How to print out a variable in rust

To print out a variable in Rust, you can use the println! macro. Here's an example:

fn main() {
    let my_variable = 42;
    println!("The value of my_variable is: {}", my_variable);
}

This code defines a variable called my_variable with a value of 42. The println! macro is then used to print out the value of my_variable using the {} placeholder within the string. When the code is executed, it will output:

The value of my_variable is: 42

You can replace my_variable with the name of your own variable, and modify the format string and placeholders as needed to print out different types of variables.
