Answer 1

Please tell in which programming language do you need it. I will post the same in the comment.

Answer 2

import java.io.*;

 

class GFG {

   static void findAge(int current_date, int current_month,

                   int current_year, int birth_date,

                   int birth_month, int birth_year)

   {

       int month[] = { 31, 28, 31, 30, 31, 30, 31,

                            31, 30, 31, 30, 31 };

 

       // if birth date is greater then current

       // birth_month, then donot count this month

       // and add 30 to the date so as to subtract

       // the date and get the remaining days

       if (birth_date > current_date) {

           current_month = current_month - 1;

           current_date = current_date + month[birth_month - 1];

       }

 

       // if birth month exceeds current month,

       // then do not count this year and add

       // 12 to the month so that we can subtract

       // and find out the difference

       if (birth_month > current_month) {

           current_year = current_year - 1;

           current_month = current_month + 12;

       }

 

       // calculate date, month, year

       int calculated_date = current_date - birth_date;

       int calculated_month = current_month - birth_month;

       int calculated_year = current_year - birth_year;

 

       // print the present age

       System.out.println("Present Age");

       System.out.println("Years: " + calculated_year +

             " Months: " + calculated_month + " Days: " +

             calculated_date);

   }

   public static void main(String[] args)

   {

       // present date

       int current_date = 7;

       int current_month = 12;

       int current_year = 2017;

 

       // birth dd// mm// yyyy

       int birth_date = 16;

       int birth_month = 12;

       int birth_year = 2009;

 

       // function call to print age

       findAge(current_date, current_month, current_year,

             birth_date, birth_month, birth_year);

   }

}
