Program for age calculator in C

main()

{

   struct date d;

   int dat,mon,year,dob_day,dob_month,dob_year,age_day,age_month,age_year;

   getdate(&d);

   dat=d.da_day;           \\getting current date from the system

   mon=d.da_mon;        \\getting current month from the system

   year=d.da_year;         \\getting current year from the system

   printf("If you give invalid date it'll give wrong result:\n");

   printf("enter date of birth:\nday:(dd)");

   scanf("%d",&dob_day);

   printf("\nmonth (mm):");

   scanf("%d",&dob_month);

   printf("\nyear (yyyy)");

   scanf("%d",&dob_year);

    if(dat<dob_day)  
   {
      dat=dat+30;
      mon=mon-1;
     }
   if(mon<dob_month)
   {
      mon=mon+12;
      year=year-1;
     }
   age_day=dat-dob_day;                \\Calculating AGE
   age_month=mon-dob_month;
   age_year=year-dob_year;
   printf("your current age is:\n%d years %d months %d days",age_year,age_month,age_day);
   getch();
}
