Example

// Run this code

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

  int main()
  {
      fs::path p = fs::current_path();

      std::cout << "The current path " << p << " decomposes into:\n"
                << "root name " << p.root_name() << '\n'
                << "root directory " << p.root_directory() << '\n'
                << "relative path " << p.relative_path() << '\n';
  }

Possible output:

  The current path "C:\Users\abcdef\Local Settings\temp" decomposes into:
  root name "C:"
  root directory "\"
  relative path "Users\abcdef\Local Settings\temp"
