I had a problem about string

[at20092009]

var cha : string
var a, b, c, d := ""
put "Enter a series of characters: "
const vowels := "aeiou"
const word1 := "abcdefghijklmnopqrstuvwxyz"
const word2 := "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
loop
get cha
put ""
for i : 1 .. length (cha)
if index (vowels, cha (i)) = 0 and index (word1, cha (i)) not= 0 or index (word2, cha (i)) not= 0 then
a := a + cha (i)
put "consonant - ", a ..
put ""
elsif index (vowels, cha (i)) not= 0 then
b := b + cha (i)
put "vowel - ", b ..
put ""
elsif strintok (cha (i)) then
c := c + cha (i)
put "number - ", c ..
put ""
else
d := d + cha (i)
put "any other character - ", d ..
put ""
end if
end for
end loop


This is my program, but it is different from the sample of the question.

The example is, if I type "asdfert456u2~1?",
it will show

numbers - 45621
vowels - aeu
consonants - sdfrt
any other character - ~?

Your program is going to output "consonants - " every time it finds a consonante. You only want it to print once, don't you? How do you think you would fix that? Same with all your other categories, to be honest.

[at20092009]

yea, i just want to show consonante once, I tried to use " .. " to fix it, but it didn't work.

[at20092009]

still, i can't fix it

[Insectoid]

Do you know why it's printing more than once?

[at20092009]

Cause it is in the loop, so it will repeat putting the consonante, but there's no way to move this put command away from the if part, that won't work.

[Insectoid]

Yes, that's why, and yes, there is a way. You'll need a few extra variables but your code really won't even change much.

[at20092009]

extra variables?! OK, I'll try it! Thx!
