# 4.37 (Turtle: point in a rectangle?) Write a program that prompts the user to enter a
# point (x, y) and checks whether the point is within the rectangle centered at (0,
# 0) with width 100 and height 50. Display the point, the rectangle, and a message
# indicating whether the point is inside the rectangle in the window, as shown in
# Figure 4.14.
