I need to ask the user for their birth year, and then display every year from the birth year to 2017 with the age for each year.

I started with this:

puts "when are you born (year) ?"
birth_year = gets.to_i
birth_year.upto(2017)birth_year

I miss the part to display the age. I tried some stuff like:

puts birth_year.upto(2017) - birth_year

but it did not work.

  Your block variable name is semantically incorrect. Rename it and then you'll easily see the correct calculation.

  "Did not work" is not a useful diagnostic. Error messages, especially the exact text of those, is a lot better.

You can use a different form of block like this:

puts "when are you born (year) ?"
birth_year = gets.to_i 
birth_year.upto(2017) do |iterating_year|
 puts "Year: #iterating_year"
 puts "Age: #iterating_year - birth_year "
end

Or if you want it all in the same line try this - but it's less readable:

birth_year.upto(2017) iterating_year

Naming block variables

• Recommendation: Do not use the same variable name in your block as you have outside the block - that's just confusing. In this particular case, with the code as you have written it, the birth_year you have defined outside the block will have fallen out of scope, and the block parameter will take on the iterating years value: 2001, 2002, 2003 etc.

String Interpolation

This is when join strings together. One method you could use is to write some ruby code inside a string - you need a hash tag and opening and closing curly brackets to make it work. See this link for more info or google "ruby string interpoloation".

  Ruby will actually warn about "variable shadowing" which is using the same name twice in different, overlapping scopes, if the -w flag is enabled. It's a good idea to avoid it not only because it's confusing, but because it can lead to unexpected results.
