A small program that takes a word (String) as input and translates it into Pig Latin

pig-latin

use std::io;

fn main() {
    let mut input = String::new();
    loop {
        io::stdin().read_line(&mut input)
            .expect("Failed to read line");
        input = input.trim().to_string();
        piglatinize(&mut input);
        println!("{}", input);
        input.clear();
    }
}

fn piglatinize(s: &mut String) {
    let initial_letter = s.remove(0);
    if !is_vowel(initial_letter) {
        s.push(initial_letter);
        s.push_str("-ay");
    } else {
        s.push_str("-hay");
    }
}

fn is_vowel(c: char) -> bool {
    c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u'
