Fibonacci series :-The Fibonacci sequence is a series of numbers starting with 0 and 1 where a number is the addition of the last two numbers, for example 0, 1, 1, 2, 3, 5, 8, 13 etc.
Algorithm:-
(1)Start
(2)take four variable n1,n2,n3,num with n1 and n2 initial value zero and one
(3)take number from user for print fibonacci series and store in num
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleProgrammPractice
{
class Program
{
static void Main(string[] args)
{
try
{
int n1 = 0, n2 = 1, n3, num;
Console.Write("Enter the number of elements to print Fibonacci series: ");
num = int.Parse(Console.ReadLine());
Console.Write(n1 + " " + n2 + " ");
for (int i = 2; i < number; i++)
{
n3 = n1 + n2;
Console.Write(n3 + " ");
n1 = n2;
n2 = n3;
}
}
catch (Exception ex)
{
Console.WriteLine("input is not in correct formate");
}
Console.ReadKey();
}
}
}
Output:-
Enter the number of elements to print Fibonacci series: 10
0 1 1 2 3 5 8 13 21 34
