year_month ( ) = default ;	(1)	(C++20以降)
constexpr year_month ( const std:: chrono :: year & y, const std:: chrono :: month & m ) noexcept ;	(2)	(C++20以降)

year_month オブジェクトを構築します。

1) デフォルトコンストラクタはyearとmonthを初期化しません。


        year_month

オブジェクトを構築し、年 y と月 m を格納します。

year_month を構築するより便利な方法は、 operator / を使用することです。例えば、 2007y / std:: chrono :: April のように記述します。
