using namespace std; 

vector<double> makevector(int size){

  vector<double> result;
  for (int i=1; i<=size; i++) { 
    result.push_back(double(i)); 
  } 
  return result; 
} 

void print(const vector<double>& l)

  cout << "Size of vector is: " << l.size() << endl; 

  vector<double>::const_iterator i; 

  for (i=l.begin(); i!=l.end(); i++)

    cout << (*i) << " "; 
  } 

  cout << endl; 
} 

int main() 
{ 
  vector<double> vector1=makevector(5); 
  vector<double>::iterator bi; 

  vector<double>::reverse_iterator ri; 

  ri=vector1.rbegin();          // Set iterator 
  while (ri!=vector1.rend()) cout << (*ri++) << " "; 
  cout << endl << endl; 

  // Change element with const iterator 
  cout << "Change first element with const iterator" << endl; 
  vector<double>::const_iterator ci;
