functional_crud.rb

# In your Ruby file, run a while loop that presents these options, gets input from a user (as a number), and then acts on this input.
# For example, if the user selects 1, you will add a dish, and so you will take further input from the user and add that into an array.
# Do a similar job for the rest of the options with the appropriate inputs from the user, or the appropriate output.

# write a case statement with the different options
