Understanding a Minimal Rust Program

Rust is a modern programming language that has gained popularity in recent years. It is known for its speed, memory safety, and concurrency features. If you are interested in learning Rust, you can start by understanding a minimal Rust program.

A minimal Rust program consists of a main function that prints "Hello, world!" to the console. Here's what the code looks like:

fn main() {

   println!("Hello, world!");

}

The first line defines the main function. The second line uses the println! macro to print "Hello, world!" to the console. The third line closes the main function.

To run this program, you need to have Rust installed on your computer. You can download Rust from the official website and follow the installation instructions. Once Rust is installed, you can create a new Rust project and add the code to the main.rs file. Then, you can run the program using the cargo run command.

By understanding this minimal Rust program, you can start exploring more advanced Rust concepts and building your own Rust projects. Happy coding!
