Make a quiz in matlab

I have questions for my quiz like this example

questions = {'How many earth? '
             'Is 7 a prime number? '
             'How much water in glass? ' }

How to add the answer key?, my answer key is

         How many earth = one
         Is 7 a prime number = yes
         How much water in glass = Not identify

the answer key is used to give a correction for the answer.

Example : when I answer 'no' for 'Is 7 a prime number?', the statement 'incorrect' will apper under the answer, but if I answer 'yes', the statement will be 'correct'

questions = {'How many earth? '
             'Is 7 a prime number? '
             'How much water in glass? ' } ;
answers = {'one' , 'yes', 'Not identify'} ; 
N = length(questions) ; 
prompt = 'Answer: ' ; 
for i = 1:N
  fprintf(questions{i},'%s') ; 
  user_answer = input(prompt, 's') ; 
  if strcmpi(answers{i},user_answer)   % compare answer 
    fprintf("Correct\n",'%s')
  else
    fprintf("Incorrect\n",'%s')
  end
end
