rust number squared

To square a number in Rust, you can use the pow function from the num crate. First, you need to add num as a dependency in your Cargo.toml file:

[dependencies]
num = "0.4"

Then, in your code, you can use the pow function to square a number. Here's an example:

use num::pow;

fn main() {
    let number = 5;
    let squared = pow(number, 2);
    println!("The square of {} is {}", number, squared);
}

This code imports the pow function from the num crate and uses it to calculate the square of the number variable, which is set to 5 in this example. The result is stored in the squared variable and printed to the console.

The output of this code will be:

The square of 5 is 25
