How to use Array in Ruby? -

i newbie in ruby. trying write simple interactive game in ruby stuck. need proceed. below concept:

money         = [100, 200, 300, 400] beneficiaries = ["john", "sam", "mary"] cost1         = [50, 25, 30, 75, 18] cost2         = [120, 150, 200, 250] gift1         = [" crayon ", " pencil ", " biro "] gift2         = [" bag ", " shoe ", " radio "] cashowned     = [50]             = money.sample b             = cost1.sample c             = cost2.sample d             = gift1.sample e             = gift2.sample f             = cashowned puts " hi, name? " puts name = gets.chomp puts puts " #{name} nice name." puts puts "#{name} have #{f} in bank account." puts puts "roll dice , let's see how earned." puts gets.chomp.to_i dice1 = puts "#{name} earned: #{dice1}" puts gets.chomp.to_i cashowned = dice1 + f puts "your account balance : #{cashowned}" puts gets.chomp.to_i 

i stuck here. want repeat/loop sequence can give out gift @ cost , deduct cash owned. cash owned not updating. simpler way go appreciated. thanks.

ruby case sensitive language.

fist declared variable as:

cashowned = [50] 

and later trying update using variable name:

cashowned = dice1 + f 

note "cashowned" , "cashowned" different variables

update:

line 7, have:

cashowned = [50]  

my question is, why not use only:

cashowned = 50 

?

as doing cause error: array can't coerced fixnum (typeerror)

you trying sum fixnum array.

see code:

money = [100, 200, 300, 400] beneficiaries = ["john", "sam", "mary"] cost1 = [50, 25, 30, 75, 18] cost2 = [120, 150, 200, 250] gift1 = ["crayon", "pencil", "biro"] gift2 = ["bag", "shoe", "radio"] cashowned = 50 = money.sample b = cost1.sample c = cost2.sample d = gift1.sample e = gift2.sample f = cashowned puts "hi, name?" name = gets.chomp puts "#{name} nice name." puts "#{name} have #{f} in bank account." puts "roll dice , let's see how earned." gets.chomp.to_i dice1 = puts "#{name} earned: #{dice1}" gets.chomp.to_i cashowned = dice1 + f puts "your account balance : #{cashowned}" gets.chomp.to_i 

and see test result:
