What is Objective-C?

Objective-C was invented in the early 1980s by Dr. Brad Cox. The language was developed as an Object-Oriented layer on top of the popular C programming language (in this FAQ and in much other documentation on Objective-C, knowledge of C or a related language is assumed). Cox’s original implementation was a preprocessor which generated C code, and was marketed by Stepstone. Objective-C is a true superset of C, so the language may vary depending on what version of the C language is supported by the compiler. The additions to C are few: a handful of new keywords, three extra types (of which only one, id, is frequently used) and the message-sending syntax.
