 not quite true. "Passed by value" means, clearly enough, passing
values, but "pass by reference" does not actually mean using a
reference variable. It means passing a pointer ("reference") to
that structure, data type, etc. and is widely used in C. Reference
variables are C++ specific, but "r.v." is actually a confusing
term, as the word "reference" is not used in that sense in any
other part of the language. There, the reference is from programmers point
of view, you have a variable which may be manipulated just like the real
target, but it is actually defined elsewhere. "Normal" use of the
word "reference" means a referencing from the view point of
machine itself, a variable holds a value telling where the another one is.
