Examples

let small: i8 = 127
let count: i32 = 1000000
let big: i64 = 9223372036854775807
let temp: f32 = 36.5
let pi: f64 = 3.14159
let flag: bool = true
let greeting: string = "hello"
let generic: ptr = nil
let len: usize = 42

String Operations

let s = "Hello"
print(s.length)          // 5
let full = s + " World"  // "Hello World"

Escape Sequences
