## 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, …….

## Fibonacci Series Algorithm

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
