C - Possible to create a tree level by level?

I'm studying trees right now, and I'd like to find some examples of how to create a binary(or k-ary) tree one level at a time, since I can't find it anywhere and my brain isn't working.

Anyone have any input on this? C's lack of functions doesn't help either. Thanks ahead, /prog/

welcome to /prog/
lots of people here will tell you to read this 600-page reference book or that massive library of code without offering any help. also, prepare to be ridiculed and ostricized because you're not in the clique. yep, it's exactly like high school - lonely teenagers being jerks to each other. don't mean to get you down, but if you really need programming help, this isn't the place to get it.

i love how all the clique-kids sage any post that they recognize is not theirs
