uuuh ... why so ?

to suffer more :-P
and write as explicitly as possible, never initializing a variable on the same line it's declared and stuff like that

yes (° w ^)

Fine, forbidden keyword.

Satisfied? XD

we couldn't use for loops but only while loops

uuuh ... why so ?

it was an inside joke because we attended together a school where we couldn't use for loops but only while loops, so that's the "forbidden function" :-P anyway my solution is crap because it wouldn't scale up to more than 2 digits

there's not even a function call here ? ...

I'm pretty sure this is not possible (only mods can erase solutions and they do it in few compulsory cases).

Use of forbidden function

Final grade: -42

There was a way to edit your solution and make it not be visible but I genuinely forgot how

anyways hello \o/

PLEASE STOP BRINGING ATTENTION TO THIS AWFUL LEAKING CODE.

I CAN CONFIRM THAT MY ATTENTION WAS BROUGHT TO THIS, DESPITE NOT KNOWING ANY C, DUE TO THE CAPS AND SUBSEQUENT COMMENTS BY PROMINENT CODEWARS USER ROWCASED

IT WILL NOT BE IGNORED IF YOU BRING ATTENTION TO IT

IGNORE THIS I FORGOT TO FREE THE MEMORY AT THE END PEPEHANDS

It's an array of a single character which holds the amount of vowels.

For some reason.

God knows why they didn't just give a variable but you know, it doesn't matter.

Thus is an incorrect solution pls ignore
