Understand it, then run it

Todayrust
// This program demonstrates the `char::is_control` method, which was stabilized
// in Rust 1.97.0. It prints whether the newline character is considered a
// control character. The output is shown below.
fn main() {
    let c = '\n';
    // Use `{:?}` to display the character as an escaped string.
    println!("Is {:?} a control character? {}", c, c.is_control());
}

What it printed when we ran it on Rust 1.98.1 (edition 2024)

Is '\n' a control character? true

Run sends this program (for Solidity, the contract and its tests) to our own sandbox, where it is compiled and run once, with no network, and what it printed or the test report comes back here. Nothing is kept. Runs are counted per visitor for the day so everyone gets a turn; the details are on the legal page.
