I'm having problems creating a program that prompts a user to guess the colour.

I'm stuck because my while loop won't end although I wrote a false condition by using count?? The user is supposed to enter 5 characters. And the program is supposed to check whether there are how many correct guesses of colour and position and correct guesses of colour only. How do I do so? Pls help Thanks Im new to matlab

You have

while 1

That will not exit by itself; you need to have a "break" statement inside that loop in order to exit it.

You could be testing count in your "while", such as

while count <= 12345678

but if you do that, be sure to initialize count before the loop, not inside the loop.

clc

% Initiate Random Color Sequence
% r-red; b-blue; y-yellow; g-green; w-white; p-purple; o-orange;
all_colors = 'rbygwpo';
index = randperm(7);
hidden_seq = all_colors(index(1:5));

   count = 0;

while 1
    %Prompting user to enter input
    result = input('Guess the 5 characters colour sequence: ');
    count = count + 1;

      %Validate user input
      if numel(result) > 5 || numel(result) < 5
          error('You have entered more or less than 5 characters')
      end

      %Check the user guesses
     result == hidden_seq 

end

i've placed count before the loop

and how do i use the result from result == hidden_seq

if ans = 1 0 0 0 0

means that there is one correct colour at the first position. how do i print that result since the input changes according to the user and the random sequence of characters generated????

Thanks

find (result == hidden_seq)

gives you the list of matching positions.

What do you want to do with the count? Are you sure you want to change the count if the user does not enter exactly 5 characters? When the user gets everything right, shouldn't you exit the loop?

    end

    %Check the user guesses
        % 1. How many guesses has correct colors and position?
    % 2. How many guesses has correct colors?

   result == hidden_seq

end

sorry for disturbing but I'm so so frustrated after trying for so long. Can you please correct my codes and tell me my mistake big thanks

i'm not changing the count. just leave it for now. i'll attach the question to give you a clearer picture of what i want to do.

It seems like this was an earlier question I did not see when I was answering your duplicate question. So now we have this going on in two discussion threads (not good). See my answer over in your more recent posting: http://www.mathworks.com/matlabcentral/answers/259020-creating-a-program-that-guesses-the-colours-not-a-colour#answer_202294
