PR013 - Programming in Objective C

Summary

(2 days)

Objective-C is a powerful, easy-to-learn, object-oriented extension to C. Unlike in C++, advanced object-oriented features like dynamic binding, run-time type identification, and persistence are standard features in Objective-C which apply universally and work well together. Moreover, the support for descriptive message names (a la SmallTalk) makes Objective-C code easy to read and understand. Objective-C is supported by the GNU and NeXTSTEP C compilers.

Objective-C is the primary language used for Apple's Cocoa API, and it was originally the main language on NeXT's NeXTSTEP OS. Generic Objective-C programs that do not utilize these libraries can also be compiled for any system supported by gcc ,
You can use Objective C to develop full fledge applications. Apple has selected Objective C as primary programming language for Mac machine and iPhone. So, you can use Objective C to develop applications for these devices.
