female hurricanes are more deadly than male
hurricanes?

The Fibonacci series 0, 1, 1, 2, 3, 5, 8, 13, 21 … begins with
the terms 0 and 1 and has the property that each succeeding term is
the sum of the two preceding terms. Write a non-recursive function
Fibonacci (n) that calculates the nth Fibonacci number. Write a
program to display a table of terms and the Fibonacci number in two
columns for the first 15 terms, using the function you
created.
