Is there a tutorial?
Changed:

Yes. A popular one is written by Prof. William Seligman of Columbia University. His home page is an interesting read (click the small "cornify" button at the bottom a few times for a real treat). The tutorial has developed over the past 13 years, and appears to have been created for a 2-day REU seminar. The tutorial can be found here: ROOT tutorial. (Unfortunately, you won't be able to complete all of the exercises because we don't have access to Prof. Seligman's files).

No. Here are some examples of computer languages.
  What is ROOT?
Changed:

ROOT is an object-oriented computer program (a "data analysis framework") written in C++ that was created by these 2 physicists at CERN to replace the FORTRAN computer library in 2003. It was originally designed for particle physics data analysis, but is now in heavy use in astro-particle physics experiments such as HESS, VERITAS, Ice Cube, Milagro, Fermi and at the Pierre Auger Observatory.
