What have you tried? What do you consider whitespace?

What kind of a problem are you having with this? (trying to find where whitespace is; removing a character at a known location; etc)

if you read my problem it says i cant remove spaces. ive used this code but it outputs the letters on different lines if the word has spaces. e.g "h e y" outputs

h
e
y

Turing:

var word : string var newword : string := "" procedure remove_spaces (user_word : string)     newword := ""     for x : 1 .. length (word)         if index (" ", word (x)) = 0 then             newword += word (x) + ""         end if     end for     put newword end remove_spaces loop     get word     remove_spaces (word) end loop

newword += word (x) + ""

get rid of the + ""

By default, get word will treat any whitespace as the end of the input. To include whitespace, up to the maxium string length, use get word : *. The asterisk is a wildcard meaning take as many characters as possible, however it could be replaced with a number specifying the maximum characters to include in the input.

Also, one suggestion to improve your program: local variables are always better than global variables. For example:

Turing:

procedure remove_spaces (user_word : string)     var newword : string := "" % local, also no redundant assignment     for x : 1 .. length (word)         if index (" ", word (x)) = 0 then             newword += word (x) % unnecessary + "" as mentioned         end if     end for     put newword end remove_spaces loop     var word : string % local, and passed to remove_spaces as a parameter     get word : * % include whitespace     remove_spaces (word) end loop

Right. Didn't think that one through.
