strings

clear 
clc

 word=lower(double(input('Enter a character \n')));

 letter = char(input('Guess a character : ','s'));

 stat = findstr(word,letter);

I'm trying to get the user to enter any number of character(not case sensitive). Then enter any random character and see if it matches any character of their first input.

What are you trying todo??

You said that 'trying to get the user to enter any number'.

But your code :

word=lower(double(input('Enter a character \n')));

Now, how can I use command 'lower' with numerical (double) input??

command lower works only for string, right??

I thought lower was to not make it not case sensitive. And I'm trying to get the user to any character, not just numbers.

Did you mean??

clear; clc;

   word = lower(input('Enter a word : ','s'));
   letter = input('Guess a character : ','s');
   stat = findstr(word,letter);
   if ~isempty(stat)
       for x = 1 : length(stat)
           fprintf('Character %c macthes with word %s in column %d\n',letter,word,stat(x));
       end
   else
       fprintf('Character %c no found in word %s\n',letter,word);
   end

Yep, exactly what I meant, thank you!

Answer 2

[Sven Schoeberichts]

word = input('Enter a word: ', 's'); 
letter = input('Guess a character : ','s');
stat = ismember(letter,lower(word));

stat = 1: character is present in word

stat = 0: character is not present in word

Okay, I may should have been more specific. Suppose the word I input is loop. And I guess the letter o. I expect a return of 0 1 1 0. 1 representing the number of times o is in the word.
