Fork this repository, and clone the fork to your local computer. Edit this README.md file to contain the answers, and then make a pull request on Github to turn in the assessment.

Question 1

a = 5
b = 4
a = b

At the end of this program, what are the values of a and b? Try to explain, in plain English, how you got your answer for each one.

a = 4, b = 4. at the end of the code the value of a is reset to the value fo b, which is 4

Question 2

e = 3
f = 9
g = e + f
f == g
e = 3

At the end of this program, what are the values of e, f, and g? Try to explain, in plain English, how you got your answer for each one.

e = 3, f = 12, g = 12. at the end of the code g = e(3) + f(9) then f is set equal to g and e is reset to 3

Question 3

weather = "cloudy"
weather == "cloudy"

What is the difference between these two statements? Explain your answer.

the first statement is setting a value to weather the second value is comparing the variable to the string (false)

Question 4

x = 2

if x == 3
  puts "sushi is tasty"
elsif x > 0
  puts "sushi is delicious"
end

Imagine that you take the code from this question, save it to a file called sushi.rb, and run ruby sushi.rb in your Terminal.

What would be the output? Explain your answer.

the code would return "sushi is delicious" because its x != 3 but is greater than 0

Question 5

food = "walnut"

if food == "walnut"
  puts "I'm allergic!"
end

Imagine that you take the code from this question, save it to a file called snack.rb, and run ruby snack.rb in your Terminal.
