Objective-C is a reflective, object-oriented programming language that adds Smalltalk-style messaging to C.

It is a very "thin" layer on top of C, which makes Objective-C a strict superset of C. That means it is possible to compile any C program with an Objective-C compiler -- something that cannot be said of C++ ...

Objective-C derives its syntax from both C and Smalltalk. Most of the syntax (including preprocessing, expressions, function declarations and function calls) is inherited from C, while the syntax for object-oriented features was created to enable Smalltalk-style message passing.
