Head First Go (Jay McGavren(著)、O'Reilly Media)のChapter 1(let's get going - Syntax Basics)、Pool Puzzle(10)の解答を求めてみる。

コード

package main

import (
 "fmt"
)

func main() {
 var originalCount int = 10
 var eatenCount int = 4

 fmt.Println("I started with", originalCount, "apple.")
 fmt.Println("Some jerk ate", eatenCount, "apples.")
 fmt.Println("There are", originalCount-eatenCount, "apples left.")
}

入出力結果(cmd(コマンドプロンプト)、Terminal)

C:\Users\...>go run sample2.go
I started with 10 apple.
Some jerk ate 4 apples.
