/*
Exercise: HTTP Handlers

Implement the following types and define ServeHTTP methods on them. Register them to handle specific paths in your web server.

type String string

type Struct struct {
    Greeting string
    Punct    string
    Who      string
}
For example, you should be able to register handlers using:

http.Handle("/string", String("I'm a frayed knot."))
http.Handle("/struct", &Struct{"Hello", ":", "Gophers!"})
*/

package main

import (
    "fmt"
    "net/http"
)

type String string

func (s String) ServeHTTP(    
    w http.ResponseWriter,
    r *http.Request) {
	fmt.Fprint(w,s)
}

type Struct struct {
    Greeting 	string
    Punct 		string
    Who			string
}

func (s Struct) ServeHTTP(
    w http.ResponseWriter,
    r *http.Request) {
    fmt.Fprint(w,"%s %s %s",s.Greeting,s.Punct,s.Who)
}


func main() {
   	http.Handle("/string",String("I'm a frayed knot."))
    http.Handle("/struct",&Struct{"Hello",":","Gophers!"})
    http.ListenAndServe("localhost:4000", nil)
}
