Head First Go (Jay McGavren(著)、O'Reilly Media)のChapter 1(let's get going - Syntax Basics)、Code Magnets(18)の解答を求めてみる。

コード

package main

import "fmt"

func main() {
 var originalCount int = 10
 var eatenCount = 4
 fmt.Println("I started with", originalCount, "apples.")
 fmt.Println("Some jerk ate", eatenCount, "apples.")
 fmt.Println("Tere are", originalCount-eatenCount, "apples left.")
}

入出力結果(Bash、cmd.exe(コマンドプロンプト)、Terminal)

$ go run sample3.go
I started with 10 apples.
Some jerk ate 4 apples.
Tere are 6 apples left.
