Здравствуйте miheich, Вы писали:


Может там ошибка, может у тебя. А вот так попробуй (варнингов много будет)

int main(int argc, char* argv[]) 
{ 
    string from, to; 
    cin >> from >> to; 
    
    ifstream is(from.c_str()); 
    istream_iterator<string> ii(is); 
    istream_iterator<string> eos; 
    
    vector<string> b(1000); 
    sort(b.begin(),b.end()); 
    
    ofstream os(to.c_str()); 
    ostream_iterator<string> oo(os,"\n"); 
    unique_copy(b.begin(),b.end(),oo); 
    
    return !is.eof() && !os; 
}
