Constants

定数とは数値を表す名称です。

定数は特定の値を表す記述として一ヶ所で定義しておけば、ソースコード上のその定数は全て同じ数値として振る舞います。

例えば年数を表す数値をソースコード上で扱います。その値を2002から2003に変更しようとします。

ソースコード上のあちこちにある2002という記述を2003に変更するよりも、定数"YEAR"をソースコード上に用いておけば、あとから"YEAR"の定義を2002から2003に変更するだけで済むのです。


また、定数は一意の名前を付けることにより、人間が解釈しやすいようにするといった用途でも用いられます。

例えば、白を表す数値(0xFFFFFF)の代わりにWHITEと書いた方が解釈しやすいでしょう。

定数は変数と異なり一定の値をとり、その値を動的に変えることはできません。

コンパイル時にプリコンパイラーがソースコード上の定数を意味するコードを探し出して実際の数値に置き換えます。
