1. Introduction to Rust

Introduction

Hey, I heard Rust is a popular programming language. What's it all about?

Rust is a systems programming language designed for safety, concurrency, and performance.

Sounds cool! Can you show me a simple example using Rust?

Of course! Let's start with the famous "Hello, World!" program.

Step 1: Installing Rust

First, we need to install Rust, right?

Exactly! You can install Rust using the official installation guide at https://www.rust-lang.org/tools/install.

Step 2: Creating a New Rust Project

Now that Rust is installed, what's next?

Great question! We'll create a new Rust project using the command line.

cargo new hello_world
cd hello_world

Step 3: Writing the “Hello, World!” Program

I'm ready! Let's write the "Hello, World!" program!

Sure thing! Open the "main.rs" file inside the "src" folder, and write the following code.

fn main() {
    println!("Hello, World!");
}

Step 4: Running the Program

Now let's run our program!

You got it! In the command line, type "cargo run" to run the program.

cargo run

Output:

Hello, World!

Conclusion

Congratulations! You’ve just written and run your first Rust program. Keep exploring and learning, and you’ll become a Rustacean in no time! 😄
