constexpr reference operator[](index_type idx) const;

Returns a reference to the idx-th element of the sequence. The behavior is undefined if idx is out of range (i.e., if it is greater than or equal to size()).

Parameters

idx

-

the index of the element to access

Return value

A reference to the idx-th element of the sequence, i.e., data()[idx]

Exceptions

(none)
