any good C/fortran code sites?

here's the story. I'm a grad student in theoritical chemistry. I'm very comfortable in java, but don't know any other language. Unfortunately, the field uses fortran and C for it's programs. Anyway, my final project for my statistical mechanics course involves disecting some code in both fortran and C, but i don't know any of the syntax.

do any of you have/know of any sites that are very user friendly and informative for looking up C/fortran syntax?

thanks all!

If your comfortable with Java, then C/FORTRAN should be a snap.

C and FORTRAN have maybe 20 STATEMENTs, all which java does, just a matter of syntax, though probably what you are asking.

Either google or buy some cheap books.

www.bookpool.com

seems, not many cheap books there...

You'll have little problem learning C, as it closely parallels J for most conventions.

You may have a harder time with Fortran, especially considering if its an older version. F9x should prove safe enough for a person experienced with J, but if your using something like Fortran 7x, then I definitely recommend obtaining a good programming guide. My scientific application development classes required F77, and it was not too fun having to deal with the archaic code conventions.

cool, thanks for the advice rob... i'm not sure w/ version it is... .i hope that it's fortran 90, but not positive... we'll see

Is that the first six columns of a line are 'reserved' (one is comment, a few are for branching/goto, forgot the others.. Or are you really old school and no for/while loops?

Regardless being 2003, hopefully it's the FORTRAN I was doing 7 yrs ago, and that was pretty easy, though no OO!

Fotran 77 is the wonderful world of never ending "goto" statements. Test loops are available, but most other control options were non-existent.

And yes, the first series of columns are reserved. Worst part? We developed applications on a shell account on a VAX system. Definitely not the high point of my education.

Aahh the GOTO.

Did that in college, talk about spaghetti code. Loops really do make a difference...
