Objective C is an Object-Oriented programming language and gets its object oriented feature from smalltalk.
Its dynamism frees a program from compile-time and link-time constraints.
shifts much of the responsibility for symbol resolution to runtime when the user is in control.
Objective C is more dynamic than other programming languages because its dynamism springs from three sources:
1. Dynamic typing - means determining the class of an object at runtime
2. Dynamic binding - means determining the method to invoke at runtime
3. Dynamic loading - means adding new modules to a program at runtime
