The guessing game from the Rust book
use std::io;
use std::cmp::Ordering;
use rand::Rng;
fn main() {
println!("Guess the number!");
let secret_number = rand::thread_rng().gen_range(1, 101);
loop {
println!("Please input your guess.");
let mut guess = String::new();
io::stdin().read_line(&mut guess).expect("Failed to read line");
let guess: u32 = match guess.trim().parse() {
Ok(number) => number,
Err(error) => { println!("{}", error); continue }
};
println!("You guessed: {}", guess);
match guess.cmp(&secret_number) {
Ordering::Less => println!("Too small!"),
Ordering::Greater => println!("Too big!"),
Ordering::Equal => { println!("You win!"); break; }
}
}
