Hi i am having some problems

[shruti]

hi guys i am new. i have a question. i wrote this program where the output should be in alphabetical order but i am having some errors i dont know what it is. anotehr question is that if we have to replace every 4th cahracter in a word ...how to you do it ??? is there a formula or something ???????????

Quote:

var word:string
var word1 : string
var word2 : string
var word3 : string
put " please enter the first word ex, cappa "
get word1
put " please enter the second word ex, alpha"
get word2
put " please enter the third word ex, beta"
get word3
if (word1>word2) and (word1>word3) then
put "The words in alphabetical order "
elsif (word2<word1) or (word2>word3) then
put "The words in alphabetical order "
elsif ( word3<word1) or ( word3<word2) then
put " the words in alphabetical orders are ", word1, word2, word3
elsif (word1=word2) and (word1=word3)then
put " words are the same, smart !"
elsif ( word2=word1) and (word2=word3) then
put " words are the same, smart !"
elsif ( word3=word1) and (word3=word2) then
put " words are the same, smart!"
end if
put "The words in alphabetical order ", word1, word2, word3
get word1, word2, word3


i know that put "The words in alphabetical order ", word1, word2, word3" i shopuld not put word1..3 but i dont know what to do m

plzzzzzzzzzzzzzzz help me ASAP
thankyou

what kind of error are you having?

also... this makes little sense

code:

put "The words in alphabetical order ", word1, word2, word3 get word1, word2, word3

[shruti]

its not exactly an error but if i put some words that's not in alphabetical order. it outputs word1,2,3. in the order taht i put

[Tony]

well you did say specifically that

put "The words in alphabetical order ", word1, word2, word3

what did you expect it to output there?

[shruti]

i want the output to be that the words should be in alphbetical orderlike if you put ksr it will give what ever you put in but i want it in alphbetical order

To start off, it's best to use an array when your holding 3 of the same thing.
And it's also alot easier to manipulate later, and when you want to do it with 10 words.

The reason that it puts them back out in the same order is because that is what your having it do.

Turing:

if (word1>word2) and (word1>word3) then put "The words in alphabetical order "  % this is all that it sais here, it doesn't say to output them at all in a different order. elsif (word2<word1) or (word2>word3) then put "The words in alphabetical order " % same here elsif ( word3<word1) or ( word3<word2) then put " the words in alphabetical orders are ", word1, word2, word3  % Now you have it outputting the words when the case= true, but its still 1,2,3 elsif (word1=word2) and (word1=word3)then put " words are the same, smart !" elsif ( word2=word1) and (word2=word3) then put " words are the same, smart !" elsif ( word3=word1) and (word3=word2) then put " words are the same, smart!" end if put "The words in alphabetical order ", word1, word2, word3 % you are now outputting them in the same order and haven't changed the order in any way

Also get rid of the get word1, word2, word3 at the very end because it does nothing.

Now in order to properly sort the list a simple bubble sort will do. But in order to use the bubble sort you need the words in an array.
firstly declair your array, and the temporary variable you need for the bubble sort.

Turing:

var word := array 1..3 of string var temp :string

now to call them use either a "for" statement or word(1),word(2)...
now that you have the words in its time to sort. Heres the bubble sort and how to use it

Turing:

for i:1..3 % the max of the array    for ii:1..2 % the max of the array-1       if word(ii)>word(ii+1) then  %so if the previous word is greater than the word after it then          temp:=word(ii)          word(ii):=word(ii+1) % these 3 things are switching word(ii) and word(ii+1) around          word(ii+1):=temp       end if    end for end for put "The words in alphabetical order: ".. for i: 1..3    put word(i)," ".. end for put"" % stops the line continuation

Now theres probably a better method but to change the 4th letter you can do it like this

Turing:

for ii : 1 .. 3 % 1.. the number of words     for i : 1 .. length (word (ii)) % 1 to the number of characters in the word         if i = 4 then % if your on the 4th character             put "k" .. % put the 4th character as k replace k with what ever you want         else % if its not 4 then just put the letter that suppose ot be there             put word (ii) (i) ..         end if     end for     put "" end for

hey the Bean when i put the 1st command there is an errror i dont know why !
it says "syntax error at array"

an for the 2nd one there is also an error and it should be every 4th letter ! the error is " variale has no value " ...
plx help me
