I have an exercise in logic but I have not been able to understand how to do it
I have a txt file with the answer question format and a line break where it follows that same format:
1-question
answer
- jump line -
2-question
answer
- jump line -
etc ....
the idea is to read that txt file and show the question in the console and then the user can answer it if it is ok, continue with the next question if he does not show the question again.
I do not know if I made myself understood.
If the question file format always will be the same, you can do something like this:
questions = File.readlines('preguntas.txt')
questions.each_slice(3) do |question, answer, _|
loop do
puts question
given_answer = gets.chomp
break if given_answer == answer.strip
end
end
readlines reads the file and returns an array where each element is a line. each_slice(3) iterates the array in blocks of 3, leaving the first line in the variable question , the second line in answer and the third one in _ (which we ignore as a blank line). loop always shows the same question until the user puts the correct answer.
