Program to identify prime numbers

• A prime number is a positive integer greater than 1 that has no positive integer divisors other than 1 and itself

• One way to check if a number is prime is to divide it by all numbers less than or equal to its square root

• Another way is to use the Sieve of Eratosthenes algorithm to generate all prime numbers up to a given limit

• Prime numbers are important in cryptography and number theory

Oops concept is a programming paradigm that focuses on objects and their interactions.

• Oops stands for Object-Oriented Programming System

• It is based on the concepts of classes and objects
