## Chapter 8 ##

### Building and sorting an array

    puts "Enter your words"
    words = []
    while true
        word = gets.chomp
        if(word == '')
        	break
        end
        words.push(word)
    end
    words.sort.each do |w|
        puts w
    end


### Table of contents, revisited

    totalWidth = 60
    indexWidth = 3
    content = [["Getting Started", 1], ["Numbers", 9], ["Letters", 13]]


    puts "Table of Contents".center(totalWidth)
    puts
    chapterNumber = 1
    content.each do |chapter|
        section = "Chapter " + chapterNumber.to_s + ": " + chapter[0]
        index = "page " + chapter[1].to_s.rjust(indexWidth);
        if(section.length + index.length <= totalWidth)
        	puts section.ljust(section.length) + index.rjust(totalWidth - section.length)
        else
            puts section.ljust(totalWidth)
            puts index.rjust(totalWidth)
		end
        chapterNumber += 1
    end
