I don't speak C#, but since it's similar to Java, the same may apply: Java
(object) methods are by default virtual, while in C++ methods are by default
non-virtual.

Yeah, I think they are commonly mixed. AFAIK the correct nomenclature would be
"formal parameter" for what is declared in the function signature and "actual
parameter" or "argument" for a value that is passed to a the function. But
usually, whatever term you use, it is clear what you mean.
