NAME
     std::filesystem::path::filename - std::filesystem::path::filename

Synopsis
	path filename() const;	(since C++17)

Example
     // Run this code

      #include <filesystem>
      #include <iostream>
      namespace fs = std::filesystem;

      int main()
      {
	  std::cout << fs::path("/foo/bar.txt").filename() << '\n'
		    << fs::path("/foo/.bar").filename() << '\n'
		    << fs::path("/foo/bar/").filename() << '\n'
		    << fs::path("/foo/.").filename() << '\n'
		    << fs::path("/foo/..").filename() << '\n'
		    << fs::path(".").filename() << '\n'
		    << fs::path("..").filename() << '\n'
		    << fs::path("/").filename() << '\n'
		    << fs::path("//host").filename() << '\n';
      }

Output:
      "bar.txt"
