using namespace std;

int main()
{
  const char *a[3]={"field1","field2","field3"};

  // If you want to create a brand new vector
  vector v(a, a+3);
  std::copy(v.begin(), v.end(), ostream_iterator(cout, "\n"));

  vector v2;
  // Or, if you already have an existing vector
  vector(a,a+3).swap(v2);
  std::copy(v2.begin(), v2.end(), ostream_iterator(cout, "\n"));

  vector v3;
  v3.push_back("field0");
  // Or, if you want to add strings to an existing vector
  v3.insert(v3.end(), a, a+3);
  std::copy(v3.begin(), v3.end(), ostream_iterator(cout, "\n"));
