About this program

This is an example program in c common example program. Read the concept first: C++ Variables and Data Types, then study the code and output below.

Definition

In mathematics, the Fibonacci numbers or Fibonacci series or Fibonacci sequence are the numbers in the following integer sequence:

1 1 2 3 5 8 13 21 34 55 89 144 ......

By definition, the first two numbers in the Fibonacci sequence are 0 and 1, and each subsequent number is the sum of the previous two.
