Concatenate strings using format!

• format!

• In this case all the strings are copied so it is less efficient than where we move the string, but this means we can continue to use the original variables.

fn main() {
    let string1 = String::from("Apple");
    let string2 = String::from("Banana");
    let str3 = "Peach";

    let text = format!("{}-{}-{}-{}", string1, string2, str3, "other");
    println!("{}", text);
    println!("{}", string1);
    println!("{}", string2);
    println!("{}", str3);
}
