The Code Complete 1-2 books is exactly what i've been looking for. But some of the concepts are unfamiliar for me. I will read C-FAQs first to gain some more experince. My first C book was The C Programming Language (ANSI C - 2nd Edt.) by K&R. This should be good reference book but currently i dont have that. *Harbison, Samuel P. and Steele, Guy L., C: A Reference Manual, Fourth Edition. Prentice-Hall, *The subject is too broad and i want to stay in embedded side of C world. Actually, in Windows i use Labwindows/CVI. ANSI-C IDE that fits all of my GUI design needs. I dont need "++" headeche for now. As an invidual developer C fulfill all of my design considerations. All of my searches are for a bit discipline and professionalism.. IMO most of the important guidelines are generic and not specific to C.
