Task of Challenge #14/54

Print the first 10 Fibonacci numbers without recursion.

Fibonacci series: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, …



We start with the creation of the for loop. We have to define the loop is running from 2 to 10 in order to get the first 10 numbers. We start with the 0 and the 1 and need 8 more.

Any number n of the Fibonacci series is created by adding up the number n-1 with the number n-2.

To get the third number, we need to have number n-1 and n-2. With n = 3, this will be number 2 and 1 of the series.

The equation is therefore:

n = n – 1 + n – 2;

Result into:

2 = 1 + 0; The 3rd number of the Fibonacci series.

Then we need to switch the n – 1 and n – 2 to the newly created ones to go further in our Fibonacci series. E voilá, do it as long as you want to get all numbers for the Fibonacci series.

The complete outcome of the console:
