**Course Title:** Mastering Rust: From Basics to Systems Programming **Section Title:** Introduction to Rust and Setup **Topic:** Writing your first Rust program: Hello, World! **Introduction** In the previous topics, we covered the basics of Rust, including its history, goals, and use cases, setting up the development environment, and exploring the basic syntax. Now that we have a solid foundation, it's time to write our first Rust program. In this topic, we'll dive into creating a classic "Hello, World!" program, exploring the key concepts and best practices that will help you get started with Rust programming. **Creating a New Project with Cargo** In the previous topic, we installed Rustup and Cargo, the Rust package manager. Cargo is an essential tool for managing Rust projects, and we'll use it to create our first project. To create a new project, open a terminal or command prompt and navigate to the directory where you want to create your project. Run the following command: ```bash cargo new hello_world ``` This will create a new directory called `hello_world` containing the basic structure for a Rust project. **Understanding the Project Structure** Navigate into the `hello_world` directory and take a look at the files and directories created by Cargo: ```bash hello_world/ Cargo.toml src/ main.rs .gitignore ``` Here's a brief explanation of each file and directory: * `Cargo.toml`: This is the configuration file for Cargo. It contains metadata about your project, including its name, version, and dependencies. * `src/`: This directory contains the source code for your project. * `main.rs`: This is the entry point for your program, where you'll write the code to execute when your program runs. * `.gitignore`: This file specifies files and directories that Git should ignore. **Writing the Hello, World! Program** Open the `main.rs` file in your preferred text editor or IDE and replace the existing code with the following: ```rust fn main() { println!("Hello, World!"); } ``` Here's what's happening: * `fn main()`: This defines a function named `main`, which is the entry point for your program. * `println!("Hello, World!");`: This prints "Hello, World!" to the console. **Running the Program** To run your program, navigate to the `hello_world` directory and run the following command: ```bash cargo run ``` This will compile your program and run it. You should see the following output: ``` Hello, World! ``` Congratulations! You've just written and run your first Rust program. **Key Concepts and Takeaways** * Use Cargo to create new projects and manage dependencies. * Understand the basic project structure, including `Cargo.toml`, `src/`, `main.rs`, and `.gitignore`. * Write a basic `main` function to execute when your program runs. * Use `println!` macro to print output to the console. **Practical Exercise** Try modifying the `main.rs` file to print a different message to the console. Experiment with different types of strings, such as concatenating strings using the `+` operator or using string formatting. **Resources** *Official Rust documentation on Cargo: https://doc.rust-lang.org/cargo/ *Official Rust documentation on the `println!` macro: https://doc.rust-lang.org/std/macro.println!.html **Help and Feedback** If you have any questions or need help with this topic, please leave a comment below. In the next topic, we'll cover the fundamentals of ownership and borrowing rules in Rust, which will help you write more efficient and effective code. Please proceed to the next topic: "Understanding ownership and borrowing rules."
