rustHow do I add a variable to a string in Rust?

Adding a variable to a string in Rust is done using the format! macro. This macro allows you to insert variables into a string.

Example code

let name = "John";
let message = format!("Hello, {}!", name);
println!("{}", message);

Output example

Hello, John!

The code above consists of three parts:

1. let name = "John"; - This declares a variable called name and assigns it the value "John".

2. let message = format!("Hello, {}!", name); - This uses the format! macro to insert the value of the name variable into the string "Hello, {}!".

3. println!("{}", message); - This prints the value of the message variable to the console.
