/*
February 29 is a date that usually occurs every four years, and is called leap day. 
This day is added to the calendar in leap years as a corrective measure, 
because the Earth does not orbit around the sun in precisely 365 days.
Write a program which uses a loop to print the next 20 Leap Years starting with 2016.

Choose any loop you wish.

NOTE: Do not do the calculations yourself. Start the year at 2016, loop 20 times adding 4 each time.
