In this article we will show you how show a fibonacci series
In mathematics, the Fibonacci numbers, commonly denoted Fn, form a sequence, the Fibonacci sequence, in which each number is the sum of the two preceding ones.
The first two numbers of fibonacci series are 0 and 1., although some authors omit the initial terms and start the sequence from 1 and 1 or from 1 and 2. Starting from 0 and 1, the next few values in the sequence are:[1]
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, …
Example
using System;
namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
int n1 = 0, n2 = 1, n3, i, myNumber;
Console.Write("Enter the number of elements: ");
myNumber = int.Parse(Console.ReadLine());
Console.Write(n1 + " " + n2 + " "); //print 0 and 1
for (i = 2; i < myNumber; ++i) //loop starts from 2
{
n3 = n1 + n2;
Console.Write(n3 + " ");
n1 = n2;
n2 = n3;
}
Console.ReadLine();
}
}
}
Here is a test run
Enter the number of elements: 15 0 1 1 2 3 5 8 13 21 34 55 89 144 233 377
