C programing, can someone help please

[Snoop]

Im trying to help out a friend in a beginning C class. The problem is stumping myself and another somewhat C literate friend of mine(we both have taken some advanced C courses). Heres the problem.

You have to make two cities, one tampa, one orlando in boxes on the screen. You then have to make a car(arrow) travel from left to right btw the cities, turn around (arrow change?), then return to the beginning city.

I cannot figure this out, I have trid doing a couple different array setups, but i CANNOT seem to grasp how to get the arrow to move from left to right, right to left in between the two cities.(cannot just use tab, he specifically stated she needed to use arrays). Now, the only help i have thus far been able to find is this (program below): but its not helping me out that much since its moving the rocket upwards instead of left to right, right to left.
IF anyone has any ideas on how to go about doing this I am open for suggestions Thanks
