If someone's hard drive is full and they want to see which programs are hogging all the space, will you advise them to write a `C` program?\\

Absolutely not.\\

You will advise them to use the `du` and `sort` commands.

(If your response is that `du` and `sort` are themselves written in `C`, my rebuttal is that `perl` and `python` are themselves written in `C`.)
