fn main() name := 'Alice' // Immutable string inference mut age := 25 // Mutable integer age = 26 // Allowed // name = 'Bob' // Will cause a compiler error println('$name is $age years old.') Use code with caution. Basic Data Types V includes standard primitives: bool (true/false) string (UTF-8 encoded strings) i8 , i16 , int , i64 (Signed integers) u8 , u16 , u32 , u64 (Unsigned integers) f32 , f64 (Floating-point numbers) Control Flow
// Same type arguments can be grouped fn sub(a, b int) int return a - b getting started with v programming pdf updated
module main
To demonstrate V's real-world capabilities, let's build a functional, high-performance web server using the built-in vweb module. Create a file named server.v : Getting Started with V Programming, published by Packt
This comprehensive, updated guide will help you master the basics of V programming. If you prefer an offline reference, you can easily save this complete guide as a PDF through your browser's print option ( Ctrl+P or Cmd+P > Save as PDF). 1. Why Choose V?
V can automatically translate your existing C or C++ codebases into clean V code. 2. Core Philosophy and Design Patterns If you prefer an offline reference, you can
Open your terminal and run the following commands. V bootstraps itself quickly.
Use := to declare and initialize a variable.
