I think I have two methods to using the fortran 90 program. First, compile all the .f90 and .cpp to .obj, and link them. Second, make the fortran... 31 Mar 2008 17:57

passing fortran arrays
Hi everybody, I try to pass a Fortran array to a c++-function, assuming that the name of the fortran array is a pointer, indicating the first element. it looks like this: the fortran file: program arrayfc implicit none integer,parameter :: n=5 integer :: stopp,SUMME real :: a(n),sum,mw,MITTELWER... 2 Feb 2008 11:19

how do gfortran and ifort deal with C head files?

I think ifort and most other Fortrans behave similarly. As noted above, if the source file has a .F or .F90 file type, the .F or .F... 2 Feb 2008 09:07

Fortran user models Intra-Day Stock Market
To: "dpb" I cant reply to your sarcastic comment of 1/2/2008 as similiar named topic is too old to be seen by readers here. Further your none.net address rules out email responses to your posts from readers. You will be overjoyed (dismayed?) to learn that the last 10 days of forecasts have resulted in a Win... 2 Feb 2008 04:34

Sort of, but you are missing an important point. This is Fortran's model. As such, it is much like the some common machine repres... 1 Feb 2008 11:59

What's the meaning of "a model set of integers (reals)" in Fortran?
Hi, everyone. I'm reading a book titled "Fortran 90/95 Explained" to learn Fortran by myself. My major is chemistry, so this question might be silly. In section 8.7.1 models for integer and real data. The authors wrote: For each kind of integer, it is the set i = s \times \sum_{k=1}^{q} w_k \times r^{k-1} ... 1 Feb 2008 05:45

Which direction is Fortran going?
Use to see Fortran compilers and books in the computer stores, but now they don't even know what I'm talking about. A friend is a recent graduate with a degree in engineering from an accredited university and knows many program languages but no Fortran. Why is that? If you need to solve a complex engineering p... 1 Feb 2008 15:53
