Help in C Programming: Fixing Errors with nr.h & nrutil.h Libraries

AI Thread Summary
The discussion centers on the C libraries nr.h and nrutil.h, which are essential for using numerical integration functions like qromb, polint, and trapzd. Users are encountering compilation errors indicating that these header files cannot be found. The conversation emphasizes the need to properly include these libraries in the project to resolve the "No such file or directory" errors. Suggestions for fixing the issue include ensuring that the libraries are correctly downloaded and placed in the appropriate directory, as well as checking the include paths in the compiler settings. The linked resource provides additional context and guidance on using these libraries effectively.

What are the functions of the following C libraries?
nr.h
nrutil.h
What I understood is that these are used when u are calling functions like 'qromb or polint or trapzd' for integration. Acutally when I compile the program I get these errors.
nr.h: No such file or directory
nrutil.h: No such file or directory
I searched in net , but can't fix it. How can I add those libraries?

I was not able to figure this out during the interview, but I have been look in this all weekend and I read something online that said it can be done at O(N) using something called the counting sort histogram algorithm ( I did not learn that in my advanced data structures and algorithms class). I have watched some youtube...
