# Remember: use `ruby exercise3.rb` to run this file

# 1. display the contents of the `my_variable` variable
my_variable = "100"

# 2. assign the integer 5 to a variable named 'number'

# 3. display the contents of the 'number' variable

# 4. change (coerce) the string in 'my_variable' into an integer

# 5. put the coerced string, now an integer, into a variable named 'new_number'

# 6. display the contents of the 'new_number' variable

# 7. add 'number' to 'new_number' and assign it to a variable named 'sum'

# 8. create an array with the values 1, 2, 4, and 5, assign it to a variable named `numbers`

# 9. display the contents of the array at index 1

# 10. display array element (contents) at index 10

# 11. use `each_with_index` to display the number and index for the `numbers` array

# 12. put a comment here that says what kind of operation `each_with_index` is
#   Hint: comments start with a `#`

# 13. create a hash with the keys of one, two, three, four, five and the values of 1, 2, 3, 4, 5
#   Hint: "one" => 1

# 14. use `each` to display the key and value for each member of the hash
#  Question: did you remember to put the hash in a variable?

# 15. change the display of the hash to say:
# "The value of 'one' is 1" for each member of the hash, so 'two' is 2, and 'three' is 3, etc.
