>Description:
#include <set>
#include <string>
#include <iostream>

using namespace::std;

int main( )
{
  set<string> mySet;
  set<string>::const_iterator iter;

  mySet.insert( "This" );
  mySet.insert( "is" );
  mySet.insert( "mySet" );
  iter = mySet.begin( );
  cout << *iter++ << " " << *iter++ << " " << *iter << endl;
  iter = mySet.begin( );
  cout << *iter++ << " " << *iter++ << " " << *iter++ << endl;
  iter = mySet.begin( );
  cout << *iter << " " << *(++iter) << " " << *(++iter) << endl;

  //WORKAROUND
  iter = mySet.begin( );
  cout << *iter << " ";
  iter++;
  cout << *iter << " ";
  iter++;
  cout << *iter << endl;
}

OUTPUT:
is This This
mySet is This
mySet mySet is
This is mySet
