Finding the average number of guesses

Write a program, ImprovingGuessing.m, in which the guessing game automatically repeats over and over until the user quits. Add the ability for the user to quit the program by inputting a “q” or a “0”. At that point, print out the average number of guesses.

This is what I have for the code, but I am stuck on how to find the average number of guesses. Any help would be appreciated. Thank you.

right=randi(20);

disp('I am thinking of a number between 1 and 20') 
Number_of_guesses= 0; 
guess=0 ; 



while (guess~= right)
    b=input ('Do you want to guess again? q for NO, 1 for YES'); 
    if b==0; 
        break; 
    else 
        Number_of_guesses=Number_of_guesses +1; 
        guess= input('Guess the number:\n');
        if guess> right 
            fprintf('Too high\n') 
        elseif guess< right 
            fprintf('Too low\n', guess); 
        else 
            fprintf('You guessed it! Congrats!\n', right)
            fprintf ('It took you %d guesses to get it correct\n', Number_of_guesses) 
        end 
    end 
end

In the lines:

            fprintf('Too low\n', guess); 

and

            fprintf('You guessed it! Congrats!\n', right)

there is an argument, but no corresponding format string. Omit the trailing argument.

All you need is an additional loop:

ready   = false;
nLoop   = 0;
nAnswer = 0;
while ~ready
    ... Your code
    nLoop   = nLoop + 1;
    nAnswer = nAnswer + Number_of_guesses;
    s = input('Type ''q'' if you want to quit...', 's');
    ready = strcmpi(s, 'q');
end

Now you have the number of answers and the number of loop. This is sufficient to get the average number of answers.
