std::list::back(3)	       C++ Standard Libary	      std::list::back(3)

NAME
     std::list::back - std::list::back

Synopsis
	reference back();	      (1)
	const_reference back() const; (2)

	Returns a reference to the last element in the container.

	Calling back on an empty container causes undefined behavior.

Parameters
	(none)

Return value
	Reference to the last element.

Complexity
	Constant.

Notes
	For a non-empty container c, the expression c.back() is equivalent to
	*std::prev(c.end()).

Example
	The  following	code  uses  back  to  display  the  last  element  of  a
     std::list<char>:

     // Run this code

      #include <list>
      #include <iostream>

      int main()
      {
	  std::list<char> letters{'a', 'b', 'c', 'd', 'e', 'f'};

	  if (!letters.empty())
	      std::cout << "The  last  character  is  '"  <<  letters.back()  <<
     "'.\n";
      }

Output:
      The last character is 'f'.
