arraywords.rb

## Write a program that asks for as many word as you want (one word per line)
## until you press enter on an empty line, and then repeats all the words back in alphabetical 
## order

## Where to being with this one? I got to the words = [] portion but wasn't 
## sure how to get multiple words, entered separately a.) into the array and b.) on a loop. 
## After trying a variety of ways, I broke down and did some googling.
## I came up with this... Explanations to follow. 

puts 'Please type one word on each line and hit enter...'
puts 'When you get bored, simply hit enter on a blank line.'

words = []
  word = gets.chomp

while word != ''     
	words.push word
	word = gets.chomp
end

puts words.sort

## breaking this code down by line... words = [] simply establishes a new array
## word = gets.chomp defines the variable 'word' and asks for input via the gets method and turns the
## inputs into strings. These strings are then put through the 'while' filter...

## while word!='' ... Essentially what its saying to me is that as long as the input for the variable 'word'
## does not equal a blank (!='') --> take the 'word' variable and push it to the end of the 'words' array 
## (words.push word)

## if the input was not a blank, the program automatically pushes it into our array... so,
## at this point, we need the program to ask us for another input for the 'word' variable
## hence (word = gets.chomp) the second time. 

## if at anytime the input is blank, the program ends and displays a sorted verision of all the 
## strings that were pushed into the array.
