Description:
Include the following definitions at the top of your program:

#define MAX_STRING_LEN 20

typedef struct {
int year;
char* make;
char* model;
int miles;
} Car;

void fill_garage(Car** garage, char* cars, int* size);

Parameter: garage – A pointer to the pointer, which points to the head of an array of cars
Parameter: cars – The name of the input file
Parameter: size – A pointer to the variable where the size of the array will be stored

This function will dynamically create an array to hold the cars and read the contents of
the input file into it. This is the only function which is allowed to use malloc in your
assignment.

int equals (Car* car, int year, char* make, char* model);

Parameter: car – A pointer to a car struct
Parameter: year – A valid year
Parameter: make - A cars make
Parameter: model – A cars model
Return: 1 if the car has the given year, make, and model; 0 otherwise
This function will determine if the provided car has the specified year, make, and model

void drive_cars(Car* garage, int* num_cars, char* driving_records);

Parameter: garage – An array of cars
Parameter: num_cars – The length of the garage array
Parameter: driving_records – The name of a file containing driving records
This function will read from the file specified by the driving_records parameter and on
each line read in a year, make, model, and number of miles driven. It will then add the
number of miles to the specified car. If the car does not exist, no action should be taken.

void store_car_statisitcs(Car* garage, int num_cars, char* outFile);

Parameter: garage– An array of cars
Parameter: num_cars – The length of the garage array
Parameter: outFile – The name of the file to store the car information
Write the car statistics to the output file. See example output below.

void empty_garage(Car* garage, int num_cars);

Parameter: garage – An array of cars
Parameter: num_cars – The length of the garage array
Frees all malloced memory

int main(int argc, char* argv[]);

Main should take in the names of the three files as command line arguments and then act
as a driver to call the other functions. It should error check for the correct number of
command line arguments.
