Function Fibonacci


Objetive:

Create a program that uses recursion to calculate a number in the Fibonacci series (in which the first two items are 1, and for the other elements, each one is the sum of the preceding two).


Source Code:

 
using System;
public class F_Fibonacci
{
    public static int Fibonacci(int number)
    {
        if ((number == 1) || (number == 2))
            return 1;
        else
            return Fibonacci(number - 1) + Fibonacci(number - 2);
    }

    public static void Main()
    {
        int number;

        Console.Write("Enter a number: ");
        number = Convert.ToInt32(Console.ReadLine());

        Console.WriteLine("Fibonacci of {0} is {1}", number,
         Fibonacci(n));
    }
}
