Fortran (; formerly FORTRAN, derived from Formula Translation) is a general-purpose, compiled imperative programming language that is especially suited to numeric computation and scientific computing.
Originally developed by IBM in the 1950s for scientific and engineering applications, FORTRAN came to subsequently dominate scientific computing. It has been in use for over six decades in computationally intensive areas such as numerical weather prediction, finite element analysis, computational fluid dynamics, geophysics, computational physics, crystallography and computational chemistry. It is a popular language for high-performance computing and is used for programs that benchmark and rank the world's fastest supercomputers.Fortran has had multiple versions, each adding extensions while largely retaining compatibility with prior versions. Successive versions have added support for structured programming
and processing of character-based data (FORTRAN 77), array programming, modular programming and generic programming (Fortran 90), high performance Fortran (Fortran 95), object-oriented programming (Fortran 2003), concurrent programming (Fortran 2008), and native parallel computing capabilities (Coarray Fortran 2008/2018).
Fortran's design was the basis for many other programming languages. Among the better-known is BASIC, which is based on FORTRAN II with a number of syntax cleanups, notably better logical structures, and other changes to work more easily in an interactive environment.As of June 2021, Fortran was ranked 17th in the TIOBE index, a measure of the popularity of programming languages, climbing 17 positions from its ranking of 34th in January 2020.
Let's say you have an array A and a variable B (both reals). Apparently
parameter (A = (/1.2, 3.4, .../) )
is illegal, so you have to do
data A /1.2, 3.4, .../
instead. However, what if you have a statement afterwards like this?
1 parameter (A = (/1.2, 3.4, .../) )

not sure where this goes, but I am trying to look for a fortran compiler for my windows XP OS that is free so i can get into doing some programming. My school may be getting into a engineering competition and i would be a frontrunner on the team and want to get a headstart. if anyone can help i...

hello everyone!
I was do programming in fortran and i wanted to print my answer in the format below. I was not able to do it. I have written a part of my program also.
i.e,

Hi , I need help to write a code for this function(fortran 77):
integer function delete(id, list, n) where
• delete returns 0 if the deletion was successful, -1 if the list is empty, and -2 if the user is not currently in the list.
•id is the integer identification number of the user...

i'm new with programming and i have a problem with a homework I've been assigned from university. it's quite a simple programm but I'm stuck and going crazy . can anyone please help. there seems to be a problem with the random function. but i couldn't fix it. I'm using...
It appears that the newer versions of Fortran might be the best environment for technical computing. Aside from Matlab at least. It also appears that very few entities use Fortran. Is Fortran 90/95/2003 worth learning if all I really want to do is put it on my resume?
Im writing a program in fortran 90. what I am trying to get it to do is to open an input file for another program, change a few variables. then run that program. Then when the program is done running it will change the variables in the input file again and run the program. This will be a Do...

As a chemical engineer how useful would FORTRAN be to me. It is listed on the University of Florida's ChemE homepage as a good language, but I have heard it is on its way out.
All Comments Welcome
I've written a program in Fortran which has a do loop of the form
do i=0,20000
(operations)
end do
I want the program to print the values of the do loop, but only want it to print every 100th value of i (i.e. 100,200,300,400...20000), can anyone suggest a way to do this?

I'm in the first year of mechanical engineering and can't afford a Fortran textbook.
Does anyone have a beginners guide that would be suitable for the level I need to learn? I need to know that basics.
Thanks in advance my friends.
