Programming Paradigms
A Programming Paradigm is a fundamental style of computer
programming.
In Functional Programming a program can be thought of as a
sequence of stateless function evaluations.
In Object Oriented Programming, programmers can think of a
program as a collection of interacting objects.
Process Oriented Programming allows programmers to think
about applications as sets of concurrent processes acting upon
logically shared data structures.
Object Oriented Programming
Object Oriented Programming ( OOP ) is a programming
paradigm that uses "objects" – data structures consisting of data
fields and methods together with their interactions – to design
applications and computer programs.
Programming techniques may include features such as data
abstraction, encapsulation, modularity, polymorphism, and
inheritance.
