Three cars arrive at an intersection at about the same time as shown. Who has the right-of-way here?

You must always yield to any pedestrian in a crosswalk. Here, the pedestrian has the right-of-way. Therefore, Car C must yield to the pedestrian. Then Car B must yield to Car C, and finally, Car A must yield to Car B. [Pavement Markings, Chapter VI: Traffic Signs, Signals and Markings, Official Hawaii Driver's Manual]
