How to populate an array using gets.chomp

Question

Here's what I have so far:

#Table of Contents using an array
title = "Table of Consents"

#Needs chapters inputted
chapters = Array.new

puts "Please input chapter names."

while gets.chomp != ""
  chapter = gets.chomp
  chapters.push chapter
  break if gets.chomp.empty?
end

#Needs corresponding page numbers inputted
pagenumbers = Array.new

puts "Please input corresponding page numbers."

while gets.chomp != ""
  pagenum = gets.chomp
  pagenumbers.push pagenum
  break if gets.chomp.empty?        
end

puts chapters
puts page numbers

I'm trying to get gets.chomp to continue adding to each array. When I push chapter or pagenum , I only get the last string/integer input. How do I get each input to populate the chapter or pagenum array?

The problem here is that every single time you write gets in your program, you are calling the gets method, which fetches a line of input from the user. You need to store that line somewhere so it can be used later. Try something like this:

chapters = []
while true
  input = gets.chomp
  break if input.empty?
  chapters << input
end
puts "Chapters: " + chapters.join(", ")
