Calculator Challenge

You have been tasked with creating a program that runs in the command line (bash). The program should ask for 2 numbers, a mathematical operator, and then execute the operation on the two numbers.

How It Works

Can be run using bash (i.e. ruby yourfile.rb)
Asks the user to input a number (i.e. 10)
Asks the user to input another number (i.e. 5)
Asks the user to input a mathematical operator (i.e. +)
Outputs the the result of the computation (i.e. 15.0)

app/models/user.erb

class User < ActiveRecord::Base

  # All of the fields listed here are required
  validates_presence_of :email, :avatar_url, :username, :password

  # All of these fields must be unique (i.e. can't register the same email twice)
  validates_uniqueness_of :email, :username

Deploying Finstagram to Heroku

These instructions will help you deploy your Finstagram app to Heroku (a web hosting service), so that the entire internet will be able to see and interact with your application! Before we get to deployment though, we need to make sure a couple of our files are setup properly.

Pre-Deployment: Edit Your Gemfile

Ensure your Gemfile file contains the following code (should match exactly).

source "https://rubygems.org"

gem 'rake'
gem 'activesupport'

	# STRINGS
	# # we can use double quotes
	puts "This is a string."
	# # or we can use single quotes
	puts 'This is a string with single quotes.'
	# # adding two strings together
	puts 'Hello, ' + "Maggie."

	#INTEGER
	#we can add them

	# Our program should
	# - make a list of numbers from 1 to 100 (inclusive)
	# - for each number:
	# print "Fizz" if divisible by 3
	# print "Buzz" if divisible by 5
	# print "FizzBuzz" if divisible by 3 AND 5
	# otherwise, print the number


	# uncomment the block of code you want to run to test each version

	def number_label(number)
	if number % 5 == 0 && number % 3 == 0
	"#{number} FIZZBUZZ"

	elsif number % 5 == 0
	"#{number} BUZZ"

	elsif number % 3 == 0
	"#{number} FIZZ"

	# Write a method called "yellowpager" that accepts a 10-character string of
	# letters and outputs a corresponding phone number string. If the input letter
	# string isn't 10 characters, you should return false. Not valid.

	# 2 -> A B C
	# 3 -> D E F
	# 4 -> G H I
	# 5 -> J K L

	def map_letters_to_numbers(user_input)

	user_output = ""
	user_input.upcase!

	if user_input.length == 10
	user_input.each_char do \|letter\|
	case letter
	when("A".."C") then user_output += "2"
	when("D".."F") then user_output += "3"

	class Song

	def initialize(title)
	@title = title
	end

	def play
	puts "Now playing #{@title}"
	end
