Anatomy of a Go Program

Every Go file follows a specific structure:

  1. Package Declaration: package main tells Go this is an executable.
  2. Imports: Bringing in external or standard library code.
  3. Main Function: func main() is the entry point.

go package main

import "fmt"

func main() { fmt.Println("Cloud-Native Go!") }

Run it with go run main.go.
