Sorting vowels and consonants

Hey, doing a new asignment that is as follows..
Quote:
/*5. Input text from the user until a sentinel indicates end of input. After the user indicates
that there is no more input, clear the screen and redisplay the input so that the original
word is in one column, vowels are in another column and consonants are in the last
column. Save as lastname_array#5.t.*/


I got the user to enter their words and all that, but i don't know how to sort the vowels and consonants, i know i', supose to use 'index' and the 'lenght' function this is wat i haveso far...
Turing:
var counter : int := 0
var words : array 1 .. 9999 of string
put "Please enter text:End with the word '*'"

for i : 1 .. 9999
    get words (i) : *
    counter := counter + 1
    if words (i) = "*" then
        counter := counter - 1
    end if
    exit when words (i) = "*"
end for

var yeah : array 1 .. counter of string

for i : 1 .. counter
    yeah (i) := words (i)
end for

cls

put "You entered, ", counter, " words."
put ""
put "Word               Vowels               Consonants"
put ""

for i : 1 .. counter
    put yeah (i)
    if index (yeah (i), "aeiouAEIOU") not= 0 then
        put yeah (i)
    end if
end for

so, you have to output all the vowels and the consanants in the input phrase in sorted order ?

a good way of doing this is have an array that stores all the vowels and consanants already preordered.

now, everytime you get to a letter in the input phrase, make it 'checked' on the array..

then, eventually, just wlk through the array and output all the 'checked' vowels and consanants, and since you already preordered the letters, they are guarenteed to be in order.

so how would one precheck them?, thats wat i'm having problems with..

The simplest way of doing this is to manually sort each letter in each word into vowel or consonant, then output.

Once you have your user input, inside the for-loop that goes over each word, you need another for-loop that goes over each letter of the given word. Inside this second loop, check whether that letter is a vowel or consonant and add it to the appropriate string. Once you've done that for each letter in the word, output.

This looks like (pseudocode, you'll need to convert it yourself):

code:

for each word (you have for i : 1 .. counter )
    for each letter in word
        if letter is a vowel then
            vowels := vowels + letter
        else
            consonants := consonants + letter
        end if
    end for
    output word, vowels, consonants all on one line here
end for

just have an array with a preordered copy of all the letters (vowels and consanants).

by 'checking', I mean having a array of boolean that all starts at 'false'....then set it to 'true'
eventually, just output all the elements in the array set to 'true'...

Ok, i did wat you reconmeneded

First, you need to remember to tell us the exact error message when you post (including what line or lines it complains about). Otherwise, we have to copy-paste your code and run it.

Second, read Turing's documentation for what the index() method does. I think you'll find that:
code:
index (yeah(i),"aeiouAEIOU") not =0

doesn't actually determine whether yeah(i) is a vowel or not. It'd be easier to manually check whether yeah(i) is 'a', 'e', 'i', 'o' or 'u'.

Third, you need to check the index you've given in your assignment statements. It doesn't appear to do what you want it to do (it's using the length of string number i as an index into your array of words, which is incorrect).

Post subject:  RE:Sorting vowels and consonants
Addendum: yeah(i) is a string, not a character. You need to test yeah (i) (d), which is character #d of word #i.

Alright so i'm posting this for alex since were in the same programming class but he does not have access to a coputer right now.
This is the code he has so far, it only displays the first vowel and then first consonant of the word.

 that there is no more input, clear the screen and redisplay the input so that the original

var counter : int := 0
var words : array 1 .. 9999 of string
put "Please enter text:End with the word '*'"

for i : 1 .. 9999
    get words (i) : *
    counter := counter + 1
    if words (i) = "*" then
        counter := counter - 1
    end if
    exit when words (i) = "*"
end for

var yeah : array 1 .. counter of string

for i : 1 .. counter
    yeah (i) := words (i)
end for

cls

put "You entered, ", counter, " words."
put ""
put "Word               Vowels               Consonants"
put ""

var vowel, consonant, watever : string := ""

for i : 1 .. counter
    watever := yeah (i)
    for d : 1 .. length (yeah (i))
        if index ("aeiouAEIOU", watever (d)) not= 0 then
            vowel := vowel + watever (d)
        else
            consonant := consonant + watever (d)
        end if
    end for
end for

for i : 1 .. counter
    put yeah (i) : 20, vowel(i) : 20, consonant(i)
end for

Post subject:  RE:Sorting vowels and consonants
Your output is still incorrect. Currently, it will keep track of all the vowels and consonants for ALL of the words in a single variable for each. This isn't what your assignment asks for.

Look more carefully at the flow-of-control I outlined a few posts back. Look where the output occurs.

Secondly, you don't want to output vowel(i) or consonant(i), you want to output vowel and consonant.

okay, so i got it 2 work, but it outputs everything from before as well as the new 'info', is there a way to 'cancel the old output', if you know wat i mean

Post subject:  RE:Sorting vowels and consonants
The problem is that you keep adding to "vowel" and "consonant" without ever clearing the values of either. You can set them each to an empty string by something like this:

code:

vowel := ""
consonant := ""


Now you just need to figure out where to do that.

Okay, so it works for some words and doesn't for others, ...

Works for me.

Kinda cool too :]

Post subject:  Re: Sorting vowels and consonants
Just to add on to Alex's question, words like "house" and "horse" when there inputed in the program together don't work because the consonants are duplicates, they cancel each other out for some reason and just don't show up?

Post subject:  RE:Sorting vowels and consonants
Alright. See up a few posts where I said you should do something like this:

code:

for each word (you have for i : 1 .. counter )
    for each letter in word
        if letter is a vowel then
            vowels := vowels + letter
        else
            consonants := consonants + letter
        end if
    end for
    output word, vowels, consonants all on one line here
end for


You're pretty close, but your output is still incorrect. The reason that we've got the variables 'vowel' and 'consonant' is so that we can save outputting them until after we've figured out what ALL the vowels / consonants we need to list are.

Turing:

var vowel, consonant, watever : string := ""
%var count : int := 0 % Don't need this, you were only using it for output. There's an easier way!

for i : 1 .. counter
    %count := count + 1 % Don't need this
    %locatexy (0, 400 - count)
    %put yeah (i)  % Save this for when we've figured out everything we want to say about that word...
    watever := yeah (i)
    for d : 1 .. length (yeah (i))
        if index ("aeiouAEIOU", watever (d)) not= 0 then
            vowel := vowel + watever (d)
            %locatexy (175, 400 - count) % Save it...
            %put vowel
        else
            consonant := consonant + watever (d)
            %locatexy (360, 400 - count) % Stay on target...
            %put consonant
        end if
    end for

    % Okay, now we can output our results. The :20 part ensures that each takes up exactly 20 spaces
    put yeah (i) : 20, vowel : 20, consonant : 20
    vowel := ""
    consonant := ""
end for
