Note: I'm getting some hate from others who think I would pick or prefer COBOL over a modern language. I wouldn't. I was making an outside-the-box "devil's advocate" objective observation. I just wanted to preface that here. Okay, the rest of my original comment remains below:

The irony is that we already had a memory safe and stable language in Cobol that was easier to read and understand than Rust. But, no one wants to use it so it is "dead" but it runs everything that made the modern age possible.

RUST:

println!("Enter number: ");

let mut input_string = String::new();

io::stdin().read_line(&mut input_string).unwrap();

let number: i32 = input_string.trim().parse().expect("Please enter a valid number.");

let result = if number % 2 == 0 {

    "EVEN"

} else {

    "ODD"

};

println!("The number: {}", result);

COBOL:

display 'Enter number: '

accept number

if function mod(number,2) = 0

    move 'even' to result

else

    move 'odd' to result

end-if

display 'The number: ',result
