module main : Every V file must specify which module it belongs to. The entry point of an application must always be in the main module.

You can run the file directly without manually creating a separate binary: v run main.v Use code with caution. Compiling into an Executable

Easily build binaries for Windows, Linux, and macOS from any platform. Getting Started with V Programming (PDF & Installation)

fn main() println('hello world')

fn add(x int, y int) int return x + y fn main() result := add(5, 10) println(result) Use code with caution. Control Structures If-Else Statements

The V programming language is an exceptional choice for developers who value compilation speed, code readability, and lightweight binaries. Its minimal learning curve allows developers transitioning from Python, Go, or C to become productive within a single afternoon.

You can run V files directly using the interpreter-like mode: v run hello.v Use code with caution.

Building V from source ensures you have the latest features and bug fixes. git clone https://github.com cd v make Use code with caution. On Windows: git clone https://github.com cd v make.bat Use code with caution. Verifying the Installation

V can translate your C/C++ code into clean, native V code.

The or block is mandatory when calling a function that returns an optional type. Inside the or block, a special err variable is automatically available, containing the error message. Conclusion
