What is Objective C ?

• Objective-C is the primary programming language used when writing software for OS X and iOS.
• It’s a superset of the C programming language and provides object-oriented capabilities and a dynamic runtime.
• Objective-C inherits the syntax, primitive types, and flow control statements of C and adds syntax for defining classes and methods.
• It also adds language-level support for object graph management and object literals while providing dynamic typing and binding, deferring many responsibilities until runtime.
