Hi Mica,

Now it does, with some refactoring:

year1 = 1987
year2 = 1990

puts (year1 % 4 == 0 ? year1 + 4 : year1 + 1) while year1 <= year2

# => 1988 ...

Hope it helped.

Adriano

Subject: New to Ruby, Looking for Help With Basic Program

I am teaching myself Ruby and am trying to figure out why this program
is doing what it is doing:


puts 'Year 1?'
year1 = gets.chomp
puts 'Year 2?'
year2 = gets.chomp

while (year1.to_i <= year2.to_i)
if year1.to_i % 4 == 0
  leapyear = year1.to_i + 4
  puts leapyear
end
if year1.to_i % 4 != 0
  year1 = year1.to_i + 1
  puts year1
end
end



When year1 = 1987 and year2 = 1990, why is it printing out 1992? I am
expecting 1988.

Thanks in advance...
