发帖数: 160 | 1 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)

address not the value

发帖数: 160 | 3 why lots of programmer are using pointer instead of reference?
I think refernece is better than pointer if only passing int, double ... data
type.

发帖数: 113 | 4 It looks nicer to use reference than pointers, plus you do not need to
dereference pointers all the time.
