When you actually take a look at the bulk of FORTRAN, it looks suspiciously like C -- and it has C linkage. So, to me personally, I lump FORTRAN and C together in my head and then the question becomes &quot;What real advantage does the switch to C++ from C have for you?&quot;. You can find vast amounts of information on the web to answer that question :)<p>I have not known a single person in over a decade to go out and specifically learn FORTRAN as a separate language. Schools still provide graduates with C programming skills and any C programmer comfortable with the language can not only immediately read most FORTRAN, but can modify it as well.
