Go methods

This program demonstrates methods in Go. Unlike traditional OOP languages, Go attaches methods to types using a receiver parameter. Here, the greeter struct has a greet() method with a value receiver (g greeter). When called, the method has access to the struct’s fields and can format a greeting message.

package main

import (
	"fmt"
	// "strconv"
	// "math"
	// "reflect"
	// "net/http"
	// "log"

)


type greeter struct {
	greeting string
	name string
}

func (g greeter) greet() {
	fmt.Printf("%v: %v\n", g.greeting, g.name)
}

func main()  {
	a := greeter{
		greeting: "Hello",
		name: "Gooers!",
	}

	a.greet()
}
