This program's purpose is to create a singly linked-list for cars to keep track of inventory. To do this, I'm using structures, one struct car, one struct car_accessories (not listed), and one struct for list.

1. Fill in the function prototypes given above main() in the starter code according to the descriptions posted below the starter code.

Function Prototypes to fill:

void listInitializer (list_t *list, FILE *inFile); void initializeFromFile (list_t *list, FILE *inFile); car_s *newCar (FILE *inFile);

STARTER CODE:

FUNCTION DEFINITIONS TO FILL:

typedef struct car { char make[20]; char model[30]; char color [25); char trim[15]; double basePrice; double finalPrice; char engine[15]; int torque; int horsepower; int carLength; carAccessories_t extras; struct car *next; } car_s; typedef struct list { car_s *head; car_s *tail; int size; } list_t; void listInitializer (list_t *list, FILE *inFile); void initializeFromFile (list_t *list, FILE *inFile); car_s *newCar (FILE *inFile); 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 int main(int argc, char *argv) { list_t *list()=newList(); FILE* inFile = NULL; //Opening .txt file inFile = fopen(argv[1], ""); //Error message if null or does not exist, return -1 if (inFile == NULL) { printf("Could not open file. "); return -1; // -1 indicates error } initializeFromFile (list_t *list, FILE *inFile); return; } list_t *newList() { list_t *point = (list_t *)malloc(sizeof(list_t)); point->head = NULL; point->tail = NULL; point->size = 0; return point; } void listInitializer (list_t *list, FILE *inFile); - This function is called from initializeFromFile(): This funtion calls newcar () to create and initialize a new car from the file which it then adds to the end of the list. This function also increments the list size for each car added. void initializeFromFile (list_t *list, FILE *inFile); -Calls the listInitializer() function, which sends the input file pointer (the file specified at command-line and opened in int main(int argc, char *argv) ) -Calls listInitializer () in a loop until the end of the file car s *newCar (FILE *inFile); Called by the listInitializer () function. Creates and initializes a car node from the input file pointer passed in. Returns a pointer to the car that was just created. new typedef struct car { char make[20]; char model[30]; char color [25); char trim[15]; double basePrice; double finalPrice; char engine[15]; int torque; int horsepower; int carLength; carAccessories_t extras; struct car *next; } car_s; typedef struct list { car_s *head; car_s *tail; int size; } list_t; void listInitializer (list_t *list, FILE *inFile); void initializeFromFile (list_t *list, FILE *inFile); car_s *newCar (FILE *inFile); 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 int main(int argc, char *argv) { list_t *list()=newList(); FILE* inFile = NULL; //Opening .txt file inFile = fopen(argv[1], ""); //Error message if null or does not exist, return -1 if (inFile == NULL) { printf("Could not open file.
