Command line arguments - print all args

• std::env

• args

• Vec

• We load the std::env module

• #[allow(clippy::needless_range_loop)] is needed to silence clippy, the linter

use std::env;

fn main() {
    let args: Vec<String> = env::args().collect();
    println!("My path is {}", args[0]);
    println!("Number of arguments is {}", args.len());

    #[allow(clippy::needless_range_loop)]
    for i in 1..args.len() {
        println!("Parameter {} is '{}'", i, args[i]);
    }
}
