How to solve undefined error

ruby-talk
1

My program as follow:
subjectName = {}
subjectMark = {}
n = 1
while n <= 3
puts 'Enter the subject name'
subjectName = gets.chomp

puts 'Enter the subject marks'
subjectMark = gets.to_i
n +=1;
end

subjectName.each {|key, value|
        puts " #{subjectName} ==>#{subjectMark}" }

I am trying to run above program, I got undefined error like:

" marksheet.rb:14:in `<main>': undefined method `each' for "t":String
(NoMethodError) "

I can't able to get above error.

How can I get desire output?

Thank you.

Please read how Hashes works, and then try again. Your mistake was in case where you’re changing type of Hash to String asigning your hash var with gets.chomp.

the solution could be like this(fast and sketchy way):

subject_store = {}
marks = []
subjects = []

3.times { puts ‘Enter subject name’; subjects << gets.chomp }
3.times { puys ‘Enter subject marks’; marks << gets.to_i }
subject_store = Hash[marks.zip(subjects)]
subject_store..each {|key, value|
puts " #{subjectName} ==>#{subjectMark}" }
