variables

Variables:

• main.rs:

• basic

fn main() {
    let year:i32 = 2021;

    println!("This year is: {} ", year)
}

• storing

fn main() {
    /* storing a variable and printing it out */
    let year:i32 = 2021;
    println!("This year is: {}", year)

    /* again storing another variable inside the defined variable */
    year = 2021;
    println!("Next year is: {}", year)
}
