Question

(Geometry: two rectangles) Write a program that prompts the user to enter the
center coordinates, width, and height of two rectangles from the command line.
The program displays the rectangles and a text indicating whether the two are
overlapping, whether one is contained in the other, or whether they dont overlap,
as shown in Figure 14.50. See Programming Exercise 10.13 for checking the
relationship between two rectangles.
