ROOT is a C/C++ based, object-oriented computing framework designed by CERN to efficiently process and analyze large amounts of data, e.g. from high-energy physics experiments. ROOT has an incorporated C/C++ intepreter, CINT, which is written in C++ itself.
The work I did learning C++ was most useful for ROOT. Trying to follow the construction of the Event Analyzer was one thing, creating new macros/scripts for use in ROOT, to facilitate data analysis, was a different matter entirely. My first successful endeavor was a relatively short macro, found on gluey at \home\acarta\ROOT\simplegraph.C, which allows for plotting measurements from a simple .txt file. I spent a good deal of time plotting and fitting measurements taken by Fridah Mokaya. It took me quite a while to get used to the objects and classes in ROOT, which differ from standard C++, as well as the various options and procedures for creating plots in ROOT. Especially troublesome was the use of the TCanvas objects, in particular trying to add multiple plots to the same canvas.
