=====empty=====
Syntax:

<code>
    #include <vector>
    bool empty() const;
</code>

The empty() function returns true if the vector has no elements, false
otherwise.

For example, the following code uses empty() as the stopping condition on a
while loop to clear a vector and display its contents in reverse order:

<code>
    vector<int> v;
    for( int i = 0; i < 5; i++ ) 
    {
      v.push_back(i);
    }
    while( !v.empty() )
    {
      cout << v.back() << endl;
      v.pop_back();
    }
</code>
