Show a letter in its right locations

Hello everybody! I'm programming something with matlab and I need your help! For example: Tokyo has 2 "o"! I know how to hide the word tokyo but if the user enters "o" I don't know how to show the 2 "o"! An example of execution: --> * * * * * --> Enter a letter: 'o' --> * o * * o

Here's a simple hangman game I banged out in about 3 minutes. Adapt as needed.

% Simple hangman game.
correct = 'tokyo';
revealed = '*****';
defaultValue = '*';
titleBar = 'Enter a Letter';
userPrompt = 'Enter the Letter';
while ~strcmp(revealed, correct)
  % Ask user for a letter.
  caUserInput = inputdlg(userPrompt, titleBar, 1, {num2str(defaultValue)});
  % Bail out if they clicked Cancel.
  if isempty(caUserInput),return,end; 
  % Convert from cell array to character.
  usersLetter = char(caUserInput);
  % Find locations that match the user's letter.
  matches = correct == usersLetter;
  % Change those locations from * to the actual letter.
  revealed(matches) = usersLetter
  % Change prompt to update revealed.
  userPrompt = sprintf('%s\nEnter another Letter', revealed);
end
msgbox('You finished!');

Incredible..wooow! I'm new in matlab (not even 2 months with 2h per week)! But I'm not supposed to know how to right a program like this! I'm asked to write a hangman game as simple as possible with "while" "if" "for" etc....Please can you help me? If you speak french I can send you directly my program and you correct me! If you don't speak french, I can translate some parts that need it!

I already did help you. Probably too much since I didn't know it was a class assignment because you didn't tag it as homework. I'll add that tag for you. Please read this: http://www.mathworks.com/matlabcentral/answers/8626-how-do-i-get-help-on-homework-questions-on-matlab-answers
