Hi there!
I just started learning Rust yesterday. I am trying to read stdin until the user says end.
use std::io;
fn main() {
let mut input = String::new();
while input != "end\n"{
println!("Say something: ");
io::stdin().read_line(&mut input).expect("failed to read line");
println!("You said: {}", input);
}
}
For some reason every new line of input just gets appended to the previous lines:
Say something:
one
You said: one
Say something:
two
You said: one
two
Say something:
end
You said: one
two
end
Say something:
Why does that happen? of course, i could declare input inside the while loop or something like that but I want to know why it behaves like this..
TIA,
Michi
