Let’s find out a simple and easy way to code the program.

Practical Implementation:

using System;

namespace patternProblem.Simple_program
    class Simple6   //checking number prime or not
        static void Main(string[] args)
            Console.Write("Enter a number: ");
            int n = Convert.ToInt32(Console.ReadLine());
            int i = 0;
            if (n < 2)
                Console.WriteLine("Smallest prime number is 2");
            for (i = 2; i < n; i++)
                if (n % i == 0)
                    Console.WriteLine("Not Prime number");
            if (n == i)
                Console.WriteLine("Prime number");


The input number here is 3. The program will check with the number is prime or not. The output is shown below:
