  Convert this description:
  
  src is a parent directory that houses 2 subdirectories: hello and main.
  At the main level, 'hello' features 2 subdirectories: cpp, headers.
  At level 2, in directory path 'hello → cpp', Inside 'cpp', you'll find it is currently empty.
  At level 2, in directory path 'hello → headers', The 'headers' folder has been left empty.
  In the root directory, 'main' encapsulates 1 contained folders: cpp.
  Within directory hierarchy 'main / cpp', Inside 'cpp', you'll find it sits empty.
  Back to the top level.
