24.7.14 Split view [range.split]

24.7.14.1 Overview [range.split.overview]

split_­view takes a view and a delimiter, and splits the view into subranges on the delimiter.
The delimiter can be a single element or a view of elements.
The name views​::​split denotes a range adaptor object ([range.adaptor.object]).
Given subexpressions E and F, the expression views​::​split(E, F) is expression-equivalent to split_­view(E, F).
[Example 1: string str{"the quick brown fox"}; for (string_view word : split(str, ' ')) { cout << word << '*'; } // The above prints: the*quick*brown*fox* — end example]
