Fibonacci Series in C Sharp

Fibonacci Series

A Fibonacci series is a series of numbers where the next number is a sum of the previous two numbers.

For example, a Fibonacci series with the first two numbers of 1 and 2 is:

1, 2, 3, 5, 8, 13, 21, 34 etc.

Example:

using System;  
  public class Example  
   {  
     public static void Main(string[] args)  
      {  
         int x=1, y=2, z, i, n;    
         Console.Write("Enter the number of elements: ");    
         n = int.Parse(Console.ReadLine());  
         Console.Write(x + " " + y + " ");   
         for(i=2; i<n; ++i)     
         {    
          z = x + y;    
          Console.Write(z + " ");    
          x = y;    
          y = z;    
         }    
      }  
   }

Output:

Explanation:

In the above example, we are printing a Fibonacci series starting with 1 and 2 in C#.
