The definition of Objective-C

(related variations: Objective-C ObjC)
Objective-C (often called "ObjC" for short) is a compiled object-oriented language. Based heavily on C, Objective-C is nearly as fast and can often be thought of as being just C with added features. Note that it was developed independently of C++; its object-oriented extensions are more in the style of Smalltalk. It is however related to Objective-C++.
