Alright having problems with string now, tried to do it but couldn't figure it out. I've done some of it but not all of it. Question: Write a Turing program that accepts a word typed at the keyboard. Your program will then create the pattern illustrated like this one: word o__ r r__ o Ignore the ___'s. drow var word : string % Tells you to enter a word put "Enter word: " .. get word % Determines how much letters are in the words put word, " has ", length (word), " letters." put "" % Top row % Right row % Bottom row % Left row for i : 1 .. length (word) put word (i) end for

Re: String Problem

You can use code tags:

code:

[code]word
o r
r o
drow[/code]

gets you

code:

word
o r
r o
drow

Anyhow, the first and last rows are obvious.
The middle rows will follow a pattern: (2nd letter) ((length - 2) spaces) (2nd-to-last letter), etc.

Said there were 3 errors, and 2 warnings.

Okay, got it. But they put a random word, so it won't be the letter word that will be there, can be anything.

RE:String Problem

Okay, I finished it. The code to do it is:

code:

var word : string
var current_line : int := 5
word := "word"
put ""
% Tells you to enter a word
put "Please enter a word: " ..
get word
% Determines how much letters are in the words
put "The word '", word, "' has ", length (word), " letters."
put ""
% Top Row
put word
% Left Row
for i : 2 .. length (word)-1
put word (i)
end for
% Bottom Row
for decreasing i : length (word) .. 1
put word (i) ..
end for
% Right Row
for decreasing a : length (word)-1 .. 2
locate (current_line, length (word))
put word (a)
current_line := current_line + 1
end for

Opps, made a mistake. Here's the right one:

Turing:

% Variables
var word : string
var current_line : int := 5

% Tells you to enter a word
put "Please enter a word: " ..
get word

% Determines how much letters are in the words
put "The word '", word, "' has ", length (word), " letters."
put ""

% Top Row
put word

% Left Row
for i : 2 .. length (word)-1
put word (i)
end for

% Bottom Row
for decreasing i : length (word) .. 1
put word (i) ..
end for

% Right Row
for decreasing a : length (word)-1 .. 2
locate (current_line, length (word))
put word (a)
current_line := current_line + 1
end for
