Function Definitions needed to be filled ( list_t *newList() has already been completed) :

1. Given the current starter code, fill in the function definitions stated above (the function list_t *newList() has already been completed).

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); 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.

Returns a pointer to the new list. 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 new car node from the input file pointer passed in. Returns a pointer to the car that was just created. 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); 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.
