OOP is programming which is oriented around objects, thus
taking advantages of encapsulation, polymorphism and
inheritance to increase code reuse and decrease code
mantenance.

In procedural program, programming logic follows certain
procedures and intructions are executed one after another.
In OOP unit of program is object which is nothing but
combination of data and code.
