Use subscript to access value from deque

Demo Code

#include <iostream>
#include <deque>
using namespace std;
void show(const char *msg, deque<int> q);
int main() {//from  www . j  av  a  2  s .c o  m
   //Declare a deque that has an initial capacity of 10.
   deque<int> dq(10);
   for(unsigned i=0; i < dq.size(); ++i)
      dq[i] = i*i;
   // Compute the average of the values. Again, notice
   // the use of the subscripting operator.
   int sum = 0;
   for(unsigned i=0; i < dq.size(); ++i)
      sum += dq[i];
   double avg = sum / dq.size();
   cout << "The average of the elements is " << avg << "\n\n";
   return 0;
}
// Display the contents of a deque<int>.
void show(const char *msg, deque<int> q) {
   cout << msg;
   for(unsigned i=0; i < q.size(); ++i)
      cout << q[i] << " ";
   cout << "\n";
}
