Need help a with C++ programming problem. Will rate highly:

Purpose: To practice Posix-Threads trainLine.cpp Four trains of varying speeds run north-and-south on their own tracks. They visit different the two stations at either end: northTerminal after going north and southTerminal after going south. Because each train runs on its own track, they will not collide on the tracks. However, both station can only handle one train at a time. So if two trains are ever at the same station at the same time then there will be a CRASH More specifically, it is not the actual Station instance that should be locked, rather, it is the act of arrive ) -ing and leave ) -ing the Station that should be locked. Each train is implemented with its own thread. Please make the trains run both safely and on time. Note: Besides the C++ code in Station.h and trainiine.opp, this program requires you to give short answers for (b), (d) and (f) in the comments. Be sure these answers are clearly labeled! a. Making the Train Line multi-threaded Right now not much will happen. Therefore, please finish the following Finish main to make and join the Threads. I already have created NUM TRAINS for you. They are in trainArrayu. Please make NUM_NORTHERNLY_TRAINS threads (tidArray[O] to tidArray[NUM NORTHERNLY_TRAINS-1]) run 'initiallyNorthernly0'. Each thread should get a pointer to its own Train instance (trainArray[O] to trainArraylNUM_NORTHERNLY_TRAINS-1]. this is an array of POINTERS to trains, not trains themselves) Purpose: To practice Posix-Threads trainLine.cpp Four trains of varying speeds run north-and-south on their own tracks.
