I realized this: boost::counting_iterator<int> it(0); boost::counting_iterator<int> end(lsv.length()); while (it < end) cout << boost::bind(&LegacyStringVector::operator[], lsv, _1)(*it++) << " "; cout << "\n"; and it works. However, I wish to do the same but using std::copy or std::for_each instead. I tried the following but none is able to compile: copy(boost::counting_iterator<int>(0), boost::counting_iterator<int>(lsv.size()), boost::bind(ostream_iterator<string>(cout, " "), &vector<string>::operator[], lsv, _1)); copy(boost::counting_iterator<int>(0), boost::counting_iterator<int>(lsv.size()), boost::bind(ostream_iterator<string>(cout, " "), boost::bind(&vector<string>::operator[], lsv, _1))); copy(boost::counting_iterator<int>(0), boost::counting_iterator<int>(lsv.size()), boost::bind(ostream_iterator<string>(cout, " "), boost::bind(&vector<string>::operator[], lsv), _1)); I must be close to the solution but error messages do not help guiding me in the right direction. Anyone has any suggestion?
