In C Language

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, and one struct for list. The program gets input from the command line with car.txt file

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

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:

Functions needed to initialize the linked list:

Starter Code to Copy:

typedef struct car { char type[15]; // sports car, truck, convertible etc char make[20]; char model[30]; char engine[15]; // V6, V8, V4 etc int hp; // horse power char color[25]; int length; // length of car in feet double base_price; double total_price; accessories_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], "r");

//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 0; }

list_t *newList() //Creating list { list_t *point = (list_t *)malloc(sizeof(list_t));

point->head = NULL; point->tail = NULL; point->size = 0;

return point; }
