      1) Returns an iterator to the first element of the path. If the path is empty, the returned iterator is equal toend().
      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. root-name (if any).
      2. root-directory (if any).
      3. Sequence offile-names, omitting any directory separators.
      4. If there is a directory separator after the lastfile-name in the path, the last element before the end iterator is an empty element.

      [edit]Parameters

      (none)

      [edit]Return value

      1) Iterator to the first element of the path.
      2) Iterator one past the end of the path

      [edit]Exceptions

      May throw implementation-defined exceptions.

      [edit]Example

      Run this code
      #include <filesystem>#include <iostream>namespace fs= std::filesystem; int main(){const fs::path p=#   ifdef _WIN32"C:\\users\\abcdef\\AppData\\Local\\Temp\\";#   else"/home/user/.config/Cppcheck/Cppcheck-GUI.conf";#   endifstd::cout<<"Examining the path "<< p<<" through iterators gives\n";for(auto it= p.begin(); it!= p.end();++it)std::cout<<*it<<" │ ";std::cout<<'\n';}

      Possible output:

      --- Windows ---Examining the path "C:\users\abcdef\AppData\Local\Temp\" through iterators gives"C:" │ "/" │ "users" │ "abcdef" │ "AppData" │ "Local" │ "Temp" │ "" │ --- UNIX ---Examining the path "/home/user/.config/Cppcheck/Cppcheck-GUI.conf" through iterators gives"/" │ "home" │ "user" │ ".config" │ "Cppcheck" │ "Cppcheck-GUI.conf" │
