Define a Rectangle class that provides getLength and getWidth. Using the findMax routines in Figure 1.25(shown below), write a main that creates an array of Rectangle and finds the largest Rectangle first on the basis of area and then on the basis of perimeter.

1 // Generic findMax, with a function object, C++ style.

2 // Precondition: a.size( ) > 0.

3 template

4 const Object & findMax( const vector & arr, Comparator isLessThan )

5 {

6 int maxIndex = 0;

8 for(inti=1;i

9 if( isLessThan( arr[ maxIndex ], arr[ i ] ) )

10 maxIndex = i;

11

12 return arr[ maxIndex ];

13 }

15 // Generic findMax, using default ordering.
