Here we assume the series starts with two ones, that is 1, 1, 2, 3, 5, 8,13, 21, 34, 55, 89, 144, Program should at least consists of the main() function and two recursive function with return value. 1) Define a recursive function fib0 with return that calculates the nth Fibonacci number in the 2) Define another recursive function fibSumO with return value that calculate the sum of first a) Read a positive integer n with proper prompt. Here n is the length of the Fibonacci series. n Fibonacci numbers in the series. 3) In main0 series. b) Call fibO to calculate and display first n Fibonacci numbers. We assume that the first 1 Fibonacci number is 1 and the first 2 Fibonacci numbers are 1, 1. c) CallfibSum to display the sum of first n Fibonacci numbers. Note: n-L ^^d fih C..mll milst he recursive functions with return value
