## Fibonacci Series

This program will help you to print Fibonacci series on your console screen.. If you don't know about Fibonacci series it is something like this:

**0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55,......................**

A new number in the series comes after the sum of last two numbers in the series like 0 + 1 = 1, so the third number is 1 and then 1 + 2 = 3, so the next number is three and so on...

Here is the output of the program I made:
