Day 1: Hello Rust

Welcome to your Rust journey! Today we'll write our first Rust program and learn the fundamentals.

What You'll Learn

• Declaring variables with let
• Basic string types
• The println! macro for output
• String interpolation with {}

The Task

Create a variable called name with the value "Rustacean" and print a greeting message.

Key Concepts

Variables

In Rust, variables are declared with let:

let x = 5;           // immutable by default
let mut y = 10;      // mutable with 'mut'

The println! Macro

Use println! to print to the console:

let name = "World";
println!("Hello, {}!", name);  // Output: Hello, World!

Requirements

• Create a variable name with the value "Rustacean"
• Print exactly: Hello, Rustacean! Welcome to Rust.

Hints

• Use let to declare the variable
• Use println! with {} for interpolation
• The string must be a &str literal (in quotes)
