/* C++ Primer - 4/e

 * STATEMENT
 *       Write a program to process a list of strings. Look for a 
   particular value and if found remove it. Repeat the program usinig a
 * deque. *

 */
 
 
#include <iostream>
#include <list>
#include <deque>
#include <algorithm>
#include <iterator>

int main()
{
  std::cout << "Enter some words: ";
  std::list<std::string> slist;
  std::copy( std::istream_iterator<std::string>( std::cin ),
	     std::istream_iterator<std::string>(),
	     std::back_inserter( slist ) );

std::cin.clear();
  std::cout << "Enter the word you want to remove: ";
  std::string rem_word;
  std::cin >> rem_word;
  std::remove( slist.begin(), slist.end(), rem_word);

std::copy( slist.begin(), slist.end(), 
	     std::ostream_iterator<std::string>( std::cout, " " ) );
  std::cout << std::endl;

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.
