Objective-C is an object-oriented programming language. It was named after the concept of adding objects to the C language.
Objective C was introduced with NeXTSTEP and OPENSTEP, and was considerably extended in application due to its use with the Cocoa libraries under Mac OS X or the GNUstep libraries. However, you can program in Objective-C without these libraries if you wish.
Because not everyone uses OPENSTEP or Mac OS X, we will introduce these library-specific details later.
Familiarity with the C programming language is required, as Objective-C shares a lot with it, hence its name.
