To run this program, save it in a file named hello.v , then execute it using the V compiler:
fn main() score := 85 // If-Else Expression result := if score >= 50 'Pass' else 'Fail' // Match Expression (Replaces Switch) grade := match score 90...100 'A' 80...89 'B' else 'F' println('Result: $result, Grade: $grade') Use code with caution.

fn divide(x f64, y f64) ?f64 if y == 0 return error("division by zero")
V manages heap allocations using an mechanism. The compiler automatically inserts free statements for objects at the end of their scope during compilation. This prevents memory leaks and removes the latency spikes associated with traditional garbage collection. 8. Concurrency Model
// Imports import os read_file, input import math pi
struct User name string mut: is_active bool pub: id int // Method associated with the User struct fn (u User) greet() println('Hello, my name is $u.name') fn main() mut me := Username: 'Bob', id: 101, is_active: true me.greet() Use code with caution. Interfaces
It achieves safety through immutability by default, bounds checking, and optional memory management modes.
fn main() println('Hello from the world of V!')
The growing community around V has created fantastic supplementary resources. One of the most popular is , an open-source project available on GitHub ( github.com/v-community/v_by_example ). It teaches V through a series of annotated example programs, covering everything from basic control flow to more complex data structures like arrays and structs. This "learning by doing" approach is an excellent complement to the more formal book and documentation.
If you want a full script to of this guide using V's native markdown tools.
