tuples_refs

Instructions

  • Define a tuple struct to represent a Student. Each is identified by an id of type i32, their first name and last name.

  • Then define three functions to return the id, first name and last name.

pub fn id(student: &Student) -> i32 {
}

pub fn first_name(student: &Student) -> String {
}

pub fn last_name(student: &Student) -> String {
}

Usage

Here is a program to test your functions

use tuples_refs::*;

fn main() {
	let student = Student(20, "Pedro".to_string(), "Domingos".to_string());
	println!("Student: {:?}", student);
	println!("Student first name: {}", first_name(&student));
	println!("Student last name: {}", last_name(&student));
	println!("Student Id: {}", id(&student));
}

And its output:

$ cargo run
Student: Student(20, "Pedro", "Domingos")
Student first name: Pedro
Student last name: Domingos
Student Id: 20
$
