Fibonacci series in c# using recursion

In this blog, weâ€™ll explore the c# program to the Fibonacci series using recursive. Weâ€™ll also cover advantages and considerations as we delve further into the blog.

Overview of the Fibonacci Series:

The Fibonacci series is a sequence where each number is the sum of the two preceding ones, typically starting with 0 and 1. Its allure lies in its occurrence in nature and diverse mathematical applications.

C# as the Canvas:

C# stands as a powerful canvas for mathematical computations and algorithmic expressions. Its syntax and structure provide a conducive environment for crafting solutions that mirror the elegance of mathematical concepts.

How to display fibonacci series in C# using RecursionÂ

Recursion, a programming technique where a function calls itself, is a natural fit for expressing the Fibonacci series. In C#, the recursive approach captures the essence of the mathematical definition, creating code that is both intuitive and elegant.

```using System;
public class fibonacciExample {
public static void Main(string[] args) {
fibonacciExample ex = new fibonacciExample();
int val = 10;
int res = ex.displayFibonacci(val);
Console.WriteLine("{0}th number in fibonacci series = {1}", val, res);
}
public int displayFibonacci(int n) {
if (n == 0) {
return 0;
}
if (n == 1) {
return 1;
} else {
return displayFibonacci(n - 1) + displayFibonacci(n - 2);
}
}
}```

Explanation of the code:

1. Class Definition:

â€“ The class fibonacciExample encapsulates the code for calculating Fibonacci series.

2. Main Method:

â€“ The Main method is the entry point of the program.

â€“ An instance of fibonacciExample is created.

3. `displayFibonacci` Method:

â€“ Recursive method that calculates the nth Fibonacci number.

â€“ If n is 0, it returns 0. If n is 1, it returns 1.

â€“ For n greater than 1, it calls itself recursively for n-1 and n-2 and returns the sum.

4. Output Display:

â€“ The Main method displays the result for the 10th number in the Fibonacci series.

Output:

``10th number in fibonacci series = 55``

The code elegantly demonstrates the recursive nature of Fibonacci series calculation in C#. Each number is the sum of the two preceding ones, providing a clear and concise representation of this mathematical sequence.
