Rust - read STDIN - remove trailing newline (trim, chomp)

• trim_end

• to_owned

• trim_end removes trailing whitespace.

• to_owned Converts the &str to String to be able to assign to the name variable again.

use std::io;

fn main() {
    let mut name = String::new();

    println!("Please type in your name:");
    io::stdin()
        .read_line(&mut name)
        .expect("Failed to get input");

    name = name.trim_end().to_owned();

    println!("Hello {name}, how are you?");
}
