I use the outer ones as the standard process this file once.

The inner ones (when used are to grab things that I know have to be
 grabbed to make this file work.

I had the same problems with recommending books. I have about at least
 six C and C++ books and I still go online to find information. K&R is
 as good as any (for C) I use teach yourself C++ from SAMS mostly, but
 I don't think it's that good. I haven't found anything good for embedded C.
