Formula into C code...

[Daikide]

I need to translate this formula into C code, but I know very little programming. Can anyone help?

Read a C tutorial and pay special attention to the math functions available.

The moderators on this forum are particularly uncompromising when it comes to answering such questions directly even though it will probably take you a long time to write that code from zero knowledge but would take anyone with a little experience 30secs. It's a great idea to learn C or C++ but if it's auxiliary to your profession, then this might not be what you came here to be told.

Anyway, I suggest you start by writing a "hello world" program. You can copy-paste the code for that from anywhere. Once you get that going, perhaps I'm allowed to tell you that the main ingredients you'll need will be an array to store your x_i values which can be an array in the C sense "int a = {1, 1, 2, 3, 5, 8};" or, even better, a vector. Then a you'll need a for() loop and the abs() absolute value function.

Schools, colleges and universities are tough cookies when they discover copied
and pasted spoonfed solutions; they not only consider it cheating on behalf of the
student but they also go after the source of the spoonfed solution. And ever so
right they are. TSDN doesn't want to be a source of spoonfeeding nor cheating.

Even more important: suppose you're a professional software developer and also
suppose someone got away with the cheating, graduated and becomes your
co-worker. You'd have a double task/job then: doing your own thing as well as
cleaning up the mess created by your cheating co-worker.

kind regards,

I'm not a professional programmer but my experience gives me a different view about how to learn programming. Anyway, I won't mention it again. I think TSDN is a great site and I will abide by its rules.

To at least make my message relevant to this thread, Daikide you should will always get a better response to your question if you demonstrate some attempt to solve it yourself. Post some code you're having difficulty with. If you don't know C or C++ at all and want to learn it, then you can ask for advice about that specifically.

The OPs question has (almost) nothing to do with C or C++; we can only guess
if the question has something to do with theoretical function theory, possibly with
a finite domain D and a finite co-domain C, i.e.f(D) --> C. What are we supposed
to answer? If f() is a surjection, injection of bijection? The cardinality of [D], |C|
can tell a lot before digging into gory details.

Just marking the particular c_i for a d_i can tell the rest.

kind regards,
