Answer 2

fn print_type_of<T>(_: &T) {
    println!("{}", std::any::type_name::<T>());
}

fn main() {
    let (a, b, c, d) = (1, "Rust", 3.14, -309801);
    
    println!("{} {} {} {}", a, b, c, d);
    
    print_type_of(&a);
    print_type_of(&b);
    print_type_of(&c);
    print_type_of(&d);
}

   
     
/*
run:

1 Rust 3.14 -309801
i32
&str
f64
i32
   
*/
