How to run this and have the following output: [Create a test file so I get the same as the picture output, and how to compile it]

Q:

A runway of airplanes at an airport. The runway can have only one plane on it at one time. There are two types of planes: planes taking off and planes landing. For each plane that takes off, one must land. As well, planes must take off in the order in which they enter the takeoff queue. Planes must land in the order in which they enter the landing queue. Use semaphores to design a synchronization scheme with some properties.

Code:

//Include the needed header files #include #include #include #include

//Structure typedef struct { //Variables int planeID; pthread_t planeTD; } planes_thread;

//Semaphores sem_t runwaySemaphore; sem_t queueSemaphore; sem_t queueMutex;

//Method planeLand() static void planeLand(int planeID) { //Display printf("[PLANE_TO_LAND]: Airplane %d asks permission to land ", planeID); //Semaphore wait sem_wait(&runwaySemaphore); //Display printf("[PLANE_LANDED]: ===> Airplane %d has landed ", planeID); }

//Method planeQueue() static void planeQueue(int planeID) { //Variable int sValue; //Display printf("[PLANE_LANDED]: Airplane %d asks permission to go to gates ", planeID); //Semaphore wait sem_wait(&queueSemaphore); //Semaphore get value sem_getvalue(&queueSemaphore, &sValue); //Check condition if (sValue != 0) { //Semaphore wait sem_wait(&queueMutex); } //Otherwise else { //Semaphore sem_post(&queueMutex); //Semaphore sem_post(&queueMutex); } //Semaphore sem_post(&runwaySemaphore); //Display printf("[PLANE_TO_GATE]: ===> Airplane %d did proceed to gate: %d ", planeID, 3 - sValue); //Semaphore sem_post(&queueSemaphore); }

//Method planeFunction() static void* planeFunction(void* args) { //New planes_thread* p = (planes_thread*)args; //Function call planeLand(p->planeID); //Function call planeQueue(p->planeID); //Return return NULL; }

//Method usage static void usage(char** argv) { //Display fprintf(stderr, "Usage: %s number_of_planes number_of_runways ", argv[0]); }

//Driver int main(int argc, char* argv[]) { //Initialize needed variables int nVal = 0, mVal = 0, index, tStatus; planes_thread* planes; //Check condition if (argc != 3) { //Function call usage(argv); //Exit exit(EXIT_FAILURE); } //Assign nVal = atoi(argv[1]); //Assign mVal = atoi(argv[2]); //Check condition if (nVal
