Object-oriented programming (OOP) is a programming paradigm
that represents concepts as "objects" that have data fields
(attributes that describe the object) and associated
procedures known as methods. Objects, which are usually
instances of classes, are used to interact with one another
to design applications and computer programs
In Procedural Programming language the execution of
application can be step by step.
that means there is no need to follow the order of
execution on OOP.
it depends on the object.

Write a C++ program without using any loop (if, for, while etc) to print prime numbers from 1 to 100 and 100 to 1 (Do not use 200 print statements!!!)
