独習C# 第3版 ハーバート・シルト (著) エディフィストラーニング株式会社 矢嶋聡 (監修, 翻訳)の第2章(C#のデータ型と演算子)の理解度チェック1, 2, 3, 4を解いてみる。
1.
C#で、単純型の範囲と振る舞いが厳密に定義されている理由は、エラーを防ぎ、信頼性を高めるため。
2.
C#の文字型はcharで、シングルクォートで囲む。
C#の文字型が他の多くのプログラミング言語のそれと異なる点は、他の言語では8ビット(ASCII)で表現されるのに対して、C#では16ビット(Unicode)で表現されること。
3.
正しくない。bool型はtrueかfalseで表される。
4.
改行(\n)を使えばいい。せっかくなので逐語的文字列リテラル(@)を使用した場合も。
コード
using System; class Tester { public void Run() { Console.WriteLine("One\nTwo\nThree"); Console.WriteLine("逐語的文字列リテラルを使用"); Console.WriteLine(@"One Two Three"); } static void Main() { Tester t = new Tester(); t.Run(); } }
入出力結果(Console Window)
One Two Three 逐語的文字列リテラルを使用 One Two Three 続行するには何かキーを押してください . . .
