on line 41, you can see the first two parameters are hardcoded. If I try to use .zip on cust_lat and cust_long in the File.open() block, there's no error but the values are completely wrong. What is the correct way to get cust_lat and cust_long into the block without hardcoding? NOTE: line 43 works as is.

distance.rb

require 'csv'
require 'haversine'

#read existing fiber latitudes from CSV
fib_lat = CSV.read("fib_lat.csv")

#read existing fiber longitudes from CSV
fib_long = CSV.read("fib_long.csv")

#read potential customer latitudes from CSV
cust_lat = CSV.read("cust_lat.csv")

#read potential customer longitudes from CSV
cust_long = CSV.read("cust_long.csv")

#get latitudes for potential customers, store in c_lat array
c_lat = []
cust_lat.each do |c|
    c_lat << c
end

#get longitudes for potential customers, store in c_long array
c_long = []
cust_long.each do |c|
    c_long << c
end

#get latitudes for existing fiber, store in lat array
lat = []
fib_lat.each do |f|
    lat << f
end

#get longitudes for existing fiber, store in long array
long = []
fib_long.each do |f|
    long << f
end

#create a file named distance-ouput.csv, iteratate through lat long arrays at same time using zip
File.open('distance-output.csv', 'w') do |csv_object|
    lat.zip(long).each do |lat_locs,long_locs|  
        csv_object << Haversine.distance(28.59569, -81.21464, lat_locs.pop.to_f, long_locs.pop.to_f).to_feet
        csv_object << "\n"
    end
end
