How to get fibonacci in c#
<p>Guys I have a question regarding on fibonacci..How do I get the fibonacci series that the number will also end on user input...example if I put 21 the output must be 0 1 1 2 3 5 8 13 21</p>

<p>This is my code</p>

<pre><code>    static void Main(string[] args)
    {

        int input, first = 0, second = 1, third = 0;
        Console.Write("Enter a number : ");
        n = Convert.ToInt32(Console.ReadLine());
        Console.Write("First {0} Fibonacci numbers {1} {2} ", input, first, second);

        for (int i = 3; i &lt;= input; i++)
        {
            third = first + second;
            Console.Write("{0} ", third);
            first = second;
            second = third;
        }
