C++ strings

Hey /prog/,

I need your help. I'm a beginner in C++ and I've been doing some exercises. I got stuck when asked to find a word made only with vowels. So far my program can find all vowels in the text but I've no idea how check if a word consists only of vowels.
I'm working with STL strings. I've tried google but everything's too confusing to me atm.

Please help.

The D Programming Language

int i;
char allVowels = 1;
for(i = 0; i < strLength; ++i){
    if(! isVowel(str[i])){
        allVowels = 0;
        break;
    }
}
if(allVowels){
    //do whatever
}

STRINGS? WHAT ARE THESE STRINGS YOU SPEAK OF?

>>3
Using char instead of _Bool or int.
IHBT.

>>4
why would i use 4 bytes when i can use 1?
and bool? lol, this is C, not java.

OP here.
Maybe this will help:
void FindWord (string S) {

    string word;
    string::size_type start(0);
    string::size_type end;
    end = S.find_first_of(Cdelim, start);

    while(end != string::npos) {
        word = S.substr(start, end - start);
        CheckWord(word);
        start = end + 1;
        end = S.find_first_of(Cdelim, start);
    }
    word = S.substr(start);
    CheckWord(word);
}

void CheckWord (string Z) {
    size_t found;
    string word;
    found = Z.find_first_of(Cvowels);
    while(found != string::npos) {
        word = Z[found];
        found = Z.find_first_of(Cvowels, found+1);
     }
    cout << word ;
    cout << endl;
}

Don't come crying to me when your critical loops are slow as molasses

int f(char *s) { return !s[strspn(s, "aeiou")]; }

>>7
>critical loops
>OP is clearly doing simple string exercises

YHBT

No sage, incorrect invocation of the quote environment, I think this guy might be from the imageboards.

i am not a bbcode master

>>11

Hint: It's not BBCode.

>>1
:3 mfw I realise that innocent soul of OP is currently being corrupted by C++ strings. No \b[aoieu]+\b regexpes for him! :3:3:3

>>10
Let's fork(2) him.

>>13

It's still obvious that you're from the imageboards.

>>3
Have I mentioned that I advertise on /b/ only with the purpose of giving you something todo?

>>14

>>11 =/= >>13
fyi

>>16
Faggot != detected.

>>17
thank you

>>14
your still a faggot


bool all_bowels(string::const_iterator start, end) {
  return (start == end) ? true :
         aintvowel(*start) ? false :
         allbowels(s, ++start);}

Doesn't work? Who cares, it's Sepples.

main = interact $ unlines . filter (all (`elem` "aeiouAEIOU")) . words

>>19
you're*
