Day 2: Primitive Types

Today we explore Rust's primitive types - the building blocks of all data in Rust.

What You'll Learn

• Integer types (i32, u64, etc.)
• Tuples and destructuring
• Basic arithmetic operations
• Return values from functions

Rust's Integer Types

Tuples

Tuples group multiple values of different types:

let point = (10, 20);           // type: (i32, i32)
let (x, y) = point;             // destructuring
println!("x: {}, y: {}", x, y);

The Task

Implement calculate(a, b) that returns a tuple of (sum, product).

Requirements

• Take two i32 parameters
• Return (a + b, a * b) as a tuple
• The test uses (7, 6) expecting (13, 42)

Hints

• Return a tuple with parentheses: (value1, value2)
• No semicolon on the last expression = return value
