cpp/filesystem/path/begin

@1@ Returns an iterator to the first element of the path. If the path is empty, the returned iterator is equal to end. @2@ Returns an iterator one past the last element of the path. Dereferencing this iterator is undefined behavior.

The sequence denoted by this pair of iterators consists of the following:
 * 1)  (if any)
 * 2)  (if any)
 * 3) sequence of s, omitting any directory separators
 * 4) If there is a directory separator after the last  in the path, the last element before the end iterator is an empty element.

Parameters
(none)

Return value
@1@ Iterator to the first element of the path. @2@ Iterator one past the end of the path
