=====fill=====
Syntax:

<code>
    #include <algorithm>
    void fill( forward_iterator start, forward_iterator end, const TYPE& val );
</code>

The function fill() assigns val to all of the elements between start and end.

For example, the following code uses fill() to set all of the elements of a
vector of integers to -1:

<code>
   vector<int> v1;
   for( int i = 0; i < 10; i++ ) {
     v1.push_back( i );
   }

   cout << "Before, v1 is: ";
   for( vector<int>::size_type i = 0; i < v1.size(); i++ ) {
     cout << v1[i] << " ";
   }
   cout << endl;

   fill( v1.begin(), v1.end(), -1 );

   cout << "After, v1 is: ";
   for( vector<int>::size_type i = 0; i < v1.size(); i++ ) {
     cout << v1[i] << " ";
   }
   cout << endl;
</code>

When run, the above code displays:

<code terminal>
   Before, v1 is: 0 1 2 3 4 5 6 7 8 9
   After, v1 is: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1
</code>
