コード
using System; class Dog { private int weight; private string name; public Dog(int weight, string name) { this.weight = weight; this.name = name; } public int Weight { get { return weight; } } public string Name { get { return name; } } } class Tester { public void Run() { Dog milo = new Dog(26, "Milo"); Dog frisky = new Dog(10, "Frisky"); Dog laika = new Dog(50, "Laika"); Dog[] dogs = { milo, frisky, laika }; string[][] awards = new string[dogs.Length][]; awards[0] = new string[3]; awards[1] = new string[1]; awards[2] = new string[2]; awards[0][0] = "award1"; awards[0][1] = "award2"; awards[0][2] = "award3"; awards[1][0] = "award4"; awards[2][0] = "award5"; awards[2][1] = "award6"; for (int i = 0; i < dogs.Length; i++) { Console.WriteLine("{0}: {1}", dogs[i].Name, dogs[i].Weight); foreach (string award in awards[i]) { Console.Write("{0} ", award); } Console.WriteLine(); } } static void Main() { Tester t = new Tester(); t.Run(); } }
入出力結果(Console Window)
Milo: 26 award1 award2 award3 Frisky: 10 award4 Laika: 50 award5 award6 続行するには何かキーを押してください . . .
ちなみにJavaScriptの場合。
コード(BBEdit)
var Dog = function( weight, name ) { var weight = weight, name = name; this.getWeight = function ( ) { return weight; }; this.getName = function( ) { return name; }; }, milo = new Dog(26, "Milo"), frisky = new Dog(10, "Frisky"), laika = new Dog(50, "Laika"), result = "", dogs = [milo, frisky, laika], awards = { "Milo": ["award1", "award2", "award3"], "Frisky": ["award4"], "Laika": ["award5", "award6"] }, result = "", i, max; for (i = 0, max = dogs.length; i < max; i += 1) { result += dogs[i].getName() + ": " + dogs[i].getWeight() + "\n" + awards[dogs[i].getName()].join(" ") + "\n"; } $('#pre0').text(result);
pythonの場合。
