Challenge 1 — Solution

Task: Write a program that declares title (string), pages (int), and
inStock (bool) using := for each, then prints all three using a
single fmt.Println call.

package main

import "fmt"

func main() {
	title := "The Hobbit"
	pages := 310
	inStock := true

	fmt.Println(title, pages, inStock)
}


Expected output:

The Hobbit 310 true

Notes:
- Each := infers its own type from the value on the right: title
  becomes a string, pages an int, inStock a bool — no type is ever
  written explicitly here.
- fmt.Println accepts any number of arguments of mixed types and
  prints them space-separated on one line, the same as it did with
  a string and a number in Chapter 1.
- true/false in Go are lowercase keywords, not strings — they print
  without quotes.
