What is the Atom shortcut for quickly finding a file (fuzzy finder)?

Task E- The Command Line:

screenshots of your terminal after each exercise will be posted in comments

Day One Questions:

What does pwd stand for, and how is this command helpful? pwd stands for print working dictionary and it's helpful because it allows you to see what directory you're in if you get lost while you're working.
What does hostname tell you, and what shows up in YOUR terminal when you type hostname? The hostname command tells you your computer's network name. Daniels-MBP.domain shows up when I type this command.

Task F- Learn Ruby:

Option 1 Questions:

IRB

How do you start and stop irb? irb to start and exit to stop
What might you use irb for? to experiment with small pieces of code to see if certain features will work before using them in your program

Variables

How do you create a variable? type the name of the variable on the left side, then a = , and the desired value on the right
What did you learn about the rules for naming variables? variables cannot start with numbers or contain dashes and it must contain letters
How do you change the value of a variable? to change the value of a variable name simply type the name of the variable followed by a = and assign the new value on the right side

Datatypes

How can you find out the class of a variable? .class
What are two string methods? include? downcase!
How can you change an integer to a string? to_s

Strings

Why might you use double quotes instead of single quotes in Ruby? You would want to use double quotes when you need to use string interpolation
What is this used for in Ruby: #{}? String Interpolation: Used to plug in a variable into a string
How would you remove all the vowels from a string? Use .delete methods and 'aeiou'' inside of ()

Input & Output

What do 'print' and 'puts' do in Ruby? Displays a string to the user of the program
What does 'gets' do in Ruby? gets input from user and leaves a space after
Add a screenshot in the comments of the program you created that uses 'puts' and 'gets', and give it the title, "I/O".

Numbers & Arithmetic

What is the difference between integers and floats? floats contain decimals
Complete the challenge, and post a screenshot of your program in the comments with the title, "Numbers".

Booleans

What do each of the following symbols mean?
- == equals
- = greater than or equal to
- <= less than or equal to
- != not equal to
- && and
- || or
What are two Ruby methods that return booleans? .end_with? and .include?

Conditionals

What is flow control? when code makes decisions for us
What will the following code return? Not many apples...

apple_count = 4

if apple_count > 5
  puts "Lots of apples!"
else
  puts 'Not many apples...'
end

What is an infinite loop, and how can you get out of one? a loop that never stops because the condition being tested is never met, Ctrl + C to get out of it
Take a screenshot of your program and terminal showing two different outputs, and post it in the comments with the title, "Conditionals".

nil

What is nil? nothing
Take a screenshot of your terminal after working through Step 4, and post it in the comments with the title, "nil".

Symbols

How can symbols be beneficial in Ruby? symbols are useful when trying to save memory within a program
Does naming symbols use the same rules for naming variables? as far as I can tell yes
Take a screenshot of your terminal after working through Step 4, and post it in the comments with the title, "Symbols".

Arrays

What method can you call to find out how many elements are in an array? .length
What is the index of pizza in this array: ["pizza", "ice cream", "cauliflower"]? 0
What do 'push' and 'pop' do? push adds an element to the end of an array and pop removes it and returns the value

Hashes

Describe some differences between arrays and hashes. arrays only require a value while hashes require a key and a value
What is a case when you might prefer an array? What is a case when you might prefer a hash? I think I would prefer a hash when storing data that is related to each other or when they share the same properties
- Take a screenshot of your terminal after working through Step 2, and post it in the comments with the title, "Hashes".

Were you able to get through the work? Did you rush to finish, or take your time?
What are you most looking forward to learning more about?
What topics would you most like to see reinforced by instructors?
What is most confusing to you about what you've learned?
What questions do you have for your student mentor or for your instructors?
