Question

Define a structure type auto_t to represent an automobile. Include components for the make and model ( strings), the odometer reading, the manufacture, and purchase dates (use another user-defined type called data_t), and the gas tank ( use a user-defined hype tank_t with componetns for tank capacity and current fuel level, giving both ingallons). Write I/O functions scan_data, scan_tank, scan_auto, print_date, print_tank, and print_auto, and also write a driver function therepeatedly fills and displays an auto structure variable until EOF is encountered in the input file.

**C not C++

Data set to try:

Mercury Sable 99842 1 18 2001 5 30 1991 16 12.5

#include <stdio.h>
#include <string.h>
#define BUFSIZE 1000
struct auto_t scan_auto(char *);
struct date_t {
   char day[2];
   char month[2];
   char year[4];
};

struct tank_t {
   char tankCapacity[10];
   char currentFuelLevel[10];

struct auto_t {
   char make[50];
   char model[50];
   char odometerReading[10];
   struct date_t manufactureDate;
   struct date_t purchaseDate;
   struct tank_t gasTank;
};

int main(int argc, char *argv[]) {
/* the first command-line parameter is in argv[1]
(arg[0] is the name of the program) */
FILE *fp = fopen(argv[1], "r"); /* "r" = open for reading */

char buff[BUFSIZE]; /* a buffer to hold what you read in */
struct auto_t newAuto;

/* read in one line, up to BUFSIZE-1 in length */
while(fgets(buff, BUFSIZE - 1, fp) != NULL)
{
/* buff has one line of the file, do with it what you will... */
   newAuto = scan_auto(buff);
   printf("%s ", newAuto.make);
  
}
fclose(fp); /* close the file */
}

struct auto_t scan_auto(char *line) {
   int spacesCount = 0;
   int i, endOfMake, endOfModel, endOfOdometer;
   for (i = 0; i < sizeof(line); i++) {
       if (line[i] == ' ') {
           spacesCount++;
           if (spacesCount == 1) {

           }
       }

   }
   struct auto_t newAuto;
   int count = 0;
   for (i = 0; i < endOfMake; i++) {
       newAuto.make[count++] = line[i];
