What is Rust - Hands-On Activity

What is Rust

📖 Scenario: You are curious about a programming language called Rust. You want to learn what it is and see a simple example of how to write and run a Rust program.

🎯 Goal: Learn what Rust is and write a simple Rust program that prints a message to the screen.

📋 What You'll Learn

Create a Rust program with a main function

Print a message explaining what Rust is

Use correct Rust syntax for printing

Understand the basic structure of a Rust program

💡 Why This Matters

🌍 Real World

Rust is used to build fast and reliable software like web browsers, games, and operating systems.

💼 Career

Knowing Rust can help you work on system-level programming jobs that require safety and performance.

1

Create the main function

Write a Rust fn main() function to start your program.

Rust

fn main() {
    // Your code here
}

Need a hint?

The main function is the entry point of a Rust program. It looks like fn main() { }.

2

Add a print statement

Inside the main function, add a println! macro to print the message "Rust is a systems programming language.".

Rust

fn main() {
    // Your code here
}

Need a hint?

Use println!("message"); to print text in Rust.

3

Explain Rust in a comment

Add a comment above the println! line explaining that Rust is safe and fast.

Rust

fn main() {
    // Your code here
    println!("Rust is a systems programming language.");
}

Need a hint?

Comments start with // in Rust.

4

Run the program and show output

Run the Rust program and print the output it produces.

Rust

// Run the program and print the output below
// Your code here

Need a hint?

The program prints the message exactly as given.
