rust declare multiple mutable variables

In Rust, you can declare multiple mutable variables using the let keyword. Here is an example:

fn main() {
    let mut x = 5;
    let mut y = 10;
    let mut z = 15;

    // Do something with the variables...
}

In this example, the variables x, y, and z are declared as mutable using the mut keyword. This allows you to change their values later in the program. You can then perform any desired operations on these mutable variables.
