       std::deque::pop_back - std::deque::pop_back

Synopsis
	  void pop_back();

	  Removes the last element of the container.

	  Calling  pop_back  on	an empty container results in undefined	behav-
       ior.

	  Iterators and	references to the erased element are  invalidated.  It
       is
	  unspecified  whether the past-the-end	iterator is invalidated. Other
       (until C++11)
	  references and iterators are not affected.
	  Iterators and	references to the erased element are invalidated. The
	  past-the-end iterator	is  also  invalidated.	Other  references  and
       (since C++11)
	  iterators are	not affected.

	  (none)

       // Run this code

	#include <deque>
	#include <iostream>

	template<typename T>
	void print(T const & xs)
	{
	    std::cout << "[ ";
	    for(auto const & x : xs) {
		std::cout << x << ' ';
	    }
	    std::cout << "]\n";
	}

	int main()
	{
	    std::deque<int> numbers;

	    print(numbers);

	    numbers.push_back(5);
	    numbers.push_back(3);
	    numbers.push_back(4);

	    print(numbers);

	    numbers.pop_back();

	    print(numbers);
	}

Output:
	[ ]
	[ 5 3 4	]
	[ 5 3 ]
