deque::pop_back

public member function
void pop_back ( );

Delete last element

Removes the last element in the deque container, effectively reducing the container size by one.

This calls the removed element's destructor.

Parameters

none

Return value

none

// deque::pop_back
#include <iostream>
#include <deque>
using namespace std;
int main ()
{
  deque<int> mydeque;
  int sum (0);
  mydeque.push_back (10);
  mydeque.push_back (20);
  mydeque.push_back (30);
  while (!mydeque.empty())
  {
    sum+=mydeque.back();
    mydeque.pop_back();
  }
  cout << "The elements of mydeque summed " << sum << endl;
  return 0;
}

In this example, the elements are popped out from the end of the deque after they are added up in the sum. Output:
The elements of mydeque summed 60

Complexity

Constant.
