef gh

Enter the word you want to remove: ef

ab cd gh gh
/home/arnuld/programming/c++ $

Did you notice ?

The "ef" was NOT removed but replcaed with "gh" . Why so ? It is
std::remove algorithm and should remove, not replace.
