To check whether the number is prime or not.
using System;
  public class PrimeNumber
   {
     public static void Main(string[] args)
      {
          int n, i, m=0, flag=0;
          Console.Write("Enter the Number : ");
          n = int.Parse(Console.ReadLine());
          m=n/2;
          for(i = 2; i <= m; i++)
          {
           if(n % i == 0)
            {
             Console.Write("Number is not Prime.");
             flag=1;
             break;
            }
          }
          if (flag==0)
           Console.Write("Number is Prime.");
     }
   }
To print Fibonacci Series.
using System;
  public class Fibonacci
   {
     public static void Main(string[] args)
      {
         int n1=0,n2=1,n3,i,number;
         Console.Write("Enter the number of elements: ");
         number = int.Parse(Console.ReadLine());
         Console.Write(n1+" "+n2+" ");
         for(i=2;i
         {
          n3=n1+n2;
          Console.Write(n3+" ");
          n1=n2;
          n2=n3;
         }
      }
   }
To check whether the number is Odd or Even.
using System;
public class EvenOdd
{
    public static void Main(string[] args)
    {
        int num;
        Console.WriteLine ("Enter the number");
        num=int.Parse(Console.ReadLine());
        if(num % 2==0)
        {
            Console.WriteLine("number is even");
        }
        else
        {
            Console.WriteLine("number is Odd");
        }
    }
}
