Listing 3 A program that shows how to use the Date class

// tdate.cpp: Test the Date class

#include <stdio.h>
#include <stdlib.h>
#include "date.h"

main()
{
   Date d1, d2, *result;
   int nargs;
   
   // Read in two dates - assume 1st precedes 2nd
   fputs("Enter a date, MM/DD/YY> ",stderr);
   nargs = scanf("%d/%d/%d%*c", &d1.month,
     &d1.day, &d1.year);
   if (nargs != 3)
      return EXIT_FAILURE;
      
   fputs("Enter a later date, MM/DD/YY> ",stderr);
   nargs = scanf("%d/%d/%d%*c", &d2.month,
     &d2.day, &d2.year);
   if (nargs != 3)
      return EXIT_FAILURE;
   
   // Compute interval in years, months, and days
   result = d1.interval(d2);
   printf("years: %d, months: %d, days: %d\n",
      result->year, result->month, result->day);
   return EXIT_SUCCESS;
}

/* Sample Execution:
Enter a date, MM/DD/YY> 10/1/51
Enter a later date, MM/DD/YY> 11/14/92
years: 41, months: 1, days: 13
