Week 2 Assignments

Total time estimated: 4-10 hours

##Ruby Reading 1-2 hours

You may optionally want to look at Ruby section of the resources page for more reading. Below are selected suggestions from that page:

• Chapters 1-6 of Learn to Program by Chris Pine. This one is very clear and straightforward. If the website is ever down, we shared a Google Drive folder with you which has the book printed to PDF.
• Why's Poignant Guide Chapter 3 - Ruby Basics. So beloved, so absurd. Much mnemonic.

Assignment 3 - Ruby Koans

2-5 hours

Your assignment is to complete a portion of the Ruby Koans. Specifically, you should complete all the koans through the section (i.e. file) called triangele_project.rb (~1/2 of them).

If you would like to have them run automatically, you could try to use the trick described here: https://github.com/neo/ruby_koans/#running-the-koans-automatically

Sometimes a "point" comes from completing multiple lines - pay close attention to which line the koan is pointing at to prevent frustration.

If you don't understand something in the koans, you should try these in order:

1. Try to figure it out by trying things in the koans environment
2. Look it up
3. Make a note to figure it out later

##Assignment 4 - Grandma 1-3 hours

Write a Deaf Grandma program.

• Whatever you say to grandma (whatever you type in), she should respond with HUH?! SPEAK UP, SONNY! , unless you shout it (type in all capitals).
• If you shout, she can hear you (or at least she thinks so) and yells back, NO, NOT SINCE 1938! or other silly grandma phrases she has in her small repertoire.
  • To make your program really believable, have grandma shout a different year each time; maybe any year at random between 1930 and 1950.
• You can't stop talking to grandma until you shout BYE. Except she doesn't want you to leave, so you have to shout BYE three times in a row.
  • Make sure to test your program: if you shout BYE three times, but not in a row, you should still be talking to grandma.
• Hints
  • Don't forget about chomp! 'BYE'with an Enter is not the same as 'BYE' without one!
  • Try to think about what parts of your program should happen over and over again. All of those should be in your while loop.
