Exercise: Rectangle Area

Create a program that:

Asks a user for the x and y coordinates of two points. Use integers for the coordinates.
Calculates the area of the rectangle defined by these two points.

Two rectangles with their lower left and upper right corners shown, inside a Cartesian coordinate system.

Your program output should look like this (user input in green):

Point 1:
  x coordinate: 2
  y coordinate: 1
Point 2:
  x coordinate: 4
  y coordinate: 4

Rectangle width: 2, height: 3, area: 6

Width and height are calculated as the absolute difference of the x and y coordinates, respectively. This entails that the order of the points does not matter:

Point 1:
  x coordinate: 4
  y coordinate: 4
Point 2:
  x coordinate: 2
  y coordinate: 1

Rectangle width: 2, height: 3, area: 6

Coordinates might be negative:

Point 1:
  x coordinate: 1
  y coordinate: 1
Point 2:
  x coordinate: -4
  y coordinate: -2

Rectangle width: 5, height: 3, area: 15
