[noob][c++] set:: accessors & mutators

#include <iostream>
#include <set>

using namespace std;

int main()
{
      set<int, greater<int> > s;
      set<int, greater<int> >::iterator i;

      s.insert(4);
      s.insert(1);
      s.insert(2);
      s.insert(4);
      s.insert(3);
      s.insert(6);
         

       cout << "The set contains the elements: " << endl;
       for (i=s.begin();  i !=s.end();  i++)
       {
       cout << *i  << endl;
       }
}

       cout << "The set contains the elements: " << endl;
       for (i=s.begin();  i !=s.end();  i++)
       {
       cout << *i  << endl;
       }



while I understand that this is a for loop, I don't get how the individual parts work.


1)  how do I cout an element of the set?

     i know it's not

     cout << s << endl;


2)  more to follow.
