  print 'year of birth:'
  byear = raw_input()
  print 'current year:'
  curyear = raw_input()
  
  
  if curyear < byear:
          curyear = (int) ('2' + curyear)
  else:
          curyear = (int) ('1' + curyear)
  
  byear = (int) ('1' + byear)
  
  age = curyear - byear
  print 'your age: ' + str(age)

  if curyear < byear:
      curyear = 200 + int(curyear)
  else:
      curyear = 100 + int(curyear) 
  byear = 100 + int(byear)

  Here is my solution in Java:

  public class Main {
      public static void main(String[] args) {
          int age;
          Scanner s = new Scanner(System.in);
          System.out.println("When were you born?");
          int birth = s.nextInt();
          System.out.println("What is the current year?");
          int current = s.nextInt();
          s.close();
          if(birth < current){
              //born post 2k
              age = current - birth;
          }else{
              int pre2k = 100 - birth;
              int post2k = current;
              age = pre2k + post2k;
          }
          System.out.println("You are " + age + " years old.");
      }
  }

  Oh and obviously it should have:

  import java.util.Scanner;
  

  at the top :)

  c# ``` var birth = 0; var current = 0;

      Console.WriteLine("2 digit birth year?");
      while( !int.TryParse(Console.ReadLine(), out birth) || Math.Floor(Math.Log10(birth) + 1) != 2)
          continue;
  
      Console.WriteLine("2 digit current year?");
      while(!int.TryParse(Console.ReadLine(), out current) || Math.Floor(Math.Log10(current) + 1) != 2)
          continue;
  
      Console.WriteLine(current - birth < 0 ? current-birth+100 : current - birth);

  #include <iostream>
  using namespace std;
  int main (void){
      int born, current;
      cout<<"Year of birth: ";
      cin>>born;
      cout<<"Current year: ";
      cin>>current;
      cout<<"Your age: "<<current-born+100;
      getchar();
      getchar();
  }

  Easy-peasy lemon squeezy in LISP!

  (defun find-age-helper (birth-year this-year)
    (+ (- 100 birth-year) this-year))
  
  (defun find-age ()
    (let ((birth-year 0)
      (current-year 0))
      (format t "Year of Birth: ")
      (setf birth-year (read))
      (format t "Current year: ")
      (setf current-year (read))
      (format t "Your age: ~D" (find-age-helper birth-year current-year))))

  As far as I can tell this is probably the most efficient way to do this (there might be little tweaks, but I mean the general idea). Wrote this up in C++.

  #include <iostream>
  
  using namespace std;
  int main()
  {
      int birth;
      cout << "Year of birth: ";
      cin >> birth;
      int curr;
      cout << "Current Year: ";
      cin >> curr;
      int res = curr - birth;
      cout << "Your age: " << res+(res < 0?100:0)<<endl;
      return 0;
  }

  import java.util.Scanner;
  public class Y2K
  {
      public static void main(String[] args)
      {
          Scanner in = new Scanner(System.in);
          int yearBorn = 0;
          int currentYear = 0;
  
          System.out.print("Year born: ");
          yearBorn = in.nextInt();
          System.out.print("Current year: ");
          currentYear = in.nextInt();
          if(yearBorn <= currentYear)
              yearBorn += 100;
          System.out.println("Current age: " + (((currentYear+100)-yearBorn)));
      }
  }

  Some Python

  def agefinder(birth,current):
      age = 0
      age = (100 - int(birth)) + int(current)
      return(age)
  
  yourage = agefinder(input('Last 2 digits of your birth year:'),input('Last 2 digits of current year:'))
  
  print('You are',yourage,'Years old.')

  And a one liner for good measure

  print('You are',(100-(int(input('Birth year:')))) + (int(input('Current year:'))))
