Multiple Variables - Alternate Syntax
The alternate syntax uses multiple empty {}
curly bracket placeholders and the variables
outside the quotes as before. The first variable
goes into the first {}. The second variable
goes into the second {} and so on.
It looks like this:
fn main() {
let alfa = String::from("apple");
let bravo = String::from("berry");
let charlie = String::from("cherry");
println!("{} {} {}", alfa, bravo, charlie);
}
which produces the same output:
apple berry cherry
