Hi, Attached are two programs that represent one-way and two-way traffic on a road. I can get the programs to produce reasonable results that match our intuitive ideas of roads. However, I have 2 question about the programs:
1)I cannot get the result suggested by the author that t1 should give true in prog1 and false in prog2.
Only took a short look, but that'd probably be because it's wrong, t1 should give True for both. You have a road r from a to b and a car c at a. Then after you move the car along the road, it will be located at b, regardless of whether it's a one- way road or traffic may flow in both directions.
