c++ - Compare vector iterator with integer -

string str = cpy[i].second; itr = find(v.begin(), v.end(), str); auto pos = distance(v.begin(), itr); //auto pos = itr - v.begin(); if(pos >= v.size() / 2)     cout << str << " "; else     cout << "-" << " "; 

here cpy vector of int , string pair, i.e, vector<pair<int,string>>cpy. above part gives error "pos not name type.".
how resolve it?

you can change type of pos int. think compiler doesn't support auto.
