C++/Deque/deque insert

Insert elements in vector to deque

<source lang="cpp">

1. include <iostream>
2. include <deque>
3. include <vector>

using namespace std; int main() {

  int data[5] = { 6, 8, 7, 6, 5 };
  vector<int> v(5, 6);            //5 element vector
  deque<int> d(data, data + 5);
  deque<int>::iterator p;
  cout << "\nDeque values" << endl;
  for (p = d.begin(); p != d.end(); ++p)
     cout << *p << "\t";      
  cout << endl;
  d.insert(d.begin(), v.begin(), v.end());
  for (p = d.begin(); p != d.end(); p++)
  cout << *p << "\t";   

}

Insert the remaining elements from the vector between the first and last deque elements

<source lang="cpp">

1. include <iostream>
2. include <deque>
3. include <vector>

using namespace std; const int SIZE = 100; double sum(const deque<double> &dq) {

  deque<double>::const_iterator p;
  double s = 0;
  for (p=dq.begin(); p != dq.end(); ++p)
     s += *p ;
  return s;

} int main() {

 vector<double> vec(SIZE, 0);   
 deque<double> deq;             
 int i;
 double sumTotal;
                                
 for(i = 0; i < SIZE; i++){
    vec[i] = i * 0.6; cout << vec[i] << endl;
 }
   deq.push_front(vec.front()); 
   deq.push_back(vec.back());  
   deq.insert(deq.begin()+1, vec.begin()+1, vec.end()-1);
   sumTotal = sum(deq);
   cout << "sum:" << sumTotal;

}
