main.rb
require 'csv'

# Use the `foreach` method to read the file line by line
CSV.foreach('my_data.csv') do |row|
  # Each `row` is an array of columns in the CSV file
  puts row.inspect
end

# Alternatively, you can read the whole file into memory using the `read` method
csv_data = CSV.read('my_data.csv')

# `csv_data` is now an array of arrays, where each inner array represents a row in the CSV file
csv_data.each do |row|
