I've noticed that when my fortran code is running, the executable generates several temporary files with the name patter fort* where * is a 6 digit alpha numeric. The number of files generated corresponds to the number of threads the program is running on. The files are cleared once the program exits.
What are these files? And what is stored in them?
Edits: The program has no commands that generate these files.

I have a question in CUDA programming.
Is there a way to obtain a module by accepting the contents of a *.cu file as a string rather than loading a *.cu file and compiling with cubin? I'd like to utilize nvrtc if possible.
I wrote most of the code using nvrtc, and I'm looking for a way to not create external files like cubin.

I have read many places that bits/stdc++.h contains all the header files that are useful in competitive programming, for saving time.
Can anyone give me any source for it or give the list in the of its header files?
You can open the file in the path where your all the c++ header files are kept. (Locate the file stdc++.h).
Or you can get one of the versions of the file in the link described here:
stdc++.h

I am a fairly new C++ programmer and I am trying to set up a program that moves 2 files into a different location. How do I do this?
Under Windows, there is an API just for that purpose, the MoveFileEx() function.
To use it, start with:
#include <windows.h>
And then you can simply do something like this:
BOOL result = MoveFileEx("C:\\dir\\myfile.txt", "D:\\another\\directory\\output.txt", MOVEFILE_COPY_ALLOWED);

I need to compare 5 files by their file paths: a,b,c,d,e and find duplicates if exists.
How can I do this in c++ via md5sum comparison of files?
You'd need to compute a checksum for each file (write it yourself or call an external program), get hold of each file, ... This depends on the operating system. It is much easier to do something like this in a scripting language.

I have seen lot of tutorials and documentation on how to get the files descriptors from a given pid. Well, I want to do otherwise.
Thanks.
Of course not, that's like trying to get the PID that called main. Every process has a file descriptor 0 (stdin), 1, 2, etc., and they mean different things for each process.
A file descriptor, which is just a small integer, isn't meaningful unless you already know what process you are talking about.
