Fortran calls C++ functions:
in Fortran, the arguements are passed by reference,
in C++ prototype, the arguements can be declared as
pointer generally. I also tried passing reference in C++,
it works. (Here only consider a single unit built-in data type, e.g. real,
integer)
My question is: why it works for both passing reference and passing pointer?
(ONLY test on FC4, intel fc/cc 9.0)

IMHO, reference is essentially the same as pointers, since it is passing the
address not the value

why lots of programmer are using pointer instead of reference?
I think refernece is better than pointer if only passing int, double ... data
type.

It looks nicer to use reference than pointers, plus you do not need to
dereference pointers all the time.
