From High-Level to Systems Programming: A Practical Guide to Rust

Hashnode prompted me to make this comment. Very accessible! It wasn't clear to me why ? is needed here:

fn main() {
    let result = divide(10, 2)?;
    println!("The result is {}", result);
}

What happens without it?

The implementations of take_ownership and give_it_back are the same. Is that intentional?

Much better than me sharing my own notes, which you can barely follow. Thanks for this guide.

Hi I want to be learn high level programming how can i do?
