Write a program that simulates the control software for a people mover" system, a set of driverless trains that move in two concentric circular tracks. A set of switches allows trains to switch tracks. In your program, the outer and inner tracks should each be divided into ten segments. Each track segment can contain a train that moves either clockwise or counterclockwise. A train moves to an adjacent segment in its track or, if that segment is occupied, to the adjacent segment in the other track. Define a Segment structure. Each segment has a pointer to the next and previous segments in its track, a pointer to the next and previous segments in the other track, and a train indicator that is 0 (empty), TexPhoto/iStockphoto +1 (train moving clockwise), or -1 (train moving counterclockwise). Populate the system with four trains at random segments, two in each direction. Display the tracks and trains in each step, like this: 1 x x x x x | | 11 11 | - >. or . or
