## back

Syntax:

        #include <list>
        TYPE& back();
        const TYPE& back() const;

The back() function returns a reference to the last element in the list.

For example:

       list<int> l;
       for( int i = 0; i < 5; i++ ) {
         l.push_back(i);
       }
       cout << "The first element is " << l.front()
            << " and the last element is " << l.back() << endl;

This code produces the following output:

       The first element is 0 and the last element is 4

The back() function runs in constant time.
