Module 8: Structs

Practice Tasks

Complete these tasks to reinforce what you learned in this module.

Task 1: Struct and field access

Define a struct Person with fields name: String and age: u32. Create an instance with name "Alice" and age 30, then print both fields.

Expected Output:

Hint: Define a struct with the two fields; for name you need an owned string (see the ownership module). Create an instance with the struct literal syntax.

Starter Code:

task.rs

// Task 1: Struct Person. See tasks/TASKS.md.

fn main() {
    todo!("Define Person, create instance, print name and age");
}

Task 2: impl method

Add an impl block for Person with a method greet(&self) -> String that returns format!("Hello, I'm {} and I'm {} years old.", self.name, self.age). Create a Person, call greet(), and print the result.

Expected Output:

Hint: Methods go in an impl block; use &self to borrow the struct. Use format! for the string; the expected output tells you the name and age to use.

Starter Code:

task.rs

// Task 2: impl greet. See tasks/TASKS.md.

fn main() {
    todo!("Add impl Person with greet(), call and print");
}
