Fibonacci Series in C#: In case of fibonacci series, next number is the sum of previous two numbers for example 0, 1, 1, 2, 3, 5, 8, 13, 21 etc. The first two numbers of fibonacci series are 0 and 1. Let's see the fibonacci series program in C#.

💻 Program Code

using System;
public class FibonacciExample
{
    public static void Main(string[] args)
    {
        int n1 = 0, n2 = 1, n3, i, number;
        Console.Write("Enter the number of elements: ");
        number = int.Parse(Console.ReadLine());
        Console.Write(n1 + " " + n2 + " "); //printing 0 and 1    
        for (i = 2; i < number; ++i) //loop starts from 2 because 0 and 1 are already printed    
        {
            n3 = n1 + n2;
            Console.Write(n3 + " ");
            n1 = n2;
            n2 = n3;
        }
    }
}

🖥 Program Output

Enter the number of elements: 10
0 1 1 2 3 5 8 13 21 34 Press any key to continue . . .

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
