maybe mathematica.stackexchange.com/questions/8841/… or calculuslab.deltacollege.edu/ODE/7-1/7-1-0-c-mma.html also this is useful stackoverflow.com/questions/8905726/…

.. just saw eldo post after hitting post.... This is a little different may be. In Mathematica, we should always try to come up with 10 different ways to solve something :)

comment Formatting Fortran complex number output for use in Mathematica
How did you use "Import"? Please provide example of the data in the file, and the command you used. M can import Fortran data reference.wolfram.com/mathematica/tutorial/…

comment Formatting Fortran complex number output for use in Mathematica
How did you "get" the array from Fortran to look like this in first place and have it land inside Mathematica? Was the data in file and you imported it into Mathematica?

comment What's a non-trivial Mathematica program involving conscious choice of stack vs. queue data structure?
I also do not think Mathematica is the right choice for computer science algorithms course, since it is a high level language. Same as Matlab is not a good choice, and neither is Maple. We used Pascal for this at school where one can 'see' things. In higher level languages, the need to implement such data structures is not needed as much as in low level and system programming.

M is a high level language (4th generation if you will), so most of the time, you do not need to implement these data structures since they are not needed, Mathematica commands already there to do pretty much anything you want. But if you want to implement them you can. Here is a link that shows how to library.wolfram.com/conferences/devconf99/lichtblau

comment To solve an equation
is c>0? if so, int = Assuming[c > 0, Integrate[(2 c - (r^2) Exp[-I 1.4746])^(0.5), {r, 0, 31.7576}]] gives the answer in Hypergeometric2F1

This could be a bug, as help says it is supposed to combine them.

comment How to use Assumptions in a Series Expansion
@MichaelE2 fyi, Wolfram alpha was smart enough to parse part of this command even in Latex! It gave back Series Sqrt, ok not exactly the full command, but very impressive none-the-less !Mathematica graphics may be in the future with more AI it will be able to process full latex input as well.

comment How avoid white space and tags in CDF on web page
the unwanted space can be easily taken care off with correct width and height values in your HTML command to load the CDF. Screen shot !Mathematica graphics I just used <embed src="Untitled.cdf" width="400" height="400"/> and the yellow color is because your set the page color to yellow. I just removed that. In V9, there is an export CDF in the menu, selecting export standalone CDF, you should get the same result as I have.
