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 a car.txt file

1. Fill in the 3 function prototypes according to their descriptions using 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);

Function definitions needed to be filled:

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;

int main(int argc, char *argv) //Main function { 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; }

/*

Functions that need to be filled

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

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 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.
