It would be nice to create a box that is bigger than a given box. Write this method: public Box biggerBox( Box oldBox )
This is a public method that returns (evaluates to) a reference to a new Box. The new Box will be 25% larger in each dimension that the old box. The method will have to use a constructor inside of it to create the new box:
public Box biggerBox( Box oldBox )
{
return new Box( 1.25*oldBox. width(), )
}
Now write a method that returns a box that is 25% smaller in every dimension than a given box. As usual, write a testing program that exercises your class.
