Fixed C++ style on refactored function and variable names.

As described on
https://google.github.io/styleguide/cppguide.html#Function_Names :

"Ordinarily, functions should start with a capital letter and have a
capital letter for each new word (a.k.a. "upper camel case" or "Pascal
case")."

and

"Data members of classes (but not structs) additionally have trailing underscores. "
