/*

The following program is to generate n terms in the fibonacci series.

fibonacci series is defined as......

a(n) = a(n-1) + a(n-2)

and a(0) = 0, a(1) = 1

the first 5 terms in the fibonacci series are....
0, 1, 1, 2, 3

the first 10 terms in the fibonacci series are...
0, 1, 1, 2, 3, 5, 8, 13, 21, 34
