constexpr value_type operator[]( difference_type pos ) const     requires ranges::random_access_range<Base>;		(seit C++23)

Gibt ein Element an einer angegebenen relativen Position zurück.

Äquivalent zu: return *(*this + pos);.

Parameter

pos

-

Position relativ zur aktuellen Position

Rückgabewert

Das Element (vom Typ value_type) mit dem Versatz pos relativ zur aktuellen Position.

operator* (C++23)

greift auf das Element zu (öffentliche Memberfunktion)
