just something I cooked up real quick to show Art ruby's expressive power after he had done this same project in C++

contacts.rb

#!/usr/bin/env ruby -wKU

class Contact
    attr_accessor :name, :address, :city, :state, :zip_code, :phone
    
    def initialize( name, address, city, state, zip_code, phone )
        @name, @address, @city, @state, @zip_code @phone = name, address, city, state, zip_code, phone
    end
    
    def to_s
        foo = "Name: #{name}\n"
        foo << "Address: #{address}\n"
        foo << "City: #{city}\n"
        foo << "State: #{state}\n"
        foo << "Zip Code: #{zip_code}\n"
        foo << "Phone: #{phone}\n"
    end
end

puts "Welcome to Contact Book"
print "Enter your name: "
name = gets.strip
print "Enter your address: "
address = gets.strip
print "Enter your city: "
city = gets.strip
print "Enter your state: "
state = gets.strip
print "Enter your zip_code: "
zip_code = gets.strip
print "Enter your phone: "
phone = gets.strip

contact = Contact.new name, address, city, state, zip_code, phone

puts "\nContact: \n#{contact.to_s}"
