>[How to call] Objective C from C
I recommend reading a book on programming Objective C. It is very natural in the language to call Objective C from C.
Objective-Whatever is an OO paradigm "bolt-on" or hybrid that can be used to OO enhance almost any language (but in particular procedural languages). Thus Objective-Pascal, Objective-C, Objective-C++.
