# Quiz Exercise, Part One
#
# Quiz for a name and birthday,
# then display the age
#
# For example:
#
#   Hey there! Please enter your name:
#   > John
#
#   Thanks. When is your birthday, John?
#   > 10/13/2000
#
#   You are 13 years old.



##
## OUTLINE
##

# We're going to want to break the problem down into steps.
# First, let's ask for the user's input:
#

puts "Hey there! Please enter your name:"

# How do we prompt for input from the keyboard in Ruby?
name = 'John'


# BIRTHDAY
# OK, now birthday

puts "Thanks. When is your birthday, John?"

birthday = '10/13/2000' # TODO: ask for the user to type in a birthday


# AGE
# We have to calculate this based on their birthday
#
# Tip: solve a couple real-life problems in your head:
# If I told you I was born in 1976, how would you calculate how old I am?
#
# Hints:
# * How do we extract just the age from a string like '10/13/2000'?
# * How would we perform arithmetic on the string '2000'?
# * You can just hard-code the current year, "2013", into your script, and replace it later with the computer's clock time


age = 13 # TODO: calculate the age

puts "You are 13 years old." # TODO: display calculated age



##
## FINISHING UP
##

# * Does your script ask for user input? Will it run with examples
#   other than "John" and "10/13/2000?"
#
#
# * Are there line breaks any place you don't want them? e.g.:
#
#     You are 13
#     years old
#
#   ? How do we remove line breaks in Ruby?
#
#
# * Is the age calculation correct when the birthday is after the current date?
#   What happens if you enter the birthday "12/29/1950"

## EXTENSION #1
##

# Extensions are optional.
# Don't worry if you don't have time to complete them.

# Display a checklist of things they're able to do:
#
# * Are they eligible for a driver's license?
# * Are they allowed to join the military?
# * Are they allowed to buy alcohol?
# * Are they eligible for a senior citizen discount?
#
# Example output:
#
#   Driver's license: YES
#   Military: YES
#   Alcohol: NO
#   Senior citizen: NO






##
## EXTENSION #2
##

# How would we use the Ruby Time library to perform the arithmetic using Time objects?
#
# Hint: you'll need to add this line of code to the top of your script
# to get access to all of Ruby's time functionality:
#
#   require 'time'
#
