NAME
     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 behavior.

	Iterators  and	references  to	the  erased element are invalidated. The
     end() iterator
	is also invalidated. Other references and iterators are not affected.

Parameters
	(none)

Return value
	(none)

Complexity
	Constant.

Exceptions
	Throws nothing.

Example
     // 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 ]
