Q. C# Program to Print Fibonacci Series upto N terms.

Here you will find an algorithm and program in C# programming language to print fibonacci series. First let us understand what fibonacci series means.

Explanation : The Fibonacci sequence is a sequence consisting of a series of numbers and each number is the sum of the previous two numbers. For Example :- 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, …….

START
  Step 1->Declare variables i, a, b, nextTerm
  Step 2->Initialize the variables, a=0, b=1, and nextTerm = 0
  Step 3->Enter the number of terms of Fibonacci series to be printed
  Step 4->Repeat below steps n times
   -> print the value of a
   -> nextTerm = a + b
   -> a = b
   -> b = nextTerm
   -> increase value of i each time by 1
STOP

C# Program to Print Fibonacci Series

using System;  
public class Demo{  
   public static void Main(string[] args){  
      int a = 0, b = 1, nextTerm, i, n = 9;
      for(i=0 ;i < n; ++i){    
         Console.Write(a+" ");
         nextTerm = a + b;   
         a = b;    
         b = nextTerm;
      }    
   }  
}

Output

0 1 1 2 3 5 8 13 21
