rustHow to format multiline string in Rust

In Rust, you can format multiline strings using the format! macro. This macro allows you to create a string with placeholders that can be replaced with values.

Code example:

let name = "John";
let age = 30;

let multiline_string = format!("My name is {},
I am {} years old.", name, age);

println!("{}", multiline_string);

Output

My name is John,
I am 30 years old.

Explanation of code parts:

1. let name = "John";: This line declares a variable name and assigns it the value "John".
2. let age = 30;: This line declares a variable age and assigns it the value 30.
3. let multiline_string = format!("My name is {}, I am {} years old.", name, age);: This line uses the format! macro to create a multiline string with placeholders for the values of name and age.
4. println!("{}", multiline_string);: This line prints the multiline string to the console.
