# C# Program To Print A Fibonacci Series

###### Tutorialsrack 04/08/2019 C# Programs

In this C# program, we will learn how to write a program to print a Fibonacci series.

## What is the Fibonacci Series?

In mathematics, the Fibonacci numbers, commonly denoted Fn form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from 0 and 1. That is,

F0=0 and F1=1

And

Fn=Fn-1 + Fn-2

Example of Fibonacci Series is  0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 and so on.

Here is the code of the program to print a Fibonacci series:

##### Code - C# Program To Print A Fibonacci Series
``````using System;

namespace TutorialsrackPrograms
{
class Program
{
//Program to print a Fibonacci Series
static void Main(string[] args)
{
int a = 0, b = 1, c = 0;
Console.Write("Enter The Number: ");
Console.WriteLine();
Console.Write("Fibonacci Series:\t");
Console.Write("{0} {1}", a, b);
for (int i = 2; i < len; i++)
{
c = a + b;
Console.Write(" {0}", c);
a = b;
b = c;
}
}
}
}``````
##### Output

Enter The Number: 10

Fibonacci Series: 0  1  1  2  3  5  8  13  21  34
