Enter the number of elements: 0 1 1 2 3 5 8 13 21 34
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+" "); //printing 0 and 1
for(i=2;i<number;++i) //loop starts from 2 because 0 and 1 are already printed
{
n3=n1+n2;
Console.Write(n3+" ");
n1=n2;
n2=n3;
