Re: something like Perl's join function

Carlos, Seungbeom, Abdalla, Carl, Joshua and others,

Thanks for your replies. Seungbeom, your ostream_join_iterator is
really cool. I wish it got to the standard some day, but I can only
wish. :) Finally I have this minimalistic << operator for a vector
(shown below) and now it's sufficient for me.

Best,
Irek

*******************************************

#include <iostream>
#include <vector>

using namespace std;

template <typename T>
ostream &operator << (ostream &os, const vector<T> &v)
{
   typename vector<T>::const_iterator i = v.begin();

   while(i != v.end())
     {
       os << *i;
       if (++i != v.end())
         os << ", ";
     }

   return os;
}

int main()
{
   vector<int> a;

   cout << a << endl;
   a.push_back(1);
   cout << a << endl;
   a.push_back(2);
   cout << a << endl;
   a.push_back(3);
   cout << a << endl;

   return 0;
}
