car* readFromFile(FILE* fPtr)

Reads and parses lines from the input file, then calls insertInSortedOrder to add them to a linked list. Returns a pointer to the head of the linked list created in this way. fgets(), strtok(), and strcpy() will be useful here.

car* insertInSortedOrder(car* head, char* model, char* color, int year)

Uses createCar to make a new Car, then inserts that Car into the linked list beginning with head. The new Car should be inserted in ascending alphabetical order (A to Z) by model. Returns a pointer to the list's head. strcmp() will be useful here.

car* createCar(char* model, char* color, int year)

Creates a new Car that has the given model and year. This must be the only function in your program that uses malloc. If any other function uses malloc, you will lose 5 points.

int updateCar(car* head, char* targetModel, char* newModel)

Searches for a Car in the linked list beginning at head with the model targetModel. If found, the model for the Car should be replaced by newModel and 1 should be returned. If not found, -1 should be returned.

car* removeCar(car* head, char* targetModel)

Finds the Car with model targetModel and removes it from the linked list. Regardless of whether the Car is found in the list or not, this function always returns the head of the linked list. You may safely assume that at most one car has a model of targetModel, and end execution of the function after removing it.

char* verifyColor(FILE* cPtr, char* color)

Checks that a user-entered color matches one of the available colors from the colors.txt file. Returns the color string if the color is valid and the car can be added using insertInSortedOrder, else it loops until the user re-enters a valid color. If the color is invalid, this function prints out a list of valid colors. DO NOT hard-code the colors into your printf statement, i.e. your code should have a line that looks like printf(%s, , color);

void printCars(car* head)

Prints all the cars from the linked list. Output must be properly formatted (do not use tabs or spaces to fake the formatting!) or you will not receive points for this function.

int main(int argc, char** argv)

You should figure out how to call your functions in main to produce output matching the sample output. main will receive two command line arguments, which is the name of the input file and the name of the color file. Implement a simple error check in main that no car is newer than 2017.

NOTE: Only main, verifyColor, and printCars are allowed to use printf. No other function should produce any output. If they do, you will lose points for those functions.
