Printing a Range to a Stream

Demo Code

#include <iostream>
#include <string>
#include <algorithm>
#include <iterator>
#include <vector>

using namespace std;
template<typename C>
void printContainer(const C& c, char delim = ',', ostream& out = cout) {
   printRange(c.begin(), c.end(), delim, out);
}

template<typename Fwd>
void printRange(Fwd first, Fwd last, char delim = ',', ostream& out = cout) {
   out << "{";
   while (first != last) {
      out << *first;//w  ww  . j a v  a  2 s .  c o m
      if (++first != last)
         out << delim << ' ';
   }
   out << "}" << endl;
}

int main() {

   cout << "Enter a series of strings: ";
   istream_iterator<string> start(cin);
   istream_iterator<string> end;
   vector<string> v(start, end);

   copy(v.begin(), v.end(), ostream_iterator<string>(cout, ", "));

   printContainer(v);
   printRange(v.begin(), v.end(), ';', cout);
}
