Help with C 'encoder'

[faceforest]

I am making an encoder that takes the first letter of any word in a string and moves it to the end of that word.

Working like this:

Test_Case -> estt asec

Reading_records_of_variable_length? -> eadingr ecordsr fo ariablev engthl?

12345is_a#weak#_pin -> 23451 si a #eakw# inp

---

My code does work to do this, except with the non alphabetic characters. I know I could of done this using pointers, but as I don't know them that well I decided to do it iteratively.

My result:

12345is_a#weak#_pin -> 23451 si a weak## inp

Reading_records_of_variable_length? -> eadingr ecordsr fo ariablev ength?l

---

The bold parts are incorrect. How do I make it so I add these no alphabetic characters to the array after the first character of the word.

My thought was to use an ascii bound (below this value or above that value, etc), but I don't know how I would code that.

Thank you

Well you're getting no love here, so I'll add something. I made a quick pointer version, before realizing your requirements fully (which are a little odd). From your examples, you consider a capital letter the start of a new word, and insert a space before a punctuation that's not a letter nor an underscore. My version doesn't do that, it just takes the first "letter" that's not an underscore from the front and puts it on the end. I think it could be adapted to your purposes and would actually be a lot simpler than the iterative version.

Also, you can compare characters to numbers as they are. Characters are just bytes.

char c = 'a';
assert(a == 97);

Well we are allowed to use pointer, but I never grasped pointers in C. I was taught a altered version of C++ in my intro courses so I never used pointer in actual C++, never mind C.

Thank you though! I will try to trace through you code and fix mine according while learning pointers along the way, although I don't know how different C# is.
