Okay, so PLEASE bare with me here. I'm very new to Matlab (literally learning it today), and I'm just trying to learn the basics. All I know is a little bit of Java/C++, so I'm having a hard time adjusting to this. What I'm trying to do is make a hangman game without the plotting/graph of man getting hung. I'm randomly selecting a color and then asking the user to guess the letters. I'd like to place the user inputted letter into an element in an array, so that when I use "strfind" in my for loop I can display previous user inputted characters. The problem I was having is this: Let's say the color is blue, so the program inserts _ _ _ _ and asks the user to choose a letter and then the user would choose 'b' let's say so then the output would be "b _ _ _" - now the problem I was having is the next step; let's say the user inputs "l" now - the program would output "___ l _ _" and not retain the "b" from the previous. Therefore, I thought to put the user input into an array that is being searched into a for loop, so that whenever the user inputs anything it will search all the elements in the array to see if any previous characters were made. Sorry if that's confusing; I'm trying my best to explain. And again, please bare with me, as I really don't know what I'm doing and I have NO IDEA how arrays are handled in Matlab (the only concept of arrays I have is from Java/C++) The code is below:

a = 8;
numWrong = 0;
index = '0';
again = 'Y';
count = 1;
disp('Lets Play!')
      while(again == 'Y')
          p = randperm(a);
          for i=1:8
              r = p(i);
          end;
          disp(r);
          switch(r)
              case 1
                  word = 'blue';
                  wordCount = 4;
              case 2
                  word = 'green';
                  wordCount = 5;
              case 3
                  word = 'red';
                  wordCount = 3;
              case 4
                  word = 'black';
                  wordCount = 5;
              case 5
                  word = 'yellow';
                  wordCount = 6;
              case 6
                  word = 'orange';
                  wordCount = 6;
              case 7
                  word = 'purple';
                  wordCount = 6;
              case 8
                  word = 'gray';
                  wordCount = 4;
          end;
            for i= 1: wordCount
                disp('___');
            end;
            while(numWrong < 6)
            disp(['You have ' num2str(6-numWrong) ' guesses']); 
            letter = input('Please choose a character a-z: ','s');
            character{count} = letter; %trying to place letter into array "character" in element specified by the count
            count = count + 1;
            isFound = false;
            for i=1: wordCount
                for k=1: wordCount
                    letter = character(k); %trying to put info from array back into variable, so I can use it for strfind
                 if(strfind(word,letter) == i) %this is where I find errors.
                    disp(character(k));
                    isFound = true;
                else
                    disp('___');
                 end;
                end;
                end;
            if(isFound == false)
                numWrong = numWrong + 1;
            end;
            num = num + 1;
            end;
            if(numWrong == 6)
                disp('GAME OVER, better luck next time!');
            end;
          again = input('Would you like to play again? (Y/N): ','s');
      end;
